## Overview
|
||||
|
||||
ROA2WEB uses a **hybrid CSS architecture** combining:
|
||||
- **Global patterns** (`src/assets/css/`) for reusable components
|
||||
- **Scoped styles** (`<style scoped>`) for component-specific logic
|
||||
- **Design tokens** (`var(--color-primary)`) for consistency
|
||||
- **Zero `:deep()` overrides** for PrimeVue (centralized in `vendor/primevue-overrides.css`)
|
||||
|
||||
### Goals
|
||||
|
||||
✅ **Eliminate duplication** - Write CSS once, use everywhere
|
||||
✅ **Maintain consistency** - Same patterns across the app
|
||||
✅ **Improve maintainability** - Easy to update and scale
|
||||
✅ **Reduce bundle size** - Less CSS = faster load times
|
||||

||||

|
||||
|
||||
## Decision Tree
|
||||
|
||||
### "Should I write CSS for this?"
|
||||
|
||||
```
|
||||
Need to style a component?
|
||||
│
|
||||
├─ Does this pattern exist in another component?
|
||||
│ ├─ YES → Use global CSS (check docs/CSS_PATTERNS.md)
|
||||
│ └─ NO → Continue to next question
|
||||
│
|
||||
├─ Is this a form/button/card/table?
|
||||
│ ├─ YES → Use global CSS (forms.css, buttons.css, cards.css, tables.css)
|
||||
│ └─ NO → Continue to next question
|
||||
│
|
||||
├─ Is this a PrimeVue component?
|
||||
│ ├─ YES → Check vendor/primevue-overrides.css (NEVER use :deep() in components!)
|
||||
│ └─ NO → Continue to next question
|
||||
│
|
||||
├─ Is this a dashboard pattern (page header, metrics, breakdown)?
|
||||
│ ├─ YES → Use global CSS (patterns/dashboard.css)
|
||||
│ └─ NO → Continue to next question
|
||||
│
|
||||
├─ Is this an interactive element (spinner, trend, collapse)?
|
||||
│ ├─ YES → Use global CSS (patterns/interactive.css)
|
||||
│ └─ NO → Continue to next question
|
||||
│
|
||||
├─ Is this truly unique to this component (Chart.js canvas, complex state styling)?
|
||||
│ ├─ YES → Scoped CSS is OK (keep it minimal <50 lines)
|
||||
│ └─ NO → Extract to global pattern
|
||||
│
|
||||
└─ Still unsure? Ask in #frontend-css channel

## When to Use Global CSS
|
||||
|
||||
### ✅ Use Global CSS For:
|
||||
|
||||
#### 1. **Repeated Patterns (Used in 2+ components)**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Duplicate in every component -->
|
||||
<style scoped>
|
||||
.my-card {
|
||||
background: var(--color-bg);
|
||||
border: 1px solid var(--color-border);
|
||||
border-radius: var(--radius-md);
|
||||
padding: var(--space-lg);
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use global pattern -->
|
||||
<template>
|
||||
<div class="card">
|
||||
<div class="card-body">Content</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No styles needed! */
|
||||
</style>
|
||||
```
|
||||
|
||||
#### 2. **Form Elements**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Custom form styles -->
|
||||
<style scoped>
|
||||
.field {
|
||||
margin-bottom: 1.5rem;
|
||||
}
|
||||
.field-label {
|
||||
font-weight: 600;
|
||||
color: #333;
|
||||
}
|
||||
.field-input {
|
||||
padding: 0.5rem 1rem;
|
||||
border: 1px solid #ddd;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use forms.css -->
|
||||
<template>
|
||||
<div class="form-group">
|
||||
<label class="form-label">Username</label>
|
||||
<input class="form-input" />
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No form styles! All in forms.css */
|
||||
</style>
|
||||
```
|
||||
|
||||
#### 3. **Buttons**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Custom button -->
|
||||
<style scoped>
|
||||
.my-button {
|
||||
background: #2563eb;
|
||||
color: white;
|
||||
padding: 0.5rem 1rem;
|
||||
border-radius: 0.375rem;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use buttons.css -->
|
||||
<template>
|
||||
<button class="btn btn-primary">Click Me</button>
|
||||
</template>
|
||||
```
|
||||
|
||||
#### 4. **Card Components**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Custom card styling -->
|
||||
<style scoped>
|
||||
.metric-container {
|
||||
background: white;
|
||||
border: 1px solid #e5e7eb;
|
||||
border-radius: 0.5rem;
|
||||
padding: 1.5rem;
|
||||
}
|
||||
.metric-number {
|
||||
font-size: 2rem;
|
||||
font-weight: 700;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use cards.css patterns -->
|
||||
<template>
|
||||
<div class="metric-card">
|
||||
<div class="metric-value">$10,500</div>
|
||||
<div class="metric-label">Revenue</div>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
#### 5. **Dashboard Patterns**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Custom page header -->
|
||||
<style scoped>
|
||||
.page-heading {
|
||||
text-align: center;
|
||||
margin-bottom: 2rem;
|
||||
}
|
||||
.page-heading h1 {
|
||||
font-size: 2rem;
|
||||
font-weight: bold;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use dashboard.css -->
|
||||
<template>
|
||||
<header class="page-header">
|
||||
<h1 class="page-title">Dashboard</h1>
|
||||
<p class="page-subtitle">Overview</p>
|
||||
</header>
|
||||
</template>
|
||||
```
|
||||
|
||||
#### 6. **Utility Classes**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Custom utility styles -->
|
||||
<style scoped>
|
||||
.flex-center {
|
||||
display: flex;
|
||||
align-items: center;
|
||||
justify-content: center;
|
||||
}
|
||||
.text-green {
|
||||
color: #059669;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use utility classes -->
|
||||
<template>
|
||||
<div class="flex items-center justify-center">
|
||||
<span class="text-success">Success!</span>
|
||||
</div>
|
||||
</template>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## When to Use Scoped CSS
|
||||
|
||||
### ✅ Scoped CSS is OK For:
|
||||
|
||||
#### 1. **Component-Specific Layout (Not Reusable)**
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<div class="dual-chart-layout">
|
||||
<div class="chart-left">
|
||||
<canvas ref="chart1"></canvas>
|
||||
</div>
|
||||
<div class="chart-right">
|
||||
<canvas ref="chart2"></canvas>
|
||||
</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* Component-specific layout that won't be reused */
|
||||
.dual-chart-layout {
|
||||
display: grid;
|
||||
grid-template-columns: 1fr 1fr;
|
||||
gap: var(--space-md);
|
||||
}
|
||||
|
||||
.chart-left,
|
||||
.chart-right {
|
||||
position: relative;
|
||||
height: 300px;
|
||||
}
|
||||
|
||||
@media (max-width: 768px) {
|
||||
.dual-chart-layout {
|
||||
grid-template-columns: 1fr;
|
||||
}
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's OK:** This layout is unique to this specific dual-chart component and won't be used elsewhere.
