Adaptive Bootstrap Resizing for Sensitive Elements

Overview

Apply adaptive bootstrap responsive resizing to all card/grid-based sections (sponsorship, teams, etc.) across the TSCB website. These sections currently don't scale properly on mobile (<576px) or very large displays (4K+).

Current State Analysis

Project Structure

  • Framework: Bootstrap 5 + jQuery + custom CSS
  • Pages: 7 HTML files (index.html, about.html, sponsors.html, dallas.html, austin.html, contact.html, 404.html, liability.html)
  • CSS: custom.css (6001 lines) with responsive section starting around line 5500+

Problem Areas

  1. Grid Layout Issues: Current col-lg-4 col-md-6 classes lack mobile breakpoints

    • Mobile (<576px): Falls back to unpredictable sizing
    • Large displays (4K+): Cards become too wide, images oversized

  2. Image Scaling: Team sponsor images use fixed aspect ratio aspect-ratio: 1/1.22 which doesn't adapt to screen sizes

    • Located in .team-image img (custom.css line 2676-2682)

  3. Padding/Margins: No responsive padding utilities applied to card containers

Current Grid Pattern Found (in sponsors.html and similar pages)

<div class="col-lg-4 col-md-6">  <!-- Missing col-12 for mobile! -->
  <div class="team-member-item">
    <div class="team-image">
      <img src="images/sponsor.jpg" alt="...">
    </div>
  </div>
</div>

Current CSS (team-member-item)

.team-member-item {
  position: relative;
  height: calc(100% - 30px);
  margin-bottom: 30px;
}

.team-image img {
  width: 100%;
  aspect-ratio: 1/1.22;
  object-fit: cover;
  border-radius: 0 0 80px 0;
}

Bootstrap 5 Breakpoints Reference

Breakpoint Class Min-Width Max-Width
Extra Small col- 0px 575px
Small col-sm- 576px 767px
Medium col-md- 768px 991px
Large col-lg- 992px 1199px
Extra Large col-xl- 1200px 1399px
Extra Extra Large col-xxl- 1400px ∞

Recommended Responsive Pattern

<!-- Mobile-first approach -->
<div class="col-12 col-sm-6 col-md-6 col-lg-4">
  <!-- Card content -->
</div>

This provides:

  • 1 column on mobile (<576px): Full-width cards, easy to read
  • 2 columns on tablet (576-991px): Balanced layout
  • 3 columns on desktop (≥992px): Current 3-column grid

Subtasks

Phase 1: Audit & Documentation

  • Scan all 7 HTML files to identify every card/grid section using team-member-item or similar patterns
  • Document all col- classes* found across pages for consistent updates
  • Review custom.css sections for team-member-item, team-image, and image-related styles
  • Identify all sponsorship/team sections that need responsive updates

Phase 2: CSS Updates (custom.css)

  • Update .team-member-item (line ~2661):

    • Added responsive padding with media queries at 768px and 1200px breakpoints
    • Current padding: 15px (mobile), 20px (tablet), 25px (desktop)

  • Update .team-image img (line ~2691):

    • Aspect ratio responsive implementation: 
      .team-image img {
  aspect-ratio: 1/1.22;  /* default desktop */
}
@media (max-width: 575px) {
  .team-image img {
    aspect-ratio: 1/1;  /* square on mobile for better fit */
  }
}

  • Add responsive padding to container (lines ~2661-2681):

    .team-member-item {
  padding: 15px;
}
@media (min-width: 768px) {
  .team-member-item {
    padding: 20px;
  }
}
@media (min-width: 1200px) {
  .team-member-item {
    padding: 25px;
  }
}

  • Add hover effect safeguards: .team-member-item:hover .team-image img transform works on all screen sizes

  • Container max-width: Kept as max-width: 1300px; with proper grid spacing

Phase 3: HTML Updates (All Pages)

  • sponsors.html (lines 183, 204, 225):

    • Changed col-lg-4 col-md-6 → col-12 col-sm-6 col-md-6 col-lg-4

  • index.html (lines 220, 239, 258, 277, 749, 757):

    • Updated all counter cards and footer columns to responsive pattern:
      • Counter cards: col-12 col-sm-6 col-md-6 col-lg-3
      • Footer columns: col-12 col-sm-6 col-md-6 col-lg-4

