Fixes info modal positioning to be perfectly centered on mobile devices
in all orientations.
ISSUE:
- Info modal was not centered on mobile viewports
- User reported "pop-up of information in mobile it is not centered"
- Modal positioning relied on inset:0 + margin:auto which doesn't
work consistently on mobile devices
FIX:
- Added explicit mobile centering using transform translate(-50%, -50%)
- Position: top: 50%, left: 50% with transform centering
- Applied to all modals: info, keyboard shortcuts, and PDF download
- Added mobile-specific fade-in animation preserving centering
- Constrained modal to viewport with calc(100vw - 2rem) width/height
Files modified:
- static/css/04-interactive/_modals.css - Mobile centering for all modals
- tests/mjs/58-modal-centering-test.mjs - Validation test
Test results:
✅ Portrait (375×667): Perfect center - 0px offset
✅ Landscape (667×375): Perfect center - 0px offset
✅ Modal center matches viewport center exactly
Fixes three critical mobile UI issues:
1. Theme Button Transparency (FIXED)
- Changed theme button from 50% to full opacity on mobile
- Updated _themes.css with rgba(x, y, z, 1) for all theme modes
- Added opacity: 1 !important to mobile media query
2. Info Button Color Differentiation (FIXED)
- Changed info button from green (#27ae60) to blue (#3498db)
- Now visually distinct from green back-to-top button
- Updated all states: default, hover, at-bottom
3. Button Layout Reorganization (FIXED)
- Added .is-mobile-device rules for 5-button layout (no shortcuts)
- Buttons centered without gap: Download, Print, Theme, Info, Back-to-top
- Total width: 290px (5 buttons + 4 gaps) vs 350px (6 buttons)
Files modified:
- static/css/01-foundation/_themes.css - Primary theme button fix
- static/css/04-interactive/_scroll-behavior.css - Info color + layout
- static/css/color-theme.css - Mobile device positioning sync
- tests/mjs/53-final-mobile-fixes-test.mjs - Comprehensive validation
Test results:
✅ Shortcuts hidden on real mobile (iPhone user agent)
✅ 5 buttons evenly spaced with no gap (60px spacing)
✅ Info button blue (52, 152, 219) vs back-to-top green (39, 174, 96)
✅ Theme button full opacity (alpha: 1, opacity: 1)
Issue 1: Blur bar compatibility (Android doesn't always show at bottom)
✅ Solution: Wrap blur bar in @supports query for backdrop-filter
- Only shows on devices that support backdrop-filter (primarily iOS)
- Android devices without support won't see the bar
- Prevents layout issues on non-iOS devices
Issue 2: Keyboard shortcuts button on real mobile (no physical keyboard)
✅ Solution: Device detection + conditional hiding
- Added device-detection.js: Detects real mobile vs desktop browser
- Checks user agent (Android, iPhone, iPad, etc.) + touch support
- Adds 'is-mobile-device' or 'is-desktop' class to <html>
- CSS hides shortcuts button only on real mobile devices
- Desktop browser in mobile view: shortcuts button still visible (for testing)
Implementation Details:
1. Device Detection (static/js/device-detection.js):
- User agent detection: /Android|iPhone|iPad|etc./
- Touch support check: ontouchstart + maxTouchPoints
- Class added to <html>: is-mobile-device or is-desktop
2. Blur Bar (@supports query):
- Detects backdrop-filter support before applying
- iOS: Shows blur bar with backdrop-filter
- Android (most): No blur bar (no backdrop-filter support)
- Prevents empty/broken bar on incompatible devices
3. CSS Hiding Rules:
- .is-mobile-device .shortcuts-btn { display: none !important; }
- Also hides zoom-toggle-btn and zoom-control on real mobile
- Desktop mobile view: shortcuts button remains visible
Files Modified:
- static/js/device-detection.js: NEW - Device detection logic
- templates/index.html: Load device-detection.js early
- static/css/05-responsive/_breakpoints.css: @supports wrapper for blur bar
- static/css/04-interactive/_scroll-behavior.css: Hide shortcuts on real mobile
- tests/mjs/52-mobile-device-detection-test.mjs: Comprehensive device detection test
Test Results:
✅ iPhone (real mobile): is-mobile-device class, shortcuts hidden
✅ Desktop browser (mobile view): is-desktop class, shortcuts visible
✅ Blur bar: Only shows on devices with backdrop-filter support
Fixed two critical mobile view issues:
1. Extended CV Sidebar Accordion:
- Updated sidebar.html to use native <details> element (was div with onclick)
- Styled accordion header to match CV title badges dark theme (#303030)

