What does this mean?
All controls on the page - including links, buttons, and fields - should show when they have been selected by the keyboard.More help
You can confirm this yourself by loading a webpage and using the Tab key to navigate through it. Anything you can select should alter its appearance when selected. For example, a text field might change color, or have a distinctive border applied.
This is default behavior for all standard web controls, and so if this issue is appearing it is because this default behavior has been disabled. Or alternatively, if you have written your own custom controls, these will need styling to support focus states.
To comply, links and form controls typically define an
outline CSS style, which ensures
they are highlighted automatically, for example:
input:focus (outline: 2px solid red);
If you choose to override or disable the default
outline, you should specify an accessible
alternative, such as a border or background color.
