Heading Tags

HTML has six levels of headings, from <h1> (the most important) down to <h6> (the least important). They work like the headings and sub-headings in a book.

Syntax:

<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>

By default, browsers show <h1> the biggest and boldest, and each level after it a little smaller.

Why headings matter

• Structure: they break your content into clear sections.
• SEO: Google uses headings to understand what your page is about.
• Accessibility: screen-reader users jump from heading to heading to scan a page.
