  1. Semantic HTML Looking at the HTML structure:

      <div class="body h-[100vh] flex bg-slate-300">
          <div class="card w-[280px] h-[420px] m-auto bg-white rounded-2xl p-3">
              <div class="">
                  <img class="rounded-lg" src="images/image-qr-code.png" alt="qr-code-image">
              </div>
              <div class="p-4 mx-auto">
                  <h1 class="font-bold text-slate-900 text-center">Improve your front-end skills by building projects</h1>
                  <p class="font-normal text-slate-500 text-[12px] text-center my-2">Scan the QR code to visit Frontend Mentor and take your coding skills to the next level</p>
              </div>
          </div>
      </div>
  

  he solution uses basic div elements without semantic HTML tags. It could be improved by using:

  • main for the main content wrapper
  • article or section for the card component
  • header for the title section
  • footer for the descriptive text

  2. Accessibility

  Several accessibility improvements could be made:

  • Missing alt text is descriptive but could be more specific for the QR code
  • No ARIA landmarks or roles are defined
  • Color contrast appears good (dark text on white background)
  • Missing language attributes for text content
  • No skip links (though not critical for this simple layout) Suggested improvements:

  <main class="h-[100vh] flex bg-slate-300">
    <article class="card w-[280px] h-[420px] m-auto bg-white rounded-2xl p-3" role="article">
      <div class="qr-container">
        <img class="rounded-lg" src="images/image-qr-code.png" 
             alt="QR code linking to Frontend Mentor website" />
      </div>
      <header class="p-4 mx-auto">
        <h1 class="font-bold text-slate-900 text-center">
          Improve your front-end skills by building projects
        </h1>
        <p class="font-normal text-slate-500 text-[12px] text-center my-2">
          Scan the QR code to visit Frontend Mentor and take your coding skills to the next level
        </p>
      </header>
    </article>
  </main>
  

  3. Responsive Design

  The layout uses:

  • Flexbox for centering
  • Fixed width (w-[280px]) and height (h-[420px]) for the card
  • Viewport height (h-[100vh]) for full-height layout While this works, it could be improved by:
  • Using responsive units (rem/em) instead of fixed pixels
  • Adding media queries for different screen sizes
  • Considering minimum margins for very small screens

  4. Code Structure The code is: ✅ Relatively clean and readable ✅ Uses Tailwind CSS classes logically ✅ Maintains consistent indentation Areas for improvement:

  • Separate components into reusable parts
  • Use more semantic class names
  • Consider extracting common styles into Tailwind components

  5. Design Fidelity

  The implementation appears to be aligned with requirement on:

  • Centered card layout
  • Rounded corners
  • Appropriate spacing
  • Typography hierarchy
  • Color scheme using slate colors
