Implements component-level skeleton loaders that display during language
transitions, providing visual feedback while content swaps.
**Implementation:**
- Dual-state structure: each component has actual-content + skeleton-content
- CSS toggles visibility via opacity transitions (250ms)
- Global hyperscript listener on <body> for language button clicks
- Adds .loading class to parent containers that persist across OOB swaps
- Skeleton shapes mimic actual components (header, name, photo, intro)
**Key Technical Solutions:**
- Event delegation using event.target.matches('.selector-btn')
- Parent container targeting to survive HTMX OOB innerHTML swaps
- CSS descendant selector .loading .component-wrapper for triggering
- Shimmer animation with GPU acceleration (1.8s infinite)
**Files Modified:**
- static/css/skeleton.css: Complete skeleton system with shimmer animation
- templates/index.html: Global hyperscript for .loading class management
- templates/partials/sections/header.html: Dual-state component structure
- templates/partials/navigation/language-selector.html: Removed local hyperscript
**Tests:**
- test-skeleton-verify.mjs: Validates skeleton across 4 language switches
- All tests passing: ✅ Consistent activation on every language change
Implemented dual-state skeleton system as specified in prompt:
- Each component has actual-content + skeleton-content structure
- CSS toggles visibility via .loading class on component-wrapper
- Individual skeleton boxes (name, photo, intro, etc.) with shimmer animation
- Hyperscript triggers loading state during language switch
Changes:
- skeleton.css: Complete component-level skeleton CSS system with shimmer
- language-selector.html: Hyperscript to add/remove .loading class
- header.html: Dual-state structure with skeleton placeholders
Behavior:
- Click language button → .loading class added to components
- Actual content fades out (opacity → 0) in 250ms
- Skeleton boxes appear and shimmer
- After HTMX swap + 100ms delay → .loading class removed
- New content fades in (opacity → 1) in 250ms
Test Results:
✅ Component wrapper structure verified
✅ Dual-state toggle working correctly
✅ Skeleton elements present and animated
✅ Shimmer animation active (1.8s infinite loop)
✅ Accessibility: respects prefers-reduced-motion
✅ Print: skeletons hidden, content always visible
Next: Add skeleton structure to remaining components (experience, education, skills, projects)
Previously, the .htmx-swapping class was only applied to the language
selector button target, not to the actual CV content containers that
were being swapped via hx-swap-oob.
Solution:
- Added hyperscript event handlers to language selector buttons
- On htmx:beforeRequest → add .htmx-swapping to both content wrappers
- On htmx:afterSwap → remove .htmx-swapping from both wrappers
Effect:
- Skeleton shimmer (opacity 0.3 + animated ::before overlay) now
appears on CV content during language switch (~500ms duration)
- Smooth transition with shimmer effect inside content area
- No external overlay layer - effect is within existing DOM structure
Verified with Playwright test showing:
✅ .htmx-swapping class applied during swap
✅ Opacity changes to 0.3
✅ ::before pseudo-element with shimmer animation active
User can now zoom up to 300% for better readability.
Changes:
- Update zoom slider max from 175 to 300
- Update aria-valuemax to 300
- Update display label to show 300
- Update README to reflect new range (25%-300%)
Tested with curl - verified max="300" in HTML output
Zoom level persistence was broken because hyperscript was setting the
container's value instead of the slider's value on page load.
