Responsive Design¶
Breakpoint Strategy¶
The navigation uses a three-tier responsive strategy:
1. Mobile View (< 992px)¶
- Offcanvas menu: Slides in from right side
- Touch-optimized: 48-52px touch targets (exceeds WCAG 44px minimum)
- Vertical layout: Full-width menu items
- Enhanced close button: 48px with rotation animation
- Smooth animations: Cubic-bezier easing for natural feel
@media (max-width: 991.98px) {
#bdNavbar .nav-link {
padding: 0.875rem 1rem;
min-height: 52px;
border-radius: 0.375rem;
}
}
2. Compact Desktop (992px - 1199px)¶
- Icon-only navigation: Saves horizontal space
- Enhanced tooltips: 400ms delay, proper placement
- 44px minimum targets: Meets WCAG requirements
- Larger icons: 1.15rem for better visibility
- Hover feedback: Transform animations and shadows
@media (min-width: 992px) and (max-width: 1199.98px) {
#bdNavbar .nav-link {
padding: 0.625rem 0.75rem;
min-width: 44px;
min-height: 44px;
}
}
3. Full Desktop (≥ 1200px)¶
- Full labels with icons: Complete navigation text
- Hover interactions: Scale animations on icons
- Wider dropdowns: 14rem (increased from 12rem)
- Enhanced spacing: Better visual hierarchy
Site Title Responsiveness¶
Progressive text truncation based on viewport:
| Breakpoint | Max Width | Use Case |
|---|---|---|
| ≥ 768px | 100% | Full title visible |
| 576px - 767px | 60vw | Medium truncation |
| 375px - 575px | 50vw | Significant truncation |
| < 375px | 40vw | Aggressive truncation + smaller logo |
Accessibility Improvements¶
WCAG 2.1 AA Compliance¶
Touch Target Sizes¶
- Mobile: 48-52px (exceeds 44px minimum)
- Desktop: 44px minimum
- Utility buttons: 48px on mobile, 44px on desktop
ARIA Labels & Roles¶
<!-- Header with proper role -->
<header role="banner">
<nav aria-label="Primary navigation">
<ul role="menubar">
<li role="none">
<a role="menuitem" aria-current="page">Home</a>
</li>
</ul>
</nav>
</header>
Focus Management¶
- Clear focus indicators: 2px outline + 4px box-shadow
- Focus trap: Keeps focus within offcanvas menu
- Skip to content: Screen reader accessible
- Visible focus: High contrast outlines
.nav-link:focus-visible {
outline: 2px solid var(--bs-primary);
outline-offset: 2px;
box-shadow: 0 0 0 4px rgba(13, 110, 253, 0.1);
}
Keyboard Navigation¶
Enhanced Key Support¶
- Arrow keys: Navigate through menu items
- Home/End: Jump to first/last item
- Enter/Space: Open dropdowns
- Escape: Close dropdown and return focus
- Tab: Close dropdown and continue
Implementation¶
dropdown.addEventListener('keydown', (e) => {
if (e.key === 'Home') {
e.preventDefault();
items[0]?.focus();
} else if (e.key === 'End') {
e.preventDefault();
items[items.length - 1]?.focus();
}
});
Visual Design Enhancements¶
Modern UI Components¶
Dropdown Menus¶
- Rounded corners: 0.5rem border-radius
- Enhanced shadows:
0 0.5rem 1.5rem rgba(0, 0, 0, 0.175) - Smooth animations: Transform-based reveal
- Proper spacing: 0.5rem padding, 0.125rem gaps
.dropdown-menu {
border-radius: 0.5rem;
box-shadow: 0 0.5rem 1.5rem rgba(0, 0, 0, 0.175);
transform: translateY(-0.5rem);
transition: all 0.2s cubic-bezier(0.4, 0, 0.2, 1);
}
Hover States¶
- Subtle lift:
translateY(-1px) - Background change:
var(--bs-tertiary-bg) - Icon scaling:
scale(1.1) - Smooth transitions: 0.2s ease-in-out
Active States¶
- Underline indicator: 2px bar below active nav item
- Primary color: Clear visual distinction
- Font weight: 600 for emphasis
- Dropdown items: Full background highlight
.nav-link[aria-current="page"]::after {
content: '';
position: absolute;
bottom: 0;
width: 60%;
height: 2px;
background-color: var(--bs-primary);
}
Dark Mode Support¶
Enhanced shadows for dark mode:
@media (prefers-color-scheme: dark) {
.dropdown-menu {
box-shadow: 0 0.5rem 1.5rem rgba(0, 0, 0, 0.4);
}
}
Touch Target Optimization¶
Mobile Touch Targets¶
All interactive elements meet or exceed WCAG guidelines:
| Element | Size | Standard |
|---|---|---|
| Nav links | 52px | ✅ Exceeds 44px |
| Dropdown toggle | 48px | ✅ Exceeds 44px |
| Close button | 48px | ✅ Exceeds 44px |
| Utility buttons | 48px | ✅ Exceeds 44px |
| Dropdown items | 48px | ✅ Exceeds 44px |
Desktop Click Targets¶
| Element | Size | Standard |
|---|---|---|
| Nav links | 44px | ✅ Meets 44px |
| Dropdown toggle | 44px | ✅ Meets 44px |
| Utility buttons | 44px | ✅ Meets 44px |
Animation & Transitions¶
Timing Functions¶
- Primary:
cubic-bezier(0.4, 0, 0.2, 1)- Natural motion - Duration: 0.2s for micro-interactions, 0.3s for major transitions
- Hover delay: 150ms to prevent accidental triggers
- Tooltip delay: 400ms show, 100ms hide
Transform Animations¶
Hover Effects¶
Dropdown Reveal¶
.dropdown-menu {
transform: translateY(-0.5rem);
opacity: 0;
&.show {
transform: translateY(0);
opacity: 1;
}
}
Icon Rotation¶
.dropdown-toggle::after {
transition: transform 0.2s ease-in-out;
}
.dropdown-toggle.show::after {
transform: rotate(180deg);
}
Mobile Animations¶
.dropdown-menu {
max-height: 0;
transition: max-height 0.35s cubic-bezier(0.4, 0, 0.2, 1);
&.show {
max-height: 600px;
}
}
Auto-Hide Navigation¶
Configuration¶
const SCROLL_THRESHOLD = 80; // Hide after 80px scroll
const SCROLL_DELTA = 3; // Minimum scroll for detection
const SHOW_ON_TOP_OFFSET = 50; // Show when within 50px of top
Behavior¶
- Hide on scroll down: Past 80px threshold
- Show on scroll up: Immediate response
- Always visible: When within 50px of top
- Smooth transition: 0.3s cubic-bezier
- Respects motion preferences: Disabled for
prefers-reduced-motion
Keyboard Navigation¶
Complete Key Bindings¶
| Key | Action | Context |
|---|---|---|
| Tab | Navigate forward | All |
| Shift+Tab | Navigate backward | All |
| Enter | Activate link/button | All |
| Space | Activate button | Buttons |
| Escape | Close dropdown | Dropdowns |
| ArrowDown | Next menu item | Dropdowns |
| ArrowUp | Previous menu item | Dropdowns |
| Home | First menu item | Dropdowns |
| End | Last menu item | Dropdowns |
Focus Management¶
// Focus trap for offcanvas
offcanvasEl.addEventListener('shown.bs.offcanvas', () => {
const firstFocusable = offcanvasEl.querySelector(
'button, [href], input, select, textarea, [tabindex]:not([tabindex="-1"])'
);
firstFocusable?.focus();
});