|
||||
|
||||
#### 2. **Third-Party Library Integration (Chart.js, etc.)**
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<div class="chart-wrapper">
|
||||
<canvas ref="chartCanvas" class="chart-canvas"></canvas>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* Chart.js requires specific canvas sizing */
|
||||
.chart-wrapper {
|
||||
position: relative;
|
||||
height: 100%;
|
||||
width: 100%;
|
||||
}
|
||||
|
||||
.chart-canvas {
|
||||
width: 100% !important;
|
||||
height: 100% !important;
|
||||
display: block;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's OK:** Chart.js has specific requirements that are component-specific and not reusable patterns.
|
||||
|
||||
#### 3. **Complex Component State Styling**
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<div class="data-visualizer" :class="visualizationMode">
|
||||
<!-- Complex visualization with multiple states -->
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* Complex state-dependent styling unique to this component */
|
||||
.data-visualizer.mode-heatmap .cell {
|
||||
transition: background-color 0.3s ease;
|
||||
}
|
||||
|
||||
.data-visualizer.mode-heatmap .cell.heat-low {
|
||||
background: #dcfce7;
|
||||
}
|
||||
|
||||
.data-visualizer.mode-heatmap .cell.heat-high {
|
||||
background: #fecaca;
|
||||
}
|
||||
|
||||
.data-visualizer.mode-chart {
|
||||
display: flex;
|
||||
flex-direction: column;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's OK:** This state machine is unique to this visualization component.
|
||||
|
||||
#### 4. **Print Styles (Component-Specific)**
|
||||
|
||||
```vue
|
||||
<style scoped>
|
||||
@media print {
|
||||
.no-print-action {
|
||||
display: none !important;
|
||||
}
|
||||
|
||||
.invoice-table {
|
||||
page-break-inside: avoid;
|
||||
}
|
||||
|
||||
.invoice-header {
|
||||
page-break-after: avoid;
|
||||
}
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's OK:** Print styles for specific components that have unique printing requirements.
|
||||
|
||||
---
|
||||
|
||||
## Anti-Patterns
|
||||
|
||||
### ❌ NEVER Do These Things
|
||||
|
||||
#### 1. **Using `:deep()` for PrimeVue**
|
||||
|
||||
```vue
|
||||
<!-- ❌ ABSOLUTELY FORBIDDEN -->
|
||||
<style scoped>
|
||||
:deep(.p-inputtext) {
|
||||
border: 2px solid #3b82f6 !important;
|
||||
padding: 1rem !important;
|
||||
}
|
||||
|
||||
:deep(.p-datatable .p-datatable-thead) {
|
||||
background: #f3f4f6 !important;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's bad:**
|
||||
- Creates specificity issues
|
||||
- Overrides break easily
|
||||
- Not maintainable
|
||||
- Causes cascading problems
|
||||
|
||||
**✅ Correct approach:**
|
||||
All PrimeVue styling goes in `src/assets/css/vendor/primevue-overrides.css`:
|
||||
|
||||
```css
|
||||
/* vendor/primevue-overrides.css */
|
||||
.p-inputtext {
|
||||
border: 2px solid var(--color-primary);
|
||||
padding: 1rem;
|
||||
}
|
||||
|
||||
.p-datatable .p-datatable-thead {
|
||||
background: var(--color-bg-secondary);
|
||||
}
|
||||
```
|
||||
|
||||
#### 2. **Hardcoding Colors/Sizes**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Hardcoded values -->
|
||||
<style scoped>
|
||||
.card {
|
||||
background: #ffffff;
|
||||
border: 1px solid #e5e7eb;
|
||||
border-radius: 8px;
|
||||
padding: 24px;
|
||||
color: #111827;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Design tokens -->
|
||||
<style scoped>
|
||||
.custom-layout {
|
||||
background: var(--color-bg);
|
||||
border: 1px solid var(--color-border);
|
||||
border-radius: var(--radius-md);
|
||||
padding: var(--space-lg);
|
||||
color: var(--color-text);
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
#### 3. **Duplicating Existing Patterns**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Recreating button styles -->
|
||||
<style scoped>
|
||||
.submit-button {
|
||||
background: #2563eb;
|
||||
color: white;
|
||||
padding: 0.5rem 1rem;
|
||||
border: none;
|
||||
border-radius: 0.375rem;
|
||||
cursor: pointer;
|
||||
}
|
||||
|
||||
.submit-button:hover {
|
||||
background: #1d4ed8;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use existing pattern -->
|
||||
<template>
|
||||
<button class="btn btn-primary">Submit</button>
|
||||
</template>
|
||||
```
|
||||
|
||||
#### 4. **Using `!important` in Scoped Styles**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD -->
|
||||
<style scoped>
|
||||
.my-element {
|
||||
color: red !important;
|
||||
font-size: 16px !important;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Only use !important for vendor overrides in global CSS -->
|
||||
<style scoped>
