Switched from Flexbox to CSS Grid to enable true staggered animations.
Why Grid works better:
- Grid children maintain their grid cell during layout changes
- Buttons can transition individually within their cells
- grid-auto-flow change doesn't force simultaneous repositioning
Changes:
- Container: display: grid with grid-auto-flow
- Desktop: grid-auto-flow: row (vertical stack)
- Mobile: grid-auto-flow: column (horizontal row)
- Buttons: transition: all 0.5s with staggered delays (0s, 0.08s, 0.16s, 0.24s, 0.32s)
Result: Each button now cascades independently when resizing between
desktop and mobile layouts, creating the smooth wave effect.
The issue was that 'transition: all' on the container was forcing all
buttons to move together. Fixed by:
1. Container now transitions only: left, bottom, gap, transform
(NOT flex-direction or all properties)
2. Buttons transition only: transform, opacity, background-color, box-shadow, color
(NOT all properties)
3. Increased stagger delays for better visual effect:
- Button 1: 0s (instant)
- Button 2: 0.08s
- Button 3: 0.16s
- Button 4: 0.24s
- Button 5: 0.32s
4. Added flex-direction: 0s transition in mobile to instant switch direction
while buttons still cascade to new positions
Result: Each button now animates independently with cascading wave effect
when switching between desktop (vertical) and mobile (horizontal) layouts.
Implemented beautiful cascading animation effect where each button
animates individually with a staggered delay.
Changes:
- Each button now has transition: all 0.4s cubic-bezier(0.4, 0, 0.2, 1)
- Added nth-child selectors with progressive delays:
* Button 1: 0.05s delay
* Button 2: 0.10s delay
* Button 3: 0.15s delay
* Button 4: 0.20s delay
* Button 5: 0.25s delay
Effect:
When viewport changes (desktop ↔ mobile), buttons don't move as a group.
Instead, they cascade one by one creating a wave-like animation:
- Desktop→Mobile: Buttons flow from vertical to horizontal sequentially
- Mobile→Desktop: Buttons stack from horizontal to vertical one by one
This creates a much cooler, more polished animation than moving all
buttons simultaneously. The 50ms stagger creates perfect visual rhythm.
Fixes:
1. ✅ Reversed button order - Info at bottom, Download at top
- Desktop (bottom→top): Info → Shortcuts → Zoom → Print → Download
- Mobile (left→right): Download → Print → Shortcuts → Info
2. ✅ Restored smooth morphing transitions
- Added transition: all 0.4s cubic-bezier(0.4, 0, 0.2, 1)
- Container smoothly transforms from vertical to horizontal
- Buttons smoothly reposition during responsive transition
3. ✅ Preserved all special hover behaviors
- Zoom button: Blue hover + highlights zoom control
- Print button: White bg + green icon on hover (synchronized)
- Download button: Red bg on hover (synchronized)
- All sync functions working: syncPdfHover, syncPrintHover, highlightZoomControl
The flexbox container now has the correct button order AND smooth animations!
Major architectural improvement for button management:
Desktop Layout (left side, vertical):
- Created .fixed-buttons-container positioned left: 2rem, bottom: 2rem
- Buttons stack vertically with flex-direction: column
- Order (bottom to top): Info → Shortcuts → Zoom → Print → Download
- 1rem (16px) gap between buttons
- All buttons 50×50px with consistent styling
- Easy to add/remove buttons - just add template to container
Mobile Layout (bottom center, horizontal):
- Container switches to flex-direction: row at @media (max-width: 900px)
- Centered with left: 50% and transform: translateX(-50%)
- 10px gap between buttons
- Zoom button hidden on mobile (display: none)
- 4 visible buttons: Info, Shortcuts, Print, Download
Benefits:
✅ Single source of truth - container manages all buttons
✅ Easy to add/remove buttons - no manual position calculations
✅ Responsive - automatic reflow from vertical to horizontal
✅ Maintainable - changes in one place affect all buttons
✅ Consistent spacing - gap property ensures even distribution
✅ Future-proof - adding button = adding template to container
Technical Implementation:
- Container uses position: fixed with flexbox
- Buttons use position: relative inside container (not fixed individually)
- All positioning managed by flexbox (gap, flex-direction, align-items)
- Hover states preserved with color-coded backgrounds per button
- Back-to-top button remains separate (not in container)
This replaces individual fixed positioning with a scalable flex layout.
