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 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.
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>