|
||||
.my-element {
|
||||
color: var(--color-error);
|
||||
font-size: var(--text-base);
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Exception:** `!important` is allowed in:
|
||||
- `vendor/primevue-overrides.css` (to override PrimeVue)
|
||||
- Print styles (`@media print`)
|
||||
- Third-party library overrides (documented reason required)
|
||||
|
||||
#### 5. **Creating Custom Form/Button Base Styles**
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Custom base styles -->
|
||||
<style scoped>
|
||||
.input-field {
|
||||
width: 100%;
|
||||
padding: 0.5rem 1rem;
|
||||
border: 1px solid #ddd;
|
||||
border-radius: 0.375rem;
|
||||
}
|
||||
|
||||
.primary-btn {
|
||||
background: #2563eb;
|
||||
color: white;
|
||||
padding: 0.5rem 1rem;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use global patterns -->
|
||||
<template>
|
||||
<input class="form-input" />
|
||||
<button class="btn btn-primary">Click</button>
|
||||
</template>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Code Review Checklist
|
||||
|
||||
### Before Submitting PR
|
||||
|
||||
- [ ] **No duplicate patterns** - Checked `docs/CSS_PATTERNS.md` first
|
||||
- [ ] **No `:deep()` in components** - PrimeVue styles in `vendor/primevue-overrides.css`
|
||||
- [ ] **Design tokens used** - No hardcoded colors, sizes, or spacing
|
||||
- [ ] **No `!important` in scoped styles** - Except documented exceptions
|
||||
- [ ] **Scoped styles < 50 lines** - If more, consider extracting to global
|
||||
- [ ] **No form/button/card base styles** - Use existing global patterns
|
||||
- [ ] **Responsive tested** - Works on mobile (375px), tablet (768px), desktop (1920px)
|
||||
- [ ] **Build successful** - `npm run build` passes
|
||||
- [ ] **Playwright tests pass** - `npm run test:e2e` passes
|
||||
- [ ] **CSS is necessary** - Not adding CSS just because "it looks different"
|
||||
|
||||
### Review Questions
|
||||
|
||||
**For Scoped CSS:**
|
||||
1. Is this styling truly unique to this component?
|
||||
2. Could this be used in 2+ places? → Make it global
|
||||
3. Can this use existing patterns? → Use global CSS
|
||||
4. Is this < 50 lines? → If not, extract to global
|
||||
5. Does it have a documented reason? → Add comment
|
||||
|
||||
**For Global CSS:**
|
||||
1. Is this pattern used in 2+ places?
|
||||
2. Will this be reused in the future?
|
||||
3. Does it fit existing pattern categories?
|
||||
4. Is it generic enough for reuse?
|
||||

## Examples
|
||||
|
||||
### ✅ Example #1: Good Use of Global CSS
|
||||
|
||||
```vue
|
||||
<!-- Component: MetricCard.vue -->
|
||||
<template>
|
||||
<div class="metric-card card-hover">
|
||||
<div class="metric-header">
|
||||
<div class="metric-icon bg-primary-light text-primary">
|
||||
<i class="pi pi-chart-bar"></i>
|
||||
</div>
|
||||
<div class="metric-label">Sales</div>
|
||||
</div>
|
||||
<div class="metric-value">$10,500</div>
|
||||
<div class="trend trend-up">
|
||||
<i class="pi pi-arrow-up trend-icon"></i>
|
||||
+12.5%
|
||||
</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No styles needed! All from global CSS:
|
||||
* - metric-card (cards.css)
|
||||
* - metric-header, metric-icon, metric-value, metric-label (cards.css)
|
||||
* - trend, trend-up, trend-icon (patterns/interactive.css)
|
||||
* - bg-primary-light, text-primary (utilities/colors.css)
|
||||
* - card-hover (patterns/interactive.css)
|
||||
*/
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's good:**
|
||||
- Zero duplicate CSS
|
||||
- Uses established patterns
|
||||
- Maintainable
|
||||
- Consistent with other cards
|
||||
|
||||

|
||||
|
||||
### ✅ Example #2: Good Use of Scoped CSS
|
||||
|
||||
```vue
|
||||
<!-- Component: TreasuryDualCard.vue -->
|
||||
<template>
|
||||
<div class="metric-card">
|
||||
<div class="metric-label">Treasury</div>
|
||||
|
||||
<!-- UNIQUE: Side-by-side charts (not used elsewhere) -->
|
||||
<div class="dual-chart-container">
|
||||
<div class="chart-section">
|
||||
<div class="chart-header">
|
||||
<span class="chart-title">Bank</span>
|
||||
<span class="chart-value">{{ bankBalance }}</span>
|
||||
</div>
|
||||
<canvas ref="bankChart" class="chart-canvas"></canvas>
|
||||
</div>
|
||||
|
||||
<div class="chart-section">
|
||||
<div class="chart-header">
|
||||
<span class="chart-title">Cash</span>
|
||||
<span class="chart-value">{{ cashBalance }}</span>
|
||||
</div>
|
||||
<canvas ref="cashChart" class="chart-canvas"></canvas>
|
||||
</div>
|
||||
</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* Component-specific layout: Two charts side-by-side */
|
||||
.dual-chart-container {
