This PR completes the migration from Bootstrap 4 to Bootstrap 5.3.5
following the plan outlined in
[docs/Bootstrap5Migration.md](https://github.com/compiler-explorer/compiler-explorer/blob/mg/bootstrap5/docs/Bootstrap5Migration.md).
## Migration Process
We followed a phased approach as documented in the migration plan:
1. **Phase 1: Dependency Updates and Basic Setup**
- Updated Bootstrap from 4.6.2 to 5.3.5
- Added @popperjs/core dependency (replacing Popper.js)
- Updated Tom Select theme from bootstrap4 to bootstrap5
2. **Phase 2: Global CSS Class Migration**
- Updated directional utility classes (ml/mr → ms/me)
- Updated floating utility classes (float-left/right → float-start/end)
- Updated text alignment classes (text-left/right → text-start/end)
3. **Phase 3: HTML Attribute Updates**
- Updated data attributes to use Bootstrap 5 prefixes (data-bs-toggle,
data-bs-target, etc.)
- Fixed tab navigation issues
4. **Phase 4: JavaScript API Compatibility Layer**
- Created bootstrap-utils.ts compatibility layer
- Updated component initialization for modals, dropdowns, popovers, etc.
5. **Phase 5: Component Migration**
- Updated and tested specific components (modals, dropdowns, toasts,
etc.)
- Fixed styling issues in cards and button groups
6. **Phase 6: Form System Updates**
- Updated form control classes to Bootstrap 5 standards
- Updated checkbox/radio markup patterns
- Simplified input groups
7. **Phase 7: Navbar Structure Updates**
- Updated navbar structure with container-fluid
- Fixed responsive behavior
8. **Phase 8: SCSS Variables and Theming**
- Added custom CSS fixes for navbar alignment
- Verified theme compatibility
9. **Phase 9: Accessibility Improvements**
- Updated sr-only to visually-hidden
- Added proper ARIA attributes
- Enhanced screen reader support
## Key Changes
- No more jQuery dependency in Bootstrap 5
- New prefix for data attributes (data-bs-*)
- Improved accessibility with ARIA attributes
- Updated positioning classes (start/end instead of left/right)
- Simplified input group structure
## Test Plan
1. **Navigation Testing**
- Verify all dropdown menus open and close properly
- Test mobile menu responsiveness
- Check tab navigation in settings dialog
2. **Component Testing**
- Verify all modals open and close correctly (settings, share,
load/save)
- Test tooltips and popovers
- Check form controls in different dialogs
3. **Layout Testing**
- Test responsiveness on different screen sizes
- Verify proper alignment of elements
- Check dark mode compatibility
4. **Specific Features to Test**
- Compiler selection and options
- Share dialog functionality
- Settings dialog
- Tree view (IDE mode)
- Font selection dropdown
5. **Browser Testing**
- Test in Chrome, Firefox, Safari
- Test in mobile browsers
## Note on Further Improvements
After this migration is stable, we could consider Phase 12: removing
jQuery dependency entirely, as Bootstrap 5 no longer requires it. This
would be a separate effort.

The `input` field for compiler arguments in noscript has `autocomplete`
set to off, which results in the field being cleared between each
compilation on Safari & Samsung Internet.
Also, autocorrect and auto capitalization are enabled in the source code
`textarea`, which makes it incredibly tedious to type anything on
mobile. This PR addresses both of these issues.
