Accessibility of headings
When used correctly, headings:
Separate – they identify and separate different sections and subsections, making it easy for users to find the relevant information.
Minimise – they break large blocks of text up into smaller sections, making content easier to digest.
Enable navigation – they allow users to keep track of where they are on the page, and help screen reader users navigate through content using a keyboard. The more content you have on a page, the more important it is to break up that content with headings.
