HTML Semantics

Semantic elements clearly describe their meaning in a human- and machine-readable way.

What are Semantic Elements?

A semantic element clearly describes its meaning to both the browser and the developer.

Examples of non-semantic elements: <div> and <span> - Tells nothing about its content. Examples of semantic elements: <form>, <table>, and <article> - Clearly defines its content.

Semantic Elements in HTML5

Many web sites contain HTML code like: <div id="nav"> <div class="header"> <div id="footer"> to indicate navigation, header, and footer. HTML5 offers new semantic elements to define different parts of a web page:

• <article>
• <aside>
• <details>
• <figcaption>
• <figure>
• <footer>
• <header>
• <main>
• <mark>
• <nav>
• <section>
• <summary>
• <time>