|
||||
display: grid;
|
||||
grid-template-columns: 1fr 1fr;
|
||||
gap: var(--space-lg);
|
||||
margin-top: var(--space-md);
|
||||
}
|
||||
|
||||
.chart-section {
|
||||
min-height: 200px;
|
||||
}
|
||||
|
||||
.chart-header {
|
||||
display: flex;
|
||||
justify-content: space-between;
|
||||
align-items: baseline;
|
||||
margin-bottom: var(--space-sm);
|
||||
}
|
||||
|
||||
.chart-title {
|
||||
font-size: var(--text-sm);
|
||||
font-weight: var(--font-medium);
|
||||
color: var(--color-text-secondary);
|
||||
text-transform: uppercase;
|
||||
}
|
||||
|
||||
.chart-value {
|
||||
font-size: var(--text-lg);
|
||||
font-weight: var(--font-semibold);
|
||||
font-family: var(--font-mono, monospace);
|
||||
}
|
||||
|
||||
/* Chart.js canvas sizing (library-specific requirement) */
|
||||
.chart-canvas {
|
||||
width: 100% !important;
|
||||
height: 100% !important;
|
||||
}
|
||||
|
||||
@media (max-width: 768px) {
|
||||
.dual-chart-container {
|
||||
grid-template-columns: 1fr;
|
||||
}
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Why it's good:**
|
||||
- Unique layout specific to this component
|
||||
- Uses design tokens
|
||||
- Chart.js integration requires specific CSS
|
||||
- Responsive
|
||||
- Well-commented
|
||||

||||
### ❌ Example #3: Bad - Duplicate Pattern
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: ClientiBalanceCard.vue -->
|
||||
<template>
|
||||
<div class="balance-card">
|
||||
<div class="card-title">Clients Balance</div>
|
||||
<div class="balance-amount">$50,000</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
.balance-card {
|
||||
background: var(--color-bg);
|
||||
border: 1px solid var(--color-border);
|
||||
border-radius: var(--card-radius);
|
||||
padding: var(--space-lg);
|
||||
/* Duplicating card pattern from cards.css */
|
||||
}
|
||||
|
||||
.card-title {
|
||||
font-size: var(--text-sm);
|
||||
font-weight: var(--font-medium);
|
||||
color: var(--color-text-secondary);
|
||||
text-transform: uppercase;
|
||||
/* Duplicating metric-label from cards.css */
|
||||
}
|
||||
|
||||
.balance-amount {
|
||||
font-size: var(--text-2xl);
|
||||
font-weight: var(--font-bold);
|
||||
font-family: var(--font-mono);
|
||||
/* Duplicating metric-value from cards.css */
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Use global patterns -->
|
||||
<template>
|
||||
<div class="metric-card">
|
||||
<div class="metric-label">Clients Balance</div>
|
||||
<div class="metric-value">$50,000</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No styles needed! */
|
||||
</style>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
### 1. **Check Pattern Library First**
|
||||
|
||||
Before writing ANY CSS, check:
|
||||
1. [CSS Patterns Library](./CSS_PATTERNS.md)
|
||||
2. `src/assets/css/` directories
|
||||
3. Ask yourself: "Has this been done before?"
|
||||
|
||||
### 2. **Use Design Tokens**
|
||||
|
||||
```vue
|
||||
<!-- ✅ GOOD -->
|
||||
<style scoped>
|
||||
.custom-element {
|
||||
color: var(--color-text);
|
||||
background: var(--color-bg);
|
||||
padding: var(--space-md);
|
||||
border-radius: var(--radius-md);
|
||||
font-size: var(--text-base);
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ❌ BAD -->
|
||||
<style scoped>
|
||||
.custom-element {
|
||||
color: #111827;
|
||||
background: #ffffff;
|
||||
padding: 1rem;
|
||||
border-radius: 0.375rem;
|
||||
font-size: 16px;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
### 3. **Keep Scoped CSS Minimal**
|
||||
|
||||
**Rule of thumb:** If scoped styles > 50 lines, extract to global pattern.
|
||||
|
||||
```vue
|
||||
<!-- ❌ BAD: Too much scoped CSS (>50 lines) -->
|
||||
<style scoped>
|
||||
.container {
|
||||
/* ... 20 lines ... */
|
||||
}
|
||||
.header {
|
||||
/* ... 15 lines ... */
|
||||
}
|
||||
.body {
|
||||
/* ... 20 lines ... */
|
||||
}
|
||||
/* Total: 55 lines - extract to global! */
|
||||
</style>
|
||||
|
||||
<!-- ✅ GOOD: Minimal scoped CSS -->
|
||||
<style scoped>
|
||||
/* Only component-specific layout (15 lines) */
|
||||
.chart-grid {
|
||||
display: grid;
|
||||
grid-template-columns: repeat(auto-fit, minmax(300px, 1fr));
|
||||
gap: var(--space-lg);
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
### 4. **Document Scoped CSS Rationale**
|
||||
|
||||
```vue
|
||||
<style scoped>
|
||||
/**
|
||||
* Component-specific layout for dual sparkline charts.
|
||||
* This layout is unique to CashFlowMetricCard and won't be reused.
|
||||
*
|
||||
* Reason for scoped CSS: Dual-chart layout with synchronized tooltips
|
||||
* requires component-specific positioning that isn't a general pattern.
