HTML Headings


HTML headings are titles or subtitles that you want to display on a webpage.


Example

Heading 1

Heading 2

Heading 3

Heading 4

Heading 5
Heading 6

HTML Headings

HTML headings are defined with the <h1> to <h6> tags.

<h1> defines the most important heading. <h6> defines the least important heading.

Example

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

Note: Browsers automatically add some white space (a margin) before and after a heading.


Headings Are Important

Search engines use the headings to index the structure and content of your web pages.

Users often skim a page by its headings. It is important to use headings to show the document structure.

<h1> headings should be used for main headings, followed by <h2> headings, then the less important <h3>, and so on.

For example:

  • <h1> - Page title
  • <h2> - Section titles
  • <h3> - Sub-sections

Example

<h1>Travel Guide</h1>

<h2>Europe</h2>
<h3>France</h3>
<h3>Italy</h3>

<h2>Asia</h2>
<h3>India</h3>
<h3>Thailand</h3>

Tip: Use only one <h1> per page - it represents the main topic or title.

Note: Use HTML headings for headings only. Don't use headings to make text BIG or bold.



Bigger Headings

Each HTML heading has a default size. However, you can specify the size for any heading with the style attribute, using the CSS font-size property:

Example

<h1 style="font-size:60px;">Heading 1</h1>


HTML Tag Reference

W3Schools' tag reference contains additional information about these tags and their attributes.

Tag Description
