h1

I. Description

The HTML h1 element contains the title for the webpage. There should be only one h1 element on each webpage.

There are six different levels of headings which may appear on a webpage, the six different heading levels are (from most important to least important) h1, h2, h3, h4, h5, and h6.

There may be multiple instances of h2, h3, h4, h5, and h6 on a given webpage.

Heading levels should not be skipped. Meaning that if there is at least one h1 element and one h3 element there should be at least one h2 element. Omitting a heading level (eg, going from h2 to h5 with no heading levels in between) is considered to be improper.
