Use header elements to convey document structure and use them according to specification.

Checkpoint 3.5

"Identifying what is structure and what is presentation may be challenging at times. For instance, many content developers consider that a horizontal line communicates a structural division. This may be true for sighted users, but to unsighted users or users without graphical browsers, a horizontal line may have next to no meaning. For example, in HTML content developers should use the HTML 4.01 [HTML4] heading elements (H1 - H6) to identify new sections. These may be complemented by visual or other cues such as horizontal rules, but should not be replaced by them." [12]
