Semantic HTML and Accessibility Best Practices

🧠 Semantic HTML & Accessibility Best Practices

Semantic HTML uses elements that clearly describe their role, improving both SEO and accessibility.

🏷️ Common Semantic Tags

• <header>: Top of the page or section
• <nav>: Navigation menus
• <main>: Main content area
• <section>: Thematic grouping of content
• <article>: Independent, self-contained content
• <footer>: Bottom of the page or section

💡 Benefits

• 🔍 Easier for search engines to index content
• 🧑‍🦯 Enhances screen reader navigation
• 🔧 Improves code readability and maintenance

♿ Accessibility Best Practices

• 🖼️ Provide descriptive alt text for images
• 🎨 Ensure sufficient color contrast
• 🔖 Use ARIA labels when semantic tags don’t suffice

📄 Example: Semantic Structure

<header>
  <h1>Site Title</h1>
</header>
<article>
  <h2>Article Title</h2>
  <p>Content...</p>
</article>
<footer>
  <p>Contact info</p>
</footer>

✅ Combining semantic HTML with accessibility techniques leads to inclusive, well-structured, and user-friendly web pages.
