<header> Tag

<header> page ya section ka introduction hota hai. Isme logo, heading, navigation ya short intro text ho sakta hai.

<header> <h1>Learn HTML Step by Step</h1> <p>Beginner to Advanced HTML Course</p> </header>

Tip:
Har page me sirf ek main <header> hona chahiye jo primary content ko introduce kare.

<nav> Tag

<nav> tag navigation links ke liye hota hai. Isme menus, category links ya pagination ho sakti hai.

<nav> <a href="#">Home</a> | <a href="#">HTML</a> | <a href="#">CSS</a> | <a href="#">Contact</a> </nav>

SEO Tip:

ke andar sirf important navigation links hi rakhein, unnecessary links se avoid karein.

<main> Tag

<main> tag page ka primary content hold karta hai. Screen readers isi area ko most important samajhte hain.

• Page ka central content
• Header, nav, footer ke bahar hota hai
• Sirf ek <main> per page

<section> Tag

<section> logically related content group karta hai. Har section ka apna heading hona best practice hai.

<section> <h2>Why Learn HTML?</h2> <p>HTML web development ka foundation hai.</p> </section>

<article> Tag

<article> ek self-contained content block hota hai. Blog posts, news articles aur comments ke liye ideal hai.

<article> <h2>HTML Basics</h2> <p>HTML se web page ka structure banta hai.</p> </article>

Difference:
Article independent hota hai, jabki section dependent hota hai page context par.

<aside> Tag

<aside> main content se related but secondary content ke liye hota hai jaise ads, author bio, related posts.

<aside> <h3>Related Topics</h3> <ul> <li>HTML Tags</li> <li>CSS Basics</li> </ul> </aside>

<footer> Tag

<footer> page ya section ka closing content hota hai. Isme copyright, author info, links hote hain.

<footer> <p>© 2025 Learn HTML. All rights reserved.</p> </footer>
