Day 10: HTML Best Practices & Mini Project

📘 Day 10: HTML Best Practices & Mini Project

This lesson collects HTML best practices you should adopt in real projects — accessibility, SEO basics, performance friendly markup, progressive enhancement and a mini project (portfolio/landing page) to practice everything.

1. Clean, semantic structure (use the right tags)

Prefer semantic elements (<header>, <main>, <article>, <section>, <footer>) over generic <div> when the element has meaning. Semantic markup helps screen readers and search engines.

2. Accessibility essentials

  • Always provide alt for meaningful images. If an image is decorative, use alt="".
  • Use <label for="id"> for form inputs and group related inputs with <fieldset>/<legend>.
  • Provide skip links (<a class="skip" href="#main">Skip to main content</a>) for keyboard users.
  • Use correct landmark roles: role="navigation", role="main", role="contentinfo" when necessary.
  • Ensure focus outlines are visible (do not remove :focus outlines without an accessible replacement).

3. SEO & metadata

Include descriptive <title>, unique meta description, and basic Open Graph tags for sharing:

<head>
  <meta charset="utf-8">
  <title>Jane Doe — Frontend Portfolio</title>
  <meta name="description" content="Portfolio of Jane Doe — frontend developer. Projects, contact, blog.">
  <meta property="og:title" content="Jane Doe — Portfolio">
</head>

4. Performance-friendly markup

  • Avoid heavy inline styles; use external CSS files for caching.
  • Optimize images (WebP/AVIF, multiple sizes) and set width/height to prevent layout shift.
  • Lazy-load below-the-fold images: <img loading="lazy">.
  • Minimize DOM depth and avoid unnecessary wrappers.

5. Progressive enhancement & graceful degradation

Start with a working HTML page (functional without JS) and enhance with JS/CSS — ensures users without JS still get content.

6. Headings & document outline

Use a logical heading order (one <h1> per page), then <h2>, <h3> etc. Don’t skip levels arbitrarily.

Mini Project — Build a Simple Portfolio / Landing Page

Requirements:

  • Use semantic structure: header, nav, main, section, article, footer.
  • Include a hero with heading, short intro, call-to-action (link or button).
  • Show a projects section with at least 2 project cards (image + caption).
  • Include a contact form (name, email, message) with labels.
  • Ensure images have alt text and the page has a proper title and meta description.