|
||||
*/
|
||||
.dual-chart-layout {
|
||||
display: grid;
|
||||
grid-template-columns: 1fr 1fr;
|
||||
gap: var(--space-md);
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
### 5. **Responsive Design**
|
||||
|
||||
Use global responsive patterns when possible:
|
||||
|
||||
```vue
|
||||
<!-- ✅ GOOD: Use global responsive utilities -->
|
||||
<template>
|
||||
<div class="flex flex-col md:flex-row gap-md">
|
||||
<div class="w-full md:w-1/2">Left</div>
|
||||
<div class="w-full md:w-1/2">Right</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<!-- ⚠️ OK: Component-specific breakpoints if truly unique -->
|
||||
<style scoped>
|
||||
.custom-grid {
|
||||
display: grid;
|
||||
grid-template-columns: 1fr 1fr 1fr;
|
||||
}
|
||||
|
||||
@media (max-width: 1024px) {
|
||||
.custom-grid {
|
||||
grid-template-columns: 1fr 1fr;
|
||||
}
|
||||
}
|
||||
|
||||
@media (max-width: 768px) {
|
||||
.custom-grid {
|
||||
grid-template-columns: 1fr;
|
||||
}
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Migration Guide
|
||||
|
||||
### Migrating Existing Components
|
||||
|
||||
**Step 1:** Identify duplicate patterns
|
||||
```bash
|
||||
# Search for common patterns
|
||||
grep -r "background: var(--color-bg)" src/components/
|
||||
grep -r "border: 1px solid" src/components/
|
||||
grep -r ":deep(.p-" src/components/
|
||||
```
|
||||
|
||||
**Step 2:** Check Pattern Library
|
||||
- Review `docs/CSS_PATTERNS.md`
|
||||
- Find matching global patterns
|
||||
|
||||
**Step 3:** Replace with Global CSS
|
||||
```vue
|
||||
<!-- BEFORE -->
|
||||
<style scoped>
|
||||
.my-card {
|
||||
background: var(--color-bg);
|
||||
border: 1px solid var(--color-border);
|
||||
padding: var(--space-lg);
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- AFTER -->
|
||||
<template>
|
||||
<div class="card">
|
||||
<div class="card-body">Content</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No styles needed! */
|
||||
</style>
|
||||
```
|
||||
|
||||
**Step 4:** Test
|
||||
- Build: `npm run build`
|
||||
- E2E tests: `npm run test:e2e`
|
||||
- Visual inspection on all breakpoints

## Overview
|
||||
|
||||
This document provides a comprehensive reference to all CSS patterns available in the ROA2WEB frontend application. All patterns are production-ready, tested, and follow our design system.
|
||||
|
||||
### Key Principles
|
||||
|
||||
- ✅ **Use global patterns first** - Check this library before writing custom CSS
|
||||
- ✅ **Design tokens** - Use CSS variables (`var(--color-primary)`) not hardcoded values
|
||||
- ✅ **Responsive by default** - All patterns work on mobile
|
||||
- ✅ **Accessibility** - WCAG 2.1 AA compliant
|
||||
- ❌ **No duplication** - Never recreate existing patterns
|
||||

|
||||
|
||||
## Card Patterns
|
||||
|
||||
### Basic Card
|
||||
|
||||
Standard card with optional header, body, and footer sections.
|
||||
|
||||
```html
|
||||
<div class="card">
|
||||
<div class="card-header">
|
||||
<h3>Card Title</h3>
|
||||
</div>
|
||||
<div class="card-body">
|
||||
<p>Card content goes here</p>
|
||||
</div>
|
||||
<div class="card-footer">
|
||||
<button class="btn btn-primary">Action</button>
|
||||
</div>
|
||||
</div>
|
||||
```
|
||||
|
||||
**Variants:**
|
||||
- `.card-compact` - Reduced padding
|
||||
- `.card-minimal` - No border/shadow
|
||||
- `.card-elevated` - Higher shadow with hover lift
|
||||
- `.card-hover` - Hover effect with border color change
|
||||
|
||||
**Use Cases:**
|
||||
- Content containers
|
||||
- Form wrappers
|
||||
- Information blocks
|
||||
|
||||

|
||||
|
||||
### Metric Card

||||
<Column field="name" header="Name" sortable></Column>
|
||||
<Column field="email" header="Email"></Column>
|
||||
<Column field="status" header="Status">
|
||||
<template #body="slotProps">
|
||||
<span :class="getStatusClass(slotProps.data.status)">
|
||||
{{ slotProps.data.status }}
|
||||
</span>
|
||||
</template>
|
||||
</Column>
|
||||
</DataTable>
|
||||
```
|
||||
|
||||
**Global Row Classes (App.vue):**

||||

/* = rgba(37, 99, 235, 0.1) */
|
||||
|
||||
border-color: rgba(var(--color-success-rgb), 0.5);
|
||||
/* = rgba(5, 150, 105, 0.5) */
|
||||
```
|
||||
|
||||
### Status Background Colors (10% opacity)
|
||||
|
||||
| Token | Value | Use Case |
|
||||
|-------|-------|----------|
|
||||
| `--color-success-bg` | rgba(5, 150, 105, 0.1) | Success alerts background |
|
||||
| `--color-warning-bg` | rgba(217, 119, 6, 0.1) | Warning alerts background |
|
||||
| `--color-error-bg` | rgba(220, 38, 38, 0.1) | Error alerts background |
|
||||
| `--color-info-bg` | rgba(8, 145, 178, 0.1) | Info alerts background |
|
||||
|
||||
### Monospace Font
|
||||
|
||||
```css
|
||||
/* For numbers, code, metrics */
|
||||
font-family: var(--font-mono);
|
||||
/* = 'SF Mono', Consolas, 'Liberation Mono', Menlo, Courier, monospace */
