Non-text contrast

What the issue is

Buttons that lack clear keyboard focus indicators make it difficult for users who rely on keyboard navigation to determine which element has focus. This issue typically arises in custom-styled web pages where the default focus styles provided by browsers have been overridden or removed. Without visible focus indicators, keyboard users may lose track of their current position on the page, leading to a frustrating and inefficient navigation experience.

What the issue is

Buttons that do not provide visual feedback when interacted with (e.g., via mouse hover, focus, or activation) can cause confusion and uncertainty for users. Visual cues such as changes in color, elevation, enclosing box,  or animation help indicate that a button can be interacted with and has indeed been activated or is currently focused. Without these cues, users, especially those with visual impairments or cognitive disabilities, may struggle to understand whether their actions have been registered.

What the issue is

Language selectors can fail colour contrast requirements when the text or graphical objects do not provide enough contrast against their background. This makes it difficult for users with visual impairments, including those with color vision deficiencies, to discern the options or current selection within the language selector widget.
