## Button Accessibility
All interactive buttons include proper accessibility attributes:
### Fixed Action Buttons
Located in `templates/partials/widgets/`:
```html
<!-- Download PDF Button -->
<button id="download-button"
aria-label="{{.UI.Widgets.Download.AriaLabel}}"
data-tooltip="{{.UI.Widgets.Download.Tooltip}}">
<iconify-icon icon="catppuccin:pdf"></iconify-icon>
</button>
<!-- Print-Friendly Button -->
<button id="print-friendly-button"
aria-label="{{.UI.Widgets.Print.AriaLabel}}"
data-tooltip="{{.UI.Widgets.Print.Tooltip}}">
<iconify-icon icon="mdi:leaf"></iconify-icon>
</button>
<!-- Shortcuts Button -->
<button id="shortcuts-button"
aria-label="{{.UI.Widgets.Shortcuts.AriaLabel}}"
data-tooltip="{{.UI.Widgets.Shortcuts.Tooltip}}">
<iconify-icon icon="mdi:keyboard-outline"></iconify-icon>
</button>
```
### Mobile Menu Buttons
Located in `templates/partials/navigation/hamburger-menu.html`:
```html
<!-- All menu action buttons have aria-labels -->
<button class="menu-action-btn menu-pdf-btn"
aria-label="{{.UI.Widgets.ActionButtons.DownloadPdf}}">
<iconify-icon icon="catppuccin:pdf"></iconify-icon>
<span>{{.UI.Widgets.ActionButtons.DownloadPdf}}</span>
</button>
```
### Best Practices
1. **Icon-only buttons**: Always include `aria-label`
2. **Buttons with text**: Visible text serves as the accessible name
3. **Tooltips**: Use `data-tooltip` for visual hint, `aria-label` for screen readers
---
## Form Elements
All form inputs have proper label associations:
### Toggle Checkboxes
Desktop toggles in `templates/partials/navigation/view-controls.html`:
```html
<div class="selector-group" id="desktop-length-toggle">
<label class="selector-label" id="length-toggle-label">
{{.UI.ViewControls.Length}}:
</label>
<label class="icon-toggle">
<input type="checkbox"
id="lengthToggle"
aria-labelledby="length-toggle-label"
aria-describedby="length-toggle-desc">
<span class="icon-toggle-slider">...</span>
<span id="length-toggle-desc" class="sr-only">
{{.UI.ViewControls.LengthDescription}}
</span>
</label>
</div>
```
Mobile toggles in `templates/partials/navigation/hamburger-menu.html`:
```html
<div class="menu-control-item" id="mobile-length-toggle">
<label class="menu-control-label" id="menu-length-toggle-label">
<iconify-icon icon="mdi:file-document-outline"></iconify-icon>
<span>{{.UI.ViewControls.Length}}</span>
</label>
<label class="icon-toggle">
<input type="checkbox"
id="lengthToggleMenu"
aria-labelledby="menu-length-toggle-label">
<span class="icon-toggle-slider">...</span>
</label>
</div>
```
### Contact Form
Located in `templates/partials/modals/contact-modal.html`:
```html
<div class="form-group">
<label for="contact-email" class="form-label">
{{.UI.ContactModal.Form.Email}}
<span class="required-indicator">*</span>
</label>
<input type="email"
id="contact-email"
name="email"
required
aria-required="true"
placeholder="{{.UI.ContactModal.Form.EmailPlaceholder}}">
</div>
```
### Labeling Strategies
| Strategy | When to Use |
|----------|-------------|
| `<label for="id">` | Standard form inputs |
| `aria-labelledby` | Complex widgets, toggles |
| `aria-describedby` | Additional context/descriptions |
| `aria-label` | When no visible label exists |
---
## Keyboard Navigation
### Supported Shortcuts
| Key | Action |
|-----|--------|
| `Tab` | Move focus to next element |
| `Shift+Tab` | Move focus to previous element |
| `Enter` / `Space` | Activate focused button/link |
| `Escape` | Close modals |
| `?` | Open shortcuts modal |
| `Ctrl/Cmd + K` | Open command palette |
| `Ctrl/Cmd + P` | Print friendly version |
| `Ctrl/Cmd + +/-/0` | Zoom controls |
### Focus Management
- All interactive elements are focusable
- Focus is trapped inside open modals
- Focus returns to trigger element when modal closes
- Skip links available for screen reader users
### Implementation
```html
<!-- Modal with keyboard support -->
<dialog id="shortcuts-modal" class="info-modal"
_="on click call closeOnBackdrop(me, event)">
<!-- Press Escape to close (native dialog behavior) -->
<button class="info-modal-close"
commandfor="shortcuts-modal"
command="close"
aria-label="{{.UI.ShortcutsModal.Close}}">
<iconify-icon icon="mdi:close"></iconify-icon>
</button>
</dialog>
```
---
## Screen Reader Support
### Live Regions
Announcements for dynamic content changes:
```html
<!-- Loading indicator -->
<span id="loading"
role="status"
aria-live="polite"