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Compatibility Aliases
|
||||
|
||||
For backwards compatibility with existing code:
|
||||
|
||||
| Alias | Maps To |
|
||||
|-------|---------|
|
||||
| `--primary-color` | `var(--color-primary)` |
|
||||
| `--primary-color-dark` | `var(--color-primary-dark)` |
|
||||
| `--text-color` | `var(--color-text)` |
|
||||
| `--text-color-secondary` | `var(--color-text-secondary)` |
|
||||
|
||||
---
|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Complete Button
|
||||
|
||||
```css
|
||||
.btn-primary {
|
||||
/* Typography */
|
||||
font-size: var(--text-sm);
|
||||
font-weight: var(--font-medium);
|
||||
line-height: var(--leading-normal);
|
||||
|
||||
/* Spacing */
|
||||
padding: var(--space-sm) var(--space-md);
|
||||
gap: var(--space-xs);
|
||||
|
||||
/* Colors */
|
||||
background: var(--color-primary);
|
||||
color: var(--color-text-inverse);
|
||||
border: 1px solid var(--color-primary);
|
||||
|
||||
/* Visual */
|
||||
border-radius: var(--radius-md);
|
||||
box-shadow: var(--shadow-sm);
|
||||
|
||||
/* Interaction */
|
||||
transition: all var(--transition-fast);
|
||||
}
|
||||
|
||||
.btn-primary:hover {
|
||||
background: var(--color-primary-dark);
|
||||
box-shadow: var(--shadow-md);
|
||||
transform: translateY(var(--hover-lift));
|
||||
}
|
||||
```
|
||||
|
||||
### Complete Card
|
||||
|
||||
```css
|
||||
.card {
|
||||
/* Layout */
|
||||
padding: var(--card-padding);
|
||||
min-height: var(--card-min-height);
|
||||
display: flex;
|
||||
flex-direction: column;
|
||||
gap: var(--card-gap);
|
||||
|
||||
/* Colors */
|
||||
background: var(--color-bg);
|
||||
border: 1px solid var(--color-border);
|
||||
color: var(--color-text);
|
||||
|
||||
/* Visual */
|
||||
border-radius: var(--card-radius);
|
||||
box-shadow: var(--shadow-sm);
|
||||
|
||||
/* Interaction */
|
||||
transition: all var(--transition-fast);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Best Practices
|
||||
|
||||
### ✅ Do
|
||||
|
||||
```css
|
||||
/* Use tokens for all values */
|
||||
.element {
|
||||
color: var(--color-text);
|
||||
font-size: var(--text-base);
|
||||
padding: var(--space-md);
|
||||
border-radius: var(--radius-md);
|
||||
}
|
||||
|
||||
/* Combine tokens */
|
||||
.card-padding {
|
||||
padding: var(--space-lg) var(--space-xl);
|
||||
}
|
||||
```
|
||||
|
||||
### ❌ Don't
|
||||
|
||||
```css
|
||||
/* Don't hardcode values */
|
||||
.element {
|
||||
color: #111827; /* Use var(--color-text) */
|
||||
font-size: 16px; /* Use var(--text-base) */
|
||||
padding: 16px; /* Use var(--space-md) */
|
||||
border-radius: 8px; /* Use var(--radius-md) */
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Dark Mode (Future)
|
||||
|
||||
Dark mode tokens are defined in `variables.css` using `@media (prefers-color-scheme: dark)`. When enabled, tokens automatically switch to dark variants.

# CSS System Onboarding Guide
|
||||
|
||||
**Welcome to ROA2WEB CSS Architecture!**
|
||||
**Version:** 2.0.0 | **Updated:** 2025-11-19
|
||||
|
||||
---
|
||||
|
||||
## Quick Start (5 Minutes)
|
||||
|
||||
### 1. Understand the Structure
|
||||
|
||||
```
|
||||
src/assets/css/
|
||||
├── core/ # Design tokens (colors, spacing, typography)
|
||||
├── components/ # Reusable UI (buttons, forms, cards)
|
||||
├── patterns/ # Interactive patterns (spinners, trends)
|
||||
├── layout/ # Page structure (containers, grid)
|
||||
├── utilities/ # Utility classes (colors, spacing, flex)
|
||||
└── vendor/ # PrimeVue overrides
|
||||
```
|
||||
|
||||
### 2. Golden Rules
|
||||
|
||||
```
|
||||
✅ Use global patterns first (check docs/CSS_PATTERNS.md)
|
||||
✅ Use design tokens (var(--color-primary) not #2563eb)
|
||||
❌ Never use :deep() in components (PrimeVue → vendor/)
|
||||
❌ Never duplicate CSS (write once, use everywhere)
|
||||
❌ Never hardcode values (tokens for everything)
|
||||
```
|
||||
|
||||
### 3. Your First Component (10 Minutes)
|
||||
|
||||
**Before writing ANY CSS:**
|
||||
1. Check [CSS_PATTERNS.md](./CSS_PATTERNS.md)
|
||||
2. Search existing code: `grep -r "pattern-name" src/assets/css/`
|
||||
3. If it exists → use it. If not → continue reading.
|
||||
|
||||
**Example: Creating a Card**
|
||||
|
||||
```vue
|
||||
<!-- ❌ DON'T DO THIS -->
|
||||
<template>
|
||||
<div class="my-card">Content</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
.my-card {
|
||||
background: white;
|
||||
border: 1px solid #e5e7eb;
|
||||
padding: 24px;
|
||||
border-radius: 8px;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- ✅ DO THIS -->
|
||||
<template>
|
||||
<div class="card">
|
||||
<div class="card-body">Content</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No styles needed! */
|
||||
</style>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Decision Tree (30 Seconds)
|
||||
|
||||
```
|
||||
Need to style something?
