Headings organize text into a hierarchy of sub-headings, with <H1> being the highest level of heading. You can have up to six levels of headings and sub-headings within a single document.

The different headings look like this in relation to each other in a home page file:

<H1> Heading 1 </H1>

Heading 1

<H2> Heading 2 </H2>

Heading 2

<H3> Heading 3 </H3>

Heading 3

<H4> Heading 4 </H4>

Heading 4

<H5> Heading 5 </H5>

Heading 5

<H6> Heading 6 </H6>
