## 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
