Do you pay attention to the :focus pseudo-class?
Quite probably you do use the :link and :visited pseudo-class, and also do some fancy styling on :hover and :active situations, but when was it that you’ve paid attention to the :focus?
What IS :focus you might wonder.
Focus comes into play when somebody uses the keyboard and not the mouse to navigate (by tabbing though) your site.
Implement it for example like this:
a:link, a:visited { color: brown; }
a:hover, a:focus, a:active { color: orange }
Very easy to add and it will make you site more accessible.
