Increased .cv-main bottom padding from 1rem to 8rem to ensure:
- Footer is fully visible and not hidden behind content
- Adequate clearance for zoom control (positioned at bottom: 100px)
- Proper breathing room between content and footer
Result: Footer now properly visible in normal view
The margin-top: -60px on .cv-footer was pulling the footer up too much,
hiding the GitHub link and other footer content.
Removed the negative margin - the reduced .cv-main bottom padding
(1rem instead of 3rem) already provides better spacing without hiding content.
Result:
- Footer content (GitHub, LinkedIn links) now visible
- Still has better spacing than before
- Zoom control at 100px bottom clears footer properly
Fixed two issues with zoom and footer:
1. Dynamic height adjustment based on zoom level:
- Store original height on first zoom (dataset.originalHeight)
- Calculate scaled height: originalHeight × scale factor
- Set container height dynamically to match visual content
- Example: 50% zoom → height = originalHeight × 0.5
- Prevents empty space below content at low zoom
- Prevents overflow at high zoom
2. Footer spacing and positioning:
- Reduced .cv-main bottom padding: 3rem → 1rem
- Added .cv-footer margin-top: -60px to pull footer up
- Increased .zoom-control bottom: 70px → 100px
- Zoom control now clears footer GitHub link
Result:
- Footer appears immediately after content at any zoom level
- No wasted empty space below content
- Zoom control doesn't overlap GitHub link
- Page height dynamically adapts to zoom level
The viewport-centered zoom approach was creating empty space above
the content when zooming to 50%, causing the CV to move down.
Solution: Simple top-anchored zoom
- Removed all complex scroll compensation logic
- Set transform-origin to "top center" (fixed position)
- Page now scales naturally from the top without movement
- No dynamic transform-origin calculations
- No scroll position adjustments
Result:
- Page stays anchored at top during zoom
- No empty space created above content
- Clean, predictable zoom behavior
- Works correctly at all zoom levels (50%-200%)
The page simply scales up/down from the top center point,
maintaining its position without any jumping or space issues.
Changed zoom behavior from "page-relative" to "viewport-relative":
Before:
- Zoomed from top of page causing perspective/depth effect
- Content appeared to move "through" the viewer
- Disorienting experience when scrolled down
After:
- Zooms from center of YOUR viewport (where you're looking)
- Content expands both above and below your position
- You stay at your original viewing point - no movement
- Like pinch-to-zoom: magnifies what you're currently viewing
Technical implementation:
1. Calculate viewport center relative to page (scrollTop + viewportHeight/2)
2. Convert to percentage of page height
3. Set transform-origin dynamically to that percentage
4. Apply scale transform from your viewing position
5. Adjust scroll to keep same content at viewport center
CSS changes:
- Default transform-origin: center center (was top center)
- Added transition for transform-origin: 0s (instant, no animation)
- Maintains smooth 0.08s linear transform transition
Result: Natural, stable zoom that feels like magnifying glass
Design improvements based on user feedback:
- Move current zoom value inside circular reset button
- Add colorful gradient (red→orange→blue→green) to slider on hover
- Make reset button perfectly circular (44px diameter)
- Dynamic value display updates in real-time inside button
- Maintains gray monochrome when not hovering
- Enhanced visual feedback with smooth color transitions
- Mobile responsive with smaller circular button (38px)
Technical changes:
- HTML: Moved #zoom-value-current span inside button
- CSS: border-radius 50%, min-width/min-height for perfect circle
- CSS: Gradient hover for both WebKit and Firefox sliders
- JavaScript: Already compatible (targets same element ID)
Visibility Improvements:
- Background: darker gray rgba(128, 128, 128, 0.7) instead of light transparent
- Base opacity: 0.7 (was 0.3) - much more visible by default
- Text: white/light gray instead of dark gray (better contrast on gray bg)
- Slider track: lighter gray rgba(200, 200, 200, 0.5) - more visible
- Slider thumb: bright white with light border - stands out clearly
- Reset button: lighter background with white text - easier to see
- Larger padding and sizing for better visibility
- Hover state: full opacity with darker background
Result: Control is clearly visible while maintaining elegant gray aesthetic
PROBLEM:
- Previous grid approach (50% 30%) didn't work correctly
- Language selector is INSIDE .site-title div, not a separate grid column
- Grid structure: .site-title | .view-controls-center | .action-buttons-right
SOLUTION @ 540px:
Grid Structure:
- Changed .action-bar-content to single column (1fr)
- Hide .view-controls-center and .action-buttons-right
- .site-title becomes the only visible element
Flexbox Inside .site-title:
- .site-title: display: flex, justify-content: space-between
- .site-title-left: flex: 1 1 55% (hamburger + title area)
* Contains hamburger button and CV JAMR title
* flex-grow allows expansion, flex-shrink allows contraction
- .language-selector: flex: 0 0 35% (language buttons)
* Fixed at ~35% width, doesn't grow or shrink
* justify-content: flex-end (align buttons to right)
Text Overflow Protection:
- .site-title-link: overflow: hidden
- .site-title-text: white-space: nowrap, text-overflow: ellipsis
- Prevents title from breaking layout
RESULT:
Mobile distribution:
✓ Hamburger + Title area: ~55% (flexible)
✓ Language selector (EN/ES): ~35% (fixed)
✓ Remaining ~10%: gaps and padding
✓ Visual result: approximately 50% / 30% with breathing room
BENEFITS:
- Proper space distribution matching internal HTML structure
- Language buttons have adequate touch targets
- Title can truncate gracefully if needed
- All controls still accessible via hamburger menu
PROBLEM:
- Mobile action bar using equal width distribution (1fr auto 1fr)
- Not optimal space utilization on small screens
- Action buttons and center controls taking unnecessary space
SOLUTION @ 540px breakpoint:
.action-bar-content:
- Changed grid: 1fr auto 1fr → 50% 30%
- Hamburger menu + title area: 50% width
- Language selector area: 30% width
- Reduced gap: 2rem → 0.5rem
- Reduced padding: auto → 0.5rem horizontal
Hidden elements on mobile:
- .view-controls-center: display: none (moved to hamburger menu)
- .action-buttons-right: display: none (PDF/Print in hamburger menu)
RESULT:
Mobile layout distribution:
✓ Hamburger + CV title: ~50% (more breathing room)
✓ Language selector (EN/ES): ~30% (adequate space)
✓ Remaining 20%: natural spacing/padding
✓ Center controls hidden (accessible via hamburger menu)
✓ Action buttons hidden (accessible via hamburger menu)
BENEFITS:
- Better space utilization on small screens
- Clearer visual hierarchy
- More touch-friendly target areas
- All functionality still accessible via hamburger menu

