Headings and Labels

Understanding WCAG2.0

Although it is easy to check about the heading of main content, there are occasions where a non-display headline is placed in the navigation portion other than the main text. It may be overlooked inadvertently as it is a hidden place, but please make sure to include the appropriate content. It is good to check off by turning off CSS.

Principle Operable User interface components and navigation must be operable.
Guideline Navigable Provide ways to help users navigate, find content, and determine where they are.
Criterion Headings and Labels
(2.4.6 AA)
The headings and labels explain the theme or purpose.
