When using paragraph styles in RCE, can I use the header 3 more than once? Do the headings need to be in order? I appreciate any help with this
For accessibility and usability purposes, headers should be nested properly. You should not go directly from an H2 to an H4. You can use any of the headers multiple times, though.
The Headings • Page Structure • WAI Web Accessibility Tutorials states:
Skipping heading ranks can be confusing and should be avoided where possible: Make sure that a <h2> is not followed directly by an <h4>, for example. It is ok to skip ranks when closing subsections, for instance, a <h2> beginning a new section, can follow an <h4> as it closes the previous section.
Some people hold design philosophies that are different about how many levels of headings you should use. Tufte CSS states:
Tufte CSS uses h1 for the document title, p with class subtitle for the document subtitle, h2 for section headings, and h3 for low-level headings. More specific headings are not supported. If you feel the urge to reach for a heading of level 4 or greater, consider redesigning your document:
If you're following that design principle, then you would certainly need to use a level-3 heading more than once.
