🔧 Accessibility & Compatibility Fixes - Version 2

Additional Issues Fixed

1. Accessibility: Remaining aria-expanded Issues

Problem

aria-expanded was used on ResizablePanel, but it's not a collapsible element in the traditional sense (it's a resizable panel, not an accordion).

Solution

Removed aria-expanded from ResizablePanel components. This attribute should only be used on elements that actually expand/collapse content (like accordions, menus, etc.).

Before:

<div aria-expanded="!isCollapsed">

After:

<div aria-label="panel">

2. Other: Form Fields Missing id/name Attributes

Problem

Form inputs were missing id and name attributes, which are required for:

• Accessibility (label association)
• Form submission
• Browser autocomplete
• Testing

Solution

Added id, name, and associated <label> elements to all form inputs:

Files Fixed:

1. AI Panel Input (AIPanel.vue):

   <label for="ai-input-field" class="sr-only">Ask AI assistant</label>
   <input
     id="ai-input-field"
     name="ai-message"
     aria-label="Ask AI assistant"
   />
   

2. Admin Panel Login (AdminPanel.vue and AdminPanel.tsx):

   <label for="admin-username" class="sr-only">Username</label>
   <input
     id="admin-username"
     name="username"
     aria-label="Username"
   />
   
   <label for="admin-password" class="sr-only">Password</label>
   <input
     id="admin-password"
     name="password"
     aria-label="Password"
   />
   

3. AI Send Button:

   <button
     title="Send message"
     aria-label="Send message to AI assistant"
     type="button"
   >
     <span class="sr-only">Send message</span>
     <i class="fas fa-paper-plane" aria-hidden="true"></i>
   </button>
   

3. Compatibility: text-size-adjust Browser Support

Note

The warning about text-size-adjust not being supported by Firefox and Safari is expected. This is a progressive enhancement:

• Chrome/Edge: Full support with text-size-adjust
• Firefox/Safari: Falls back gracefully (no impact)
• Best Practice: Include both -webkit-text-size-adjust and text-size-adjust for maximum compatibility

Current Implementation:

html {
  -webkit-text-size-adjust: 100%; /* Safari, Chrome (legacy) */
  text-size-adjust: 100%;          /* Chrome 54+, Edge 79+ */
}

This is correct and follows best practices. The warning is informational, not an error.

Server-Side Issues (Documented)

Performance & Security Headers

These issues require server-side configuration. See SERVER_HEADERS.md for complete implementation guide:

1. Cache-Control Headers

   • Static assets: Cache-Control: public, max-age=31536000, immutable
   • HTML: Cache-Control: no-cache, no-store, must-revalidate

2. Security Headers

   • X-Content-Type-Options: nosniff
   • Content-Security-Policy (adjust for production)
   • Remove Expires header (use Cache-Control instead)

3. Content-Type with Charset

   • All text responses: Content-Type: text/html; charset=utf-8

Remaining Non-Critical Warnings

1. div[popover] not supported by Firefox < 125

• Status: Not used in our code
• Impact: None
• Action: None needed

2. meta[name=theme-color] not supported by Firefox

• Status: Progressive enhancement
• Impact: Works in Chrome/Edge/Safari, ignored in Firefox
• Action: None needed (graceful degradation)

3. CSP eval warning

• Status: Development mode only (Vite HMR)
• Impact: None in production
• Action: Remove 'unsafe-eval' from CSP in production
