HTML Semantic Elements

🌐 HTML Semantic Elements

HTML Semantic Elements are tags that clearly describe their meaning—both to the browser and to developers.

They make your code readable, accessible, SEO-friendly, and future-proof.

 1. What Are Semantic Elements?

Semantic elements tell what the content is, not just how it looks.

❌ Non-semantic

<div id="header"></div>
<div id="nav"></div>
<div id="content"></div>
<div id="footer"></div>

✅ Semantic

<header></header>
<nav></nav>
<main></main>
<footer></footer>

👉 Same layout, better meaning.

 2. Why Use Semantic HTML?

✔ Better SEO (search engines understand structure)
✔ Better Accessibility (screen readers)
✔ Cleaner & maintainable code
✔ Industry best practice
