HTML5 Notes For Professionals

Using Headings.

Headings can be used to describe the topic they precede and they are defined with the <h1> to <h6> tags. Headings support all the global attributes.
• <h1> defines the most important heading.
• <h6> defines the least important heading.
Defining a heading:
<h1>Heading 1</h1>
<h2>Heading 2</h2>
<h3>Heading 3</h3>
<h4>Heading 4</h4>
<h5>Heading 5</h5>
<h6>Heading 6</h6>
Correct structure matters
Search engines and other user agents usually index page content based on heading elements, for example to create a table of contents, so using the correct structure for headings is important.
In general, an article should have one h1 element for the main title followed by h2 subtitles - going down a layer if necessary. If there are h1 elements on a higher level they shoudn't be used to describe any lower level content.