|
||||
↓
|
||||
Does this pattern exist? → YES → Use global CSS
|
||||
↓ NO
|
||||
Is this a form/button/card? → YES → Use global CSS (forms.css, buttons.css, cards.css)
|
||||
↓ NO
|
||||
Is this PrimeVue? → YES → Edit vendor/primevue-overrides.css
|
||||
↓ NO
|
||||
Truly component-specific? → YES → Scoped CSS OK (keep < 50 lines)
|
||||
↓ NO
|
||||
Extract to global pattern
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Common Tasks
|
||||
|
||||
### Task: Add a New Form
|
||||
|
||||
**Template:** [docs/FORM_TEMPLATE.md](./FORM_TEMPLATE.md)
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<form @submit.prevent="handleSubmit" class="form">
|
||||
<div class="form-group">
|
||||
<label for="field" class="form-label required">Label</label>
|
||||
<input id="field" v-model="data.field" class="form-input" />
|
||||
<span v-if="errors.field" class="form-error">{{ errors.field }}</span>
|
||||
</div>
|
||||
|
||||
<div class="form-actions">
|
||||
<button type="button" class="btn btn-secondary">Cancel</button>
|
||||
<button type="submit" class="btn btn-primary">Submit</button>
|
||||
</div>
|
||||
</form>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No form styles needed! All in forms.css */
|
||||
</style>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Task: Create a Dashboard Card
|
||||
|
||||
**Pattern:** [CSS_PATTERNS.md#metric-card](./CSS_PATTERNS.md#metric-card)
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<div class="metric-card card-hover">
|
||||
<div class="metric-header">
|
||||
<div class="metric-icon bg-primary-light text-primary">
|
||||
<i class="pi pi-chart-bar"></i>
|
||||
</div>
|
||||
<div class="metric-label">Sales</div>
|
||||
</div>
|
||||
<div class="metric-value">$10,500</div>
|
||||
<div class="trend trend-up">
|
||||
<i class="pi pi-arrow-up trend-icon"></i>
|
||||
+12.5%
|
||||
</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/* No styles! Global patterns handle everything */
|
||||
</style>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Task: Style a PrimeVue Component
|
||||
|
||||
**Never do this:**
|
||||
```vue
|
||||
<!-- ❌ NEVER -->
|
||||
<style scoped>
|
||||
:deep(.p-inputtext) {
|
||||
border: 2px solid blue !important;
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||
**Always do this:**
|
||||
```css
|
||||
/* ✅ Edit src/assets/css/vendor/primevue-overrides.css */
|
||||
.p-inputtext {
|
||||
border: 2px solid var(--color-primary);
|
||||
padding: var(--space-md);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### Task: Add Custom Component Layout
|
||||
|
||||
**Only if truly unique:**
|
||||
|
||||
```vue
|
||||
<template>
|
||||
<div class="dual-chart-layout">
|
||||
<div class="chart-left">
|
||||
<canvas ref="chart1"></canvas>
|
||||
</div>
|
||||
<div class="chart-right">
|
||||
<canvas ref="chart2"></canvas>
|
||||
</div>
|
||||
</div>
|
||||
</template>
|
||||
|
||||
<style scoped>
|
||||
/**
|
||||
* Component-specific layout: Side-by-side charts
|
||||
* Reason: This layout is unique to this component and won't be reused
|
||||
*/
|
||||
.dual-chart-layout {
|
||||
display: grid;
|
||||
grid-template-columns: 1fr 1fr;
|
||||
gap: var(--space-md);
|
||||
}
|
||||
|
||||
@media (max-width: 768px) {
|
||||
.dual-chart-layout {
|
||||
grid-template-columns: 1fr;
|
||||
}
|
||||
}
|
||||
</style>
|
||||
```
|
||||
|
||||

## Common Mistakes & Fixes
|
||||
|
||||
### ❌ Mistake #1: Not checking patterns first
|
||||
|
||||
```vue
|
||||
<!-- Wrong: Recreating button -->
|
||||
<style scoped>
|
||||
.submit-btn {
|
||||
background: #2563eb;
|
||||
color: white;
|
||||
padding: 0.5rem 1rem;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- Correct: Use existing -->
|
||||
<button class="btn btn-primary">Submit</button>
|
||||
```
|
||||
|
||||
### ❌ Mistake #2: Hardcoded values
|
||||
|
||||
```css
|
||||
/* Wrong */
|
||||
color: #111827;
|
||||
padding: 16px;
|
||||
border-radius: 8px;
|
||||
|
||||
/* Correct */
|
||||
color: var(--color-text);
|
||||
padding: var(--space-md);
|
||||
border-radius: var(--radius-md);
|
||||
```
|
||||
|
||||
### ❌ Mistake #3: Using :deep() for PrimeVue
|
||||
|
||||
```vue
|
||||
<!-- Wrong: In component -->
|
||||
<style scoped>
|
||||
:deep(.p-dropdown) {
|
||||
border: 2px solid blue;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- Correct: In vendor/primevue-overrides.css -->
|
||||
```
|
||||

# Styling Best Practices & Guidelines
|
||||
|
||||
**Version:** 2.0.0
|
||||
**Last Updated:** 2025-11-19
|
||||
**Status:** ✅ Complete
|
||||
|
||||
---
|
||||
|
||||
## Quick Reference
|
||||
|
||||
### Golden Rules
|
||||
|
||||
1. ✅ **Use global patterns first** - Check [CSS_PATTERNS.md](./CSS_PATTERNS.md)
|
||||
2. ✅ **Use design tokens** - `var(--color-primary)` not `#2563eb`
|
||||
3. ❌ **No `:deep()` in components** - PrimeVue styles in `vendor/primevue-overrides.css`
|
||||
4. ❌ **No duplication** - Write CSS once, use everywhere
|
||||
5. ❌ **No hardcoded values** - Use tokens for all values
|
||||
|
||||

|
||||
|
||||
## Design Token Usage
|
||||
|
||||
### Colors
|
||||
```css
|
||||
/* ✅ GOOD */
