Make sure that everyone can navigate and interact with the same content and components. Can people operate this content with whatever capacity they have?
2.4.4 Link Purpose (In Context)
A link’s destination should be clear from either the link text itself or the surrounding sentence context.
2.4.5 Multiple Ways
Header navigation is not the only way to get around a website; there’s another way, such as on-page links, a sitemap, or a site-wide search.
2.4.6 Headings and Labels
Headings are descriptive of the content that they contain, form labels clearly describe what information is required, and buttons inform the user what will happen when they’re pressed.
2.4.7 Focus Visible
There’s visible keyboard focus styling to indicate which element you’re currently focused on.
2.4.8 Location
The user is clearly informed where they are in a set of pages.
2.4.9 Link Purpose (Link Only)
It is clear where a link will take you from the link text alone, without having to read the text around it.
2.5.1 Pointer Gestures
All actions that are carried out using a gesture (swiping, pinching, and so on) or drawing, can also be done with a button or buttons.
2.5.2 Pointer Cancellation
Actions (like pressing a button) aren’t triggered on mouse-down; rather on mouse-up.
2.5.3 Label in Name
The visible text of a form field, button, or link matches the text in the underlying code.
2.5.4 Motion Actuation
There is no reliance on device motion, like shaking or tilting, to carry out an action.
