Understandable

People with disabilities must be able to understand your content and use your interfaces.

When creating an HTML page with body copy in English, your HTML tag will include a language declaration. <html lang="en">.
Use the lang attribute every time screen readers should change pronunciation.

Use plain language

No unexpected changes in context

Change in context: To avoid disorienting users, the following should happen only when the user initiates a change by interacting with an interface element:

  • Opening a new window
  • Loading a new page
  • Significantly rearranging page content
  • Moving focus to a new component.
Make errors easy to spot and correct
