Syntax

<h1>…</h1> to <h6>…</h6>

Example

Try it

<h1>Web development</h1>
<h2>HTML</h2>
<h3>Semantic elements</h3>
<h2>CSS</h2>

One h1 per page is a safe default. Screen readers navigate by heading level.

Reference pages are the quick answer. The course explains the why, shows the full example and ends with a challenge.