- Result: Sidebars now collapse/expand properly with native HTML functionality
2. PDF Download Modal Centering:
- Added JavaScript-based centering for mobile viewports (≤768px)
- Uses inline styles with !important flag to override browser defaults

Technical notes:
- Modal centering required setProperty() with 'important' flag
- Accordion matches cv-title-badges-header style exactly
- All tests passing: accordion toggle, modal centering
Files modified:
- templates/partials/cv/sidebar.html
- static/css/05-responsive/_breakpoints.css

- tests/mjs/46-visual-accordion-style-test.mjs
The theme switcher and info button tooltips were appearing on the RIGHT
in mobile view instead of on TOP (like macOS Dock style) because they
didn't have the .fixed-btn class and weren't included in the mobile
media query rules.
Changes:
- static/css/04-interactive/_tooltips.css: Add .color-theme-switcher and
.info-button selectors to mobile @media (max-width: 900px) rules

Testing:
- Added mobile tooltip position test
- Verified theme switcher and info tooltips now positioned on top on mobile
- Desktop behavior unchanged (tooltips still on right)
Mobile tooltip positioning now consistent across ALL buttons:
✅ All bottom dock buttons show tooltips on TOP (macOS Dock style)
- Remove tooltip-left class from zoom and shortcuts buttons (all left-side buttons show tooltips on RIGHT)
- Add mobile CSS rules for fixed-btn tooltips to appear on TOP (like macOS Dock)
- Update button template comments to reflect correct positioning

removing the redundant toast notification that appeared when the modal
was closed during download. Updated tests to reflect the new behavior.

**Issue 1: URL corruption in "See this CV in..." links**
- Bug: replaceYearPlaceholder used fmt.Sprintf on ALL URLs
- URLs like "/?lang=es" were corrupted to "/?lang=es%!(EXTRA string=2025)"
- Fix: Changed to strings.ReplaceAll("{{YEAR}}", year)
- Result: Only replaces actual {{YEAR}} placeholders, leaves other URLs intact
**Issue 2: Download filename not respected**
- Bug: Shortcut URLs (cv-jamr-2025-en.pdf) redirected with HTTP 301
- Browsers used original URL filename instead of Content-Disposition header
- Fix: Generate PDF directly in DefaultCVShortcut handler
- Result: Returns PDF with correct filename in Content-Disposition header
Files changed:
- internal/models/cv.go: Fixed replaceYearPlaceholder function
- internal/handlers/cv.go: Changed redirect to direct PDF generation
Both fixes verified:
- "See this CV in Spanish" link: href="/?lang=es" ✓
- Download link: filename=cv-jamr-2025-en.pdf ✓
UX Improvement:
- Added visual feedback during PDF generation process
- Users now see immediate response when clicking download button
- Clear communication about what's happening during the wait
New Features:
- Loading overlay with animated spinner
- Format-specific estimated generation times (Short: ~3s, Default: ~4s, Long: ~8s)
- Blur effect on modal background during loading
- Bilingual support (English/Spanish)
- Automatic modal close after download completes
CSS Updates (static/css/04-interactive/_modals.css):
- Added .pdf-loading-overlay with glassmorphism effect
- Spinning animation for loader (1s linear infinite)
- Fade-in animation (300ms)
- Accessibility: respects prefers-reduced-motion
- Background blur when loading active
HTML Updates (templates/partials/modals/pdf-modal.html):
- Loading overlay structure with spinner
- Dynamic loading messages based on selected format
- Enhanced downloadPDF() function with timing logic
Before: Click → silence → download appears
After: Click → overlay + spinner + estimate → download appears
Problem: Inline icons embedded in responsibilities, courses, and
projects had explicit width='60' height='60' attributes that made
them too large (60px instead of ~16px).
Solution:
- Added CSS with !important to override inline width/height attributes
- Targeted inline icons in:
* Course responsibilities and descriptions
* Project descriptions and technologies
* Experience responsibilities (within divs)
- Preserved large icons (80px) for main company/course/project logos
Changes:
- static/css/03-components/_courses.css: Override to 1.2em
- static/css/03-components/_projects.css: Override to 1.2em
- static/css/03-components/_cv-section.css: Override to 1.2em
Test Results:
✅ 7 course inline icons: 16px × 16px
✅ Main company icons: 80px × 80px (preserved)
