HTML Semantics

HTML semantics refers to the use of meaningful HTML elements that describe their content clearly to both developers and browsers. Semantic elements improve code readability, accessibility, and SEO.

  </nav>
</header>

Usage: Typically contains introductory content or navigation links.

2. <nav>

Defines a navigation section containing links.

<nav>
  <a href="#home">Home</a>
  <a href="#services">Services</a>
  <a href="#contact">Contact</a>
</nav>

Usage: Encapsulates primary navigation links.

3. <main>

Specifies the main content of the document, excluding repeated elements like headers, footers, or sidebars.
