2. Multiple transition declarations across rules
   • Could be consolidated into utility classes
3. @for loop (lines 622-628) generating many CSS rules
   • Check if all generated rules are actually used
   • Consider compile-time optimization

Remediation:

• Remove redundant flex properties
• Consolidate transition declarations
• Audit @for loop output and optimize if needed

Issue 5c: Mobile Responsiveness Levels

Current Breakpoints: 768px, 480px, 380px

Issue #7: Blog Post Scheduling Limitations

Severity: 🟢 LOW
Category: Accessibility & Structure
Impact: Edge Cases, Accessibility
Status: Not Started

Description

The blog post scheduling feature (implemented in blog.md, lines 87-141) relies on client-side JavaScript with potential issues:

Issues Identified

1. No Fallback for JavaScript Disabled
   • Requires JavaScript to filter scheduled posts
   • No graceful degradation
   • Shows all posts if JS disabled
2. Inefficient Time Checking
   • Uses setInterval checking every 60 seconds
   • Potential battery drain on mobile devices
   • Could use more efficient event-based approach
3. Silent Failure Risk
   • Complex client-side logic
   • Could fail silently without user knowledge
   • No error logging or notification

Current Implementation

// Runs every 60 seconds
setInterval(() => {
  // Filters posts based on current time
}, 60000);

Remediation**:

• Add fallback message for JS-disabled browsers: “JavaScript required for scheduled posts”
• Consider server-side scheduling if possible (Jekyll plugin or deployment script)
• Throttle interval checking to 120 seconds for battery efficiency
• Add error handling and logging
