🤔 What are Semantic Tags?
Semantic HTML tags clearly describe the meaning of the content inside them — both to the browser and developers.
👉 “Semantic” means meaningful.
Example:
<header>Website Header</header>
🧠 This clearly tells that the content is a header, not just a random container.
❌ Non-Semantic vs ✅ Semantic
Non-Semantic tags (no meaning):
<div>Header</div>
Semantic tags (clear meaning):
<header>Header</header>
✅ Semantic tags explain what the content is, not just how it looks.
🏷️ Common Semantic HTML Tags
| <header> | Top section of a page |
| <nav> | Navigation links |
| <main> | Main content |
| <section> | Section of content |
| <article> | Independent content |
| <aside> | Sidebar content |
| <footer> | Bottom section |
🏗️ Simple Example
<body>
<header>
<h1>My Blog</h1>
</header>
<nav>
<a href="#">Home</a>
<a href="#">About</a>
</nav>
<main>
<article>
<h2>Blog Post</h2>
<p>This is my article.</p>
</article>
</main>
<footer>