- Right sidebar title was right-aligned instead of centered
- Inconsistent title alignment between left and right sidebars
SOLUTION:
All Sidebars (Desktop):
- .sidebar-title: text-align: center (all section titles centered)
Left Sidebar Content:
- .cv-sidebar-left .sidebar-content: text-align: left
- .cv-sidebar-left .skill-item: text-align: left
Right Sidebar Content:
- .cv-sidebar-right .sidebar-content: text-align: right
- .cv-sidebar-right .skill-item: text-align: right
Mobile @ 768px:
- Both sidebars content: text-align: left !important (unchanged)
RESULT:
Desktop:
✓ Left sidebar: title centered, content left-aligned
✓ Right sidebar: title centered, content right-aligned
✓ Visual consistency with centered titles
✓ Content flows naturally from title position
Mobile:
✓ Both sidebars: content left-aligned for readability
✓ No changes to mobile behavior
VISUAL HIERARCHY:
- Titles centered = visual anchors
- Content aligned to sidebar position = natural reading flow
PROBLEM:
- Right sidebar content was left-aligned on desktop
- Created visual inconsistency with sidebar position
SOLUTION:
Desktop (default):
- Added .cv-sidebar-right .sidebar-content { text-align: right; }
- Added .cv-sidebar-right .skill-item { text-align: right; }
- Content now aligns to the right side matching sidebar position
Mobile @ 768px:

- .footer-value: 1.1rem → 0.85rem (smaller, supporting text)
- .footer-value b: 1.2rem → 0.95rem (adjusted for consistency)
RATIONALE:
- Labels (linkedin_, github_, email@, phone#) are visual anchors
- Values (URLs, email, phone) are supporting details
- Inverted hierarchy provides better visual structure on mobile
- Labels now stand out as section headers
- Values are readable but less visually dominant
RESULT:
- Clearer visual hierarchy in mobile footer
- Labels more prominent as category identifiers
- Values easier to scan without overwhelming the layout
PROBLEM:
- Email and phone were appearing on the same line in mobile footer
- User wants each property (linkedin, github, domestika, email, phone) on its own line
SOLUTION:
- Added `.footer-content li { display: block !important; }` for mobile @ 900px
- Added `margin-bottom: 1.5rem` for spacing between footer items
- Overrides desktop `display: inline-block` behavior
RESULT:
- Each footer property now displays on a separate line in mobile view
- Better vertical spacing and readability
- Cleaner mobile footer layout
PROBLEM:
- Left and right sidebars occupy too much space on mobile

Changes to make the menu animation clearly visible:
- Added opacity transition (0 → 1) with 0.3s ease
- Changed max-height to fixed 800px for consistent timing
- Used cubic-bezier(0.4, 0, 0.2, 1) easing for natural feel
- Increased transition duration to 0.5s
- Combined max-height and opacity creates smooth expand + fade effect
The menu now smoothly grows from top-to-bottom with a visible fade-in,
making the animation much more apparent when hovering the hamburger button.
The menu was appearing instantly without animation because the overflow
property was changing from 'hidden' to 'auto' on hover, which disrupted
the max-height transition.
Fix: Keep overflow-y: auto consistent at all times. This allows the
max-height animation to work smoothly from 0 to calc(100vh - 50px),
creating a smooth top-to-bottom expansion effect.
Main menu changes:
- Changed from translateX (left-to-right slide) to max-height animation
- Menu now grows from top to bottom with smooth transition
- Transition time: 0.4s ease-in-out for natural feel
Submenu changes:
- Removed display:none which prevented animation
- Now uses only max-height and opacity transitions
- Submenu smoothly expands downward with fade-in effect
- Transition time: 0.4s for height, 0.3s for opacity
Both animations now provide better visual feedback and follow the natural
top-to-bottom reading pattern.
