Managing Focus

it's an extremely important technique that keeps the user's interactive context in sync with the visual representation of the site.

You can skip ahead to Lesson 6 to learn how to change or remove the focus ring from an element. In this case, since we're managing focus and headers are typically not interactive it's probably OK to remove their focus ring. However, you should never remove the focus indicator from an interactive element unless you're going to replace it with something else. Otherwise a keyboard user might have no idea which element is currently focused!
