Page Title
Use this sentence to briefly describe the purpose of the page.
Level 2 Heading (H2)
The page heading communicates the main focus of the page. Make your page heading descriptive and keep it succinct.
Level 3 Heading (H3)
These headings introduce, respectively, sections and subsections within your body copy. As you create these headings, follow the same guidelines that you use when writing section headings: Be succinct, descriptive, and precise.
Use the side navigation menu to help your users quickly skip to different H3 and H4 sections of your page. The menu is best suited to displaying a hierarchy with one to two levels and, as we mentioned, to display the sub-navigation of a given page. Keep each section and subsection focused — a good approach is to include one theme (topic) per section.