Changes:
- Fix zoom-control.html line 10: set #zoom-slider's value (not 'my value')
- Add comprehensive zoom persistence test (10-zoom-persistence.test.mjs)
- Update cv-functions.js documentation to clarify hyperscript interop
- Add zoom control feature to README
Test results: 5/5 tests pass
- Zoom saves to localStorage when changed ✅
- Zoom restores correctly on page reload ✅
- Reset to 100% works and persists ✅
Architecture note:
- Hyperscript 'call' within _="" attributes requires global JS scope
- JavaScript wrappers bridge window exposure to hyperscript evaluate()
- Pattern: window.fn() → _hyperscript.evaluate('hyperscriptFn()')
CRITICAL BUG FIX: Hover states now sync between action bar and hamburger menu
Changes:
1. Added mouseenter/mouseleave handlers to menu PDF button
- templates/partials/navigation/hamburger-menu.html:178-181
- Added .menu-pdf-btn class for targeting
- Added hyperscript hover sync events
2. Updated syncPdfHover() function
- static/js/cv-functions.js:71-82
- Now selects both .pdf-btn and .menu-pdf-btn
- Both buttons get .pdf-hover-sync class on hover
3. Updated syncPrintHover() function
- static/js/cv-functions.js:88-99
- Now selects both .print-btn and .menu-print-btn
- Both buttons get .print-hover-sync class on hover
4. Added CSS for menu PDF button hover sync
- static/css/main.css:2690-2700
- .menu-pdf-btn.pdf-hover-sync styling (white bg, red icon)
- Matches action bar PDF button hover state
5. Created comprehensive hover sync test
- tests/mjs/8-hover-sync.test.mjs
- Tests all 4 hover scenarios (bar→menu, menu→bar for both buttons)
- Validates event handlers and CSS class application
- Manual verification instructions included
Behavior now correct:
✅ Hovering action bar PDF button highlights menu PDF button
✅ Hovering action bar Print button highlights menu Print button
✅ Hovering menu PDF button highlights action bar PDF button
✅ Hovering menu Print button highlights action bar Print button
Fixes documented bug from PROJECT-MEMORY.md Section 3.
This commit includes two major improvements:
1. Hyperscript Code Organization:
- Extracted all hyperscript blocks >3 lines into reusable functions
- Created 6 new functions in functions._hs:
* toggleCVLength(isLong) - CV length toggle sync
* toggleIcons(showIcons) - Icons toggle sync
* toggleTheme(isClean) - Theme toggle sync
* syncPdfHover(show) - PDF button synchronized hover
* syncPrintHover(show) - Print button synchronized hover
* highlightZoomControl(show) - Zoom control highlight effect
- Reduced inline hyperscript from 11+ lines to 1-2 lines per element
- Updated 8 template files to use function calls:
* hamburger-menu.html
* view-controls.html
* action-buttons.html
* download-button.html
* print-friendly-button.html
* zoom-toggle-button.html
2. Mobile Button Layout (max-width: 900px):
- Repositioned three fixed buttons (PDF, Print, Info) horizontally at bottom center
- Print button perfectly centered in viewport
- Download button on left, Info button on right
- Hidden zoom and shortcuts buttons on mobile (available in hamburger menu)
- Removed conflicting old mobile styles that were hiding print button
- Smooth hover transitions maintained with proper transform calculations
Technical details:
- Used CSS transform with calc() for precise horizontal positioning
- Maintained hover effects with combined translateX/translateY transforms
- Ensured accessibility with proper ARIA labels and spacing
- All functions check element existence before manipulation
- LocalStorage sync maintained across desktop/mobile toggles
- Removed .zoom-active CSS class and JavaScript logic
- Zoom button stays same gray color whether zoom is on or off
- Fixed Show Zoom menu button visibility (changed inline style to zoom-hidden class)
- Menu item now correctly appears when zoom is hidden
Print Button Improvements:
- Hover shows white background with green icon (was green bg + white icon)
- Applied to all print buttons: fixed, action bar, and menu
- Default state remains dark gray with white icon
Zoom Control Improvements:
- Text now 100% white (was 70-95% opacity) for better readability
- Increased font sizes: labels 0.95rem (was 0.8rem), current value 1.05rem (was 0.9rem)
- Hover zoom toggle button highlights zoom control with blue glow shadow
- Active zoom button uses semi-transparent blue rgba(52, 152, 219, 0.5) instead of solid
Z-Index Fix:
- Hamburger menu now appears above fixed buttons (z-index: 1000 vs 999)