aria-label="Loading">
<span class="loader"></span>
</span>
<!-- PDF selection announcement -->
<div id="pdf-selection-announcement"
class="sr-only"
aria-live="polite"
aria-atomic="true"></div>
<!-- Contact form response -->
<div id="contact-response"
class="contact-response"
role="status"
aria-live="polite"></div>
```
### Screen Reader Only Text
```css
.sr-only {
position: absolute;
width: 1px;
height: 1px;
padding: 0;
margin: -1px;
overflow: hidden;
clip: rect(0, 0, 0, 0);
white-space: nowrap;
border: 0;
}
```
### ARIA Landmarks
```html
<!-- Navigation -->
<nav role="navigation" aria-label="CV sections">...</nav>
<div class="action-bar" role="navigation" aria-label="Language and export controls">...</div>
<!-- Zoom control -->
<div id="zoom-control" role="group" aria-label="{{.UI.Widgets.ZoomControl.GroupLabel}}">
<input type="range"
aria-label="{{.UI.Widgets.ZoomControl.SliderLabel}}"
aria-valuemin="25"
aria-valuemax="300"
aria-valuenow="100"
aria-valuetext="100%">
</div>
```
---
## CSS Compatibility
### Browser Prefixes
All CSS properties with limited browser support include vendor prefixes:
```css
/* User selection prevention */
.toggle-switch {
-webkit-user-select: none; /* Safari */
user-select: none;
}
/* Backdrop blur effect */
.zoom-control {
backdrop-filter: blur(10px);
-webkit-backdrop-filter: blur(10px); /* Safari */
}
```
### Files Updated
| File | Property Fixed |
|------|---------------|
| `_toggles.css` | `-webkit-user-select` |
| `_zoom-control.css` | `-webkit-user-select` |
| `_sidebar.css` | `-webkit-user-select` |
| `_cv-section.css` | `-webkit-user-select` |
| `_breakpoints.css` | `-webkit-user-select` |
| `_toasts.css` | `-webkit-backdrop-filter` (already present) |
| `_modals.css` | `-webkit-backdrop-filter` (already present) |
### Feature Detection
For backdrop-filter, use `@supports`:
```css
@supports (backdrop-filter: blur(20px)) or (-webkit-backdrop-filter: blur(20px)) {
.blur-bar {
backdrop-filter: blur(20px) saturate(180%);
-webkit-backdrop-filter: blur(20px) saturate(180%);
}
}
```
---
## HTTP Headers
### Security Headers
Implemented in `internal/middleware/security.go`:
```go
func SecurityHeaders(next http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
// Prevent MIME type sniffing
w.Header().Set("X-Content-Type-Options", "nosniff")
// Prevent clickjacking
w.Header().Set("X-Frame-Options", "SAMEORIGIN")
// XSS Protection
w.Header().Set("X-XSS-Protection", "1; mode=block")
// Referrer policy
w.Header().Set("Referrer-Policy", "strict-origin-when-cross-origin")
// Content Security Policy
w.Header().Set("Content-Security-Policy", "...")
// HSTS (production only)
if os.Getenv("GO_ENV") == "production" {
w.Header().Set("Strict-Transport-Security",
"max-age=31536000; includeSubDomains; preload")
}
next.ServeHTTP(w, r)
})
}
```
### Cache Control
**Static Files** (CSS, JS, images):
```go
// 1 hour dev, 1 day production
w.Header().Set("Cache-Control", "public, max-age=86400")
```
**Dynamic Routes** (HTML pages):
```go
// Production: 5 minutes with must-revalidate
w.Header().Set("Cache-Control", "public, max-age=300, must-revalidate")
// Development: no cache
w.Header().Set("Cache-Control", "no-cache, no-store, must-revalidate")
```
---
## Testing
### Running Accessibility Tests
```bash
# Run accessibility test suite
bun run tests/mjs/60-accessibility.test.mjs
# Or with the test runner
cd tests && bun run run-all.mjs
```
### Test Coverage
The `60-accessibility.test.mjs` file tests:
1. **HTTP Security Headers** - X-Content-Type-Options, X-Frame-Options, CSP
2. **Cache-Control Headers** - Presence and correct values
3. **Buttons with Discernible Text** - All buttons have aria-label or visible text
4. **Form Elements with Labels** - All inputs have associated labels
5. **Toggle Checkboxes** - aria-labelledby with valid linked elements
6. **ARIA Landmarks** - Navigation, main, dialog elements
7. **Keyboard Navigation** - Focusable interactive elements
8. **Modal Accessibility** - Close buttons, aria attributes
9. **Color Theme Support** - Theme switcher availability
10. **Screen Reader Announcements** - Live regions for dynamic content
### Manual Testing
1. **Keyboard-only navigation**: Tab through all interactive elements
2. **Screen reader testing**: Use VoiceOver (macOS) or NVDA (Windows)
3. **High contrast mode**: Test visibility in Windows High Contrast
4. **Zoom testing**: Test at 200% browser zoom
---
