HTML Semantic Elements

Semantic HTML elements clearly describe their meaning in a human- and machine-readable way. These elements give structure and context to the content on a webpage, improving both accessibility and SEO.

Introduction to Semantic HTML

Semantic elements define the role or purpose of the content they contain. Instead of using generic tags like <div> or <span>, semantic tags such as <header>, <footer>, and <article> make the structure more meaningful.

<header>, <footer>, <nav>, <main>

<header> defines the top section of a page, usually containing a logo or navigation.

<footer> defines the bottom of the page, often with copyright or links.

<nav> represents a section for navigation links.

<main> holds the primary content of the document.

<header>
  <h1>My Website</h1>
  <nav>
    <a href="#">Home</a>
    <a href="#">About</a>
    <a href="#">Contact</a>
  </nav>
</header>

<main>
  <h2>Welcome to My Website</h2>
  <p>This is the main content area.</p>
</main>

<footer>
  <p>© 2025 My Website. All rights reserved.</p>
</footer>

<section>, <article>, <aside>, <figure>

<section> groups related content together. Think of it as a chapter of a book.

<article> represents an independent piece of content (e.g., a blog post or news article).

<aside> contains content that's related to the main content but can stand alone (like a sidebar).

<figure> is used to group media content (like images), often with a <figcaption>.
