Development considerations#
Heading hierarchy
While using the Display
component, take care of the correct heading hierarchy which can be adjusted through the tag
property. Keep in mind that the visual appearance must not always be identical with the semantic hierarchy.
Best practices
Use one unique h1
per page that describes what that page is about.
Use headings to describe the content below. Do not use an HTML heading just to make the text appear bigger or stand
out.
Use heading levels like the index of a book: hierarchical.
Do not choose a heading by its size, but by its level in the context of the content.
Heading hierarch should not increase by more than one level at a time.
Do not skip a heading level from the top down.
