Semantic Elements
HTML semantic elements are tags that clearly describe their meaning in a human- and machine-readable way. They help structure the content of a webpage more logically and improve accessibility and SEO. Here’s an overview of some common semantic elements and examples of how they’re used:
-
<header>
Represents introductory content or a set of navigational links. It typically contains elements like logos, headings, or navigation menus.<header> <h1>My Website</h1> <nav> <ul> <li><a href="#home">Home</a></li> <li><a href="#about">About</a></li> <li><a href="#contact">Contact</a></li> </ul> </nav> </header>
-
<nav>
Defines a set of navigation links. It’s used to group navigation links into a cohesive section.<nav> <ul> <li><a href="#home">Home</a></li> <li><a href="#services">Services</a></li> <li><a href="#contact">Contact</a></li> </ul> </nav>
-
<article>
Represents a self-contained piece of content that could be distributed independently. It could be a blog post, news article, or any other standalone content.<article> <h2>My First Blog Post</h2> <p>Welcome to my first blog post. Here I will share some interesting thoughts...</p> </article>
-
<section>
Represents a thematic grouping of content, typically with a heading. It’s used to break content into different sections.<section> <h2>About Us</h2> <p>We are a company that specializes in...</p> </section>
-
<aside>
Represents content that is tangentially related to the content around it, such as sidebars or pull quotes.<aside> <h3>Did you know?</h3> <p>We offer a wide range of services...</p> </aside>
-
<footer>
Represents the footer of a section or page. It usually contains information like copyright notices, contact information, or related links.<footer> <p>© 2024 My Website</p> <a href="#privacy-policy">Privacy Policy</a> </footer>
-
<main>
Represents the dominant content of the<body>
. There should be only one<main>
element per document. It’s used to encapsulate the core content of the page.<main> <h1>Welcome to My Website</h1> <p>This is the main content of the webpage...</p> </main>
-
<figure>
and<figcaption>
Used for grouping media content (like images or videos) and their captions.<figure> <img src="image.jpg" alt="A beautiful landscape"> <figcaption>A beautiful landscape.</figcaption> </figure>
Using these semantic elements helps create a more readable and maintainable HTML structure, which benefits both users and search engines.
