🟡 Improvement Suggestions

Performance

  1. Preconnect to external domains:

    <link rel="preconnect" href="https://github.com">
<link rel="preconnect" href="https://hub.docker.com">

  2. Lazy loading for images (if added):

    <img loading="lazy" ...>

  3. Resource hints:

    <link rel="dns-prefetch" href="https://github.com">

SEO

  1. Breadcrumbs schema for documentation
  2. FAQ schema for common questions
  3. Sitemap.xml (generate)
  4. robots.txt (add)

Accessibility

  1. Focus visible styles - add clear outline for keyboard navigation
  2. Contrast ratio - verify all colors meet WCAG AA (4.5:1)
  3. ARIA landmarks - add role="navigation", role="main", role="contentinfo"

Content

  1. Missing og:image - create social media image (1200x630px)
  2. Missing favicon.ico - add for older browsers
  3. Manifest.json - for PWA support

🔧 Fixed Issues

1. ✅ Added Structured Data (Schema.org)

{
  "@context": "https://schema.org",
  "@type": "SoftwareApplication",
  "name": "MDDB",
  ...
}

2. ✅ Added <main> wrapper

All content wrapped in <main id="main-content"> for better semantics and accessibility.

3. ✅ Added Skip Link

<a href="#main-content" class="skip-to-main">Skip to main content</a>

4. ✅ Improved mobile menu accessibility

  • Added aria-expanded
  • Added .sr-only text
  • Added aria-hidden on decorative spans

5. ✅ Added defer to JavaScript

Scripts don't block rendering.

6. ✅ Added accessibility styles

  • .skip-to-main - skip link
  • .sr-only - screen reader only content
