If you use multiple landmarks of the same type, give them unique labels (names).

The color contrast between text and its background meets WCAG AA contrast ratio.

Only use ARIA attributes that are permitted for the element's role.

Every <button> needs a visible label or accessible name.

The complementary landmark <aside> or role="complementary" should be a top-level region, not nested in another landmark.