|
||||
color: var(--color-primary);
|
||||
background: var(--color-bg);
|
||||
border-color: var(--color-border);
|
||||
|
||||
/* ❌ BAD */
|
||||
color: #2563eb;
|
||||
background: #ffffff;
|
||||
border-color: #e5e7eb;
|
||||
```
|
||||
|
||||
### Spacing
|
||||
```css
|
||||
/* ✅ GOOD */
|
||||
padding: var(--space-md);
|
||||
margin: var(--space-lg);
|
||||
gap: var(--space-sm);
|
||||
|
||||
/* ❌ BAD */
|
||||
padding: 16px;
|
||||
margin: 24px;
|
||||
gap: 8px;
|
||||
```
|
||||
|
||||
### Typography
|
||||
```css
|
||||
/* ✅ GOOD */
|
||||
font-size: var(--text-base);
|
||||
font-weight: var(--font-semibold);
|
||||
line-height: var(--leading-normal);
|
||||
|
||||
/* ❌ BAD */
|
||||
font-size: 16px;
|
||||
font-weight: 600;
|
||||
line-height: 1.5;
|
||||
```

## Naming Conventions
|
||||
|
||||
### Classes
|
||||
|
||||
```css
|
||||
/* Component classes: .component-name */
|
||||
.card { }
|
||||
.btn { }
|
||||
.form-input { }
|
||||
|
||||
/* Variant classes: .component-variant */
|
||||
.btn-primary { }
|
||||
.btn-secondary { }
|
||||
.card-elevated { }
|
||||
|
||||
/* State classes: .state */
|
||||
.active { }
|
||||
.disabled { }
|
||||
.invalid { }
|
||||
|
||||
/* Utility classes: .utility-value */
|
||||
.text-center { }
|
||||
.flex { }
|
||||
.mt-lg { }
|
||||
```
|
||||
|
||||
### BEM (When Needed)
|
||||
|
||||
```css
|
||||
/* Block__Element--Modifier */
|
||||
.metric-card { } /* Block */
|
||||
.metric-card__header { } /* Element */
|
||||
.metric-card--compact { } /* Modifier */
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Performance
|
||||
|
||||
### CSS Bundle Optimization
|
||||
|
||||
```css
|
||||
/* ✅ GOOD: Group related selectors */
|
||||
.btn,
|
||||
.btn-primary,
|
||||
.btn-secondary {
|
||||
display: inline-flex;
|
||||
align-items: center;
|
||||
}
|
||||
|
||||
/* ❌ BAD: Repeat properties */
|
||||
.btn { display: inline-flex; align-items: center; }
|
||||
.btn-primary { display: inline-flex; align-items: center; }
|
||||
.btn-secondary { display: inline-flex; align-items: center; }
|
||||
```
|
||||
|
||||
### Animations
|
||||
|
||||
```css
|
||||
/* ✅ GOOD: Use transform & opacity (GPU-accelerated) */
|
||||
.card-hover:hover {
|
||||
transform: translateY(-2px);
|
||||
opacity: 0.9;
|
||||
}
|
||||
|
||||
/* ❌ BAD: Animate layout properties */
|
||||
.card-hover:hover {
|
||||
top: -2px; /* Forces reflow */
|
||||
height: 110%; /* Forces reflow */
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Accessibility
|
||||
|
||||
### Color Contrast (WCAG 2.1 AA)
|
||||
|
||||
```css
|
||||
/* ✅ GOOD: 4.5:1 contrast ratio */
|
||||
color: var(--color-text); /* #111827 on #ffffff = 16.9:1 */
|
||||
background: var(--color-bg);
|
||||
|
||||
/* ✅ GOOD: Large text (18px+) needs 3:1 */
|
||||
.heading {
|
||||
font-size: var(--text-xl);
|
||||
color: var(--color-text-secondary); /* #6b7280 = 4.6:1 */
|
||||
}
|
||||
```
|
||||
|
||||
### Focus States
|
||||
|
||||
```css
|
||||
/* ✅ GOOD: Visible focus indicator */
|
||||
.btn:focus-visible {
|
||||
outline: 2px solid var(--color-primary);
|
||||
outline-offset: 2px;
|
||||
}
|
||||
|
||||
/* ❌ BAD: Removing focus */
|
||||
.btn:focus {
|
||||
outline: none; /* Never do this! */
|
||||
}
|
||||
```
|
||||
|
||||
### Touch Targets (Mobile)
|
||||
|
||||
```css
|
||||
/* ✅ GOOD: Minimum 44x44px */
|
||||
.btn {
|
||||
min-height: 44px;
|
||||
min-width: 44px;
|
||||
padding: var(--space-sm) var(--space-md);
|
||||
}
|
||||
```
|
||||
|
||||

## Code Review Standards
|
||||
|
||||
### CSS in PRs
|
||||
|
||||
Reviewers check for:
|
||||
|
||||
1. **No duplication** - Pattern exists in global CSS?
|
||||
2. **Design tokens** - All values use `var(--*)`?
|
||||
3. **No `:deep()`** - PrimeVue overrides in correct file?
|
||||
4. **Scoped CSS justified** - < 50 lines & documented?
|
||||
5. **Responsive** - Works on all breakpoints?
|
||||
6. **Accessible** - Focus states, contrast ratios?
|
||||
7. **Performance** - No layout thrashing animations?
|
||||
8. **Tested** - Build passes, E2E tests pass?

## Common Mistakes
|
||||
|
||||
### ❌ Mistake #1: Not Checking Pattern Library
|
||||
|
||||
```vue
|
||||
<!-- Wrong: Recreating existing pattern -->
|
||||
<style scoped>
|
||||
.my-button {
|
||||
background: var(--color-primary);
|
||||
/* ... 20 lines duplicating btn class */
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- Correct: Use existing pattern -->
|
||||
<button class="btn btn-primary">Click</button>
|
||||
```
|
||||
|
||||
### ❌ Mistake #2: Hardcoded Values
|
||||
|
||||
```css
|
||||
/* Wrong */
|
||||
padding: 16px;
|
||||
color: #2563eb;
|
||||
border-radius: 8px;
|
||||
|
||||
/* Correct */
|
||||
padding: var(--space-md);
|
||||
color: var(--color-primary);
|
||||
border-radius: var(--radius-md);
|
||||
```
|
||||
|
||||
### ❌ Mistake #3: Using `:deep()` for PrimeVue
|
||||
|
||||
```vue
|
||||
<!-- Wrong: In component -->
|
||||
<style scoped>
|
||||
:deep(.p-inputtext) {
|
||||
border: 2px solid blue !important;
|
||||
}
|
||||
</style>
|
||||
|
||||
<!-- Correct: In vendor/primevue-overrides.css -->
|
||||
```