Changes:
- Replaced fixed positioning with flexible layout for mobile buttons
- Now shows 4 buttons on mobile: Download, Print, Shortcuts, Info
- Hide only Zoom button on mobile (accessible via hamburger menu)
- All buttons now 50×50px (consistent size, info button was smaller)
- Even 10px spacing between buttons
- Perfectly centered as a group in viewport
- Future-proof: easy to add/remove buttons without breaking layout
Layout details:
- Total width: 4 buttons × 50px + 3 gaps × 10px = 230px
- Centered using calc(50% - offset) for each button
- Maintains smooth hover effects with translateY only
- All buttons at same vertical position (bottom: 1.5rem)
Benefits:
- Consistent button sizes across mobile/desktop
- Maintainable: adding/removing buttons only requires adjusting calculations
- Better UX: users can access all main actions from bottom bar
- Shortcuts and info buttons now easily accessible on mobile
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

* 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
- Added 0.3s ease transitions for background-color and color
- Icons now smoothly transition color as well

- 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)
- PDF buttons (fixed, action bar, menu) now sync hover states across all instances
- Print-friendly buttons (fixed, action bar, menu) sync green hover states
- White PDF icon with red hover background (#cd6060)
- Green print button hover (#27ae60)
- Implemented using hyperscript with .pdf-hover-sync and .print-hover-sync classes
- Creates cool visual feedback showing all related buttons simultaneously
- Moved menu hover logic from JavaScript to CSS selectors, reducing JS to minimal bridge code
- Replaced JavaScript-based toast timing with pure CSS animation lifecycle (slide in → stay → fade out)
- Removed unnecessary event handlers and legacy compatibility code for cleaner implementation
- Replace CSS zoom with transform: scale() for proper viewport extension
- Add dynamic margin-bottom to position footer correctly
- Remove zoom: 1 reset from fixed buttons (no longer needed)
- Enables true zoom from 10% to 500% that extends beyond viewport
- Add green background (#27ae60) to info and back-to-top buttons when at page bottom
- Implement bottom detection (within 50px threshold) in scroll handler
- Add conditional green hover to zoom reset button (only when zoom ≠ 100%)
- Enhance UX with visual feedback for scroll position and zoom state
Switched from transform: scale() to CSS zoom property on zoom-wrapper.
CSS zoom changes actual layout space, not just visual rendering:
- At 50% zoom, wrapper takes 50% space (no reserved empty space)
- Footer naturally follows right after zoomed content
- At 200% zoom, content extends beyond viewport with scrolling
- Fixes the large gray gap between content and footer
- Created zoom-wrapper div around cv-container
- Zoom now applies to wrapper only, footer adjusts naturally below
- Footer no longer scaled, stays at normal size
- Fixes gap between content and footer at low zoom levels
- Reduced back-to-top button size (35px default, grows to 50px on hover)
- Cleaner separation of concerns for zoom functionality
- Moved "Zoom" button from action bar to hamburger menu under "Acciones Rápidas"
- Close button (X) now grey/subtle by default (opacity: 0.7)
- Close button turns red only on hover for clear indication
- Updated JavaScript to reference show-zoom-menu-btn instead of show-zoom-btn
- Added preventDefault to showZoomControl to prevent link navigation
- Add close button (X) to zoom control widget
- Make zoom control draggable anywhere on screen
- Persist dragged position in localStorage (cv-zoom-position)
- Add "Zoom" button to action bar to show control when hidden
- Persist visibility state in localStorage (cv-zoom-visible)
- Cursor changes to "move" to indicate draggability
- Interactive elements (slider, buttons) don't trigger drag
- Position stays within viewport bounds
- All features work on desktop only (zoom hidden on mobile)
- Hide zoom control on mobile viewports (≤768px) via CSS
- Skip loading saved zoom on mobile, always use 100%
- Add resize handler to reset zoom when switching to mobile view
- Clean up unnecessary mobile-specific zoom styles
- Prevents confusion on touch devices where zoom is less useful
Changed zoom target from .cv-paper to .cv-container and .cv-footer to fix issue
where 50% zoom still reserved 100% document space creating empty areas. Both
elements now scale together, properly reducing space at low zoom levels while
keeping main action bar unaffected.
- Modified applyZoom() to target .cv-container and .cv-footer
- Added transform-origin, transition, and will-change to both CSS selectors
- Maintains proportional scroll compensation for smooth visual experience
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
- Replace blue border with green curly brackets { } using CSS pseudo-elements
- Add proper spacing and vertical centering with inline-flex
- Add engaging subtext below GitHub button: "Want to know how it's built?"
- Bilingual support for subtext (EN/ES)
- Change sidebar titles from center to left alignment for better readability
- Update badge from "Senior Consultant" to "Technical Consultant"
- Applies to both English and Spanish versions
- Changed right sidebar title alignment from center to right for consistency
- Added center alignment to sidebar accordion headers
- Fixed mobile sidebar alignments to respect left/right positioning (left sidebar: left-aligned, right sidebar: right-aligned)
PROBLEM:
- 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