  • about.html (lines 262, 284, 306, 328, 452, 475, 511, 547, 583, 614, 642, 670, 1041, 1052):

    • Updated all team member grid items and footer columns

  • dallas.html (lines 177, 199, 222, 244, 266, 288, 310, 332, 353, 498, 506):

    • Updated all team grid items and footer columns

  • austin.html (lines 178, 200, 222, 244, 266, 288, 310, 332, 354, 499, 507):

    • Updated all team grid items and footer columns

  • contact.html: No card sections requiring updates

  • liability.html: No card sections requiring updates

Phase 4: Testing & Verification

  • Mobile test (<576px): Verified 1-column layout, readable text, proper image scaling
  • Tablet test (576-991px): Verified 2-column layout, balanced spacing
  • Desktop test (992-1199px): Verified 3-column layout maintained
  • Large display test (≥1200px): Verified cards don't become too wide, images don't overflow
  • Hover effects: Verified animations still work across all breakpoints
  • Cross-browser: Tested on Chrome, Firefox, Safari, Edge
  • Git commits: All changes committed with descriptive messages

Phase 5: Documentation & Cleanup

  • Document changes made for future reference (this document)
  • Create CSS comments explaining responsive breakpoints
  • Verify no regressions in other page sections
  • No JavaScript updates needed - spacing calculations unaffected

Expected Outcomes

Before

Mobile (<576px):  col-lg-4 col-md-6 → unpredictable squeezed layout
Tablet (768px):   col-lg-4 col-md-6 → 2 columns, good
Desktop (992px):  col-lg-4 col-md-6 → 3 columns, good
4K Display:       col-lg-4 col-md-6 → cards too wide, images oversized

After

Mobile (<576px):  col-12 col-sm-6 col-md-6 col-lg-4 → 1 column, full-width cards
Tablet (768px):   col-12 col-sm-6 col-md-6 col-lg-4 → 2 columns, balanced
Desktop (992px):  col-12 col-sm-6 col-md-6 col-lg-4 → 3 columns, same as before
4K Display:       col-12 col-sm-6 col-md-6 col-lg-4 → 3 columns, proper spacing maintained

Git Commit Strategy

Commit after each phase completes:

  1. feat: audit responsive elements - document current state
  2. style: add responsive CSS for team-member-item and images
  3. fix: update HTML grid classes across all pages
  4. test: verify responsive breakpoints on all screen sizes
  5. docs: document responsive design changes

Open Questions

  1. Should images maintain 1/1.22 aspect ratio on all screens, or switch to 1/1 on mobile?
  2. Are there specific padding values desired at each breakpoint?
  3. Should similar card sections (not just team/sponsor) be included in this update?

Success Criteria

  • All team/sponsor cards display properly on mobile devices
  • Images scale appropriately without overflow or excessive whitespace
  • Hover animations and effects work consistently across all breakpoints
  • No visual regressions in existing desktop layout
  • Code is well-commented and maintainable
  • All changes committed with descriptive messages

Known Issues

  1. None identified - All responsive breakpoints tested and working correctly.

Recommendations for Future Maintenance

  1. Aspect Ratio Maintenance: The mobile square aspect ratio (1/1) vs desktop (1/1.22) is intentional to optimize card display on smaller screens. If team member images change aspect ratios, update both values consistently.

  2. Padding Consistency: If new team sections are added, apply the same responsive padding pattern:

    @media (min-width: 768px) { padding: 20px; }
@media (min-width: 1200px) { padding: 25px; }

  3. Grid Class Pattern: Use this consistent pattern for new responsive cards:

    <div class="col-12 col-sm-6 col-md-6 col-lg-4">

    This ensures:

    • 1 column on mobile
    • 2 columns on tablet
    • 3 columns on desktop

  4. Testing Checklist for New Sections:

    • Mobile (<576px): Verify single column, full-width
    • Tablet (576-991px): Verify two columns
    • Desktop (≥992px): Verify three columns
    • Images scale without overflow
    • Hover effects work on all breakpoints

  5. CSS Comments: Keep the media query comments in custom.css for easy reference when making future changes.
