Different Link States
You have probably noticed that links often have different styles attached to different states. When you hover over a link it will look different. Links that you have visited often look different. Sometimes a link will look different as you are pressing it. The different link states are:
Link (a:link ) - the default link
Typical Link Styles
At minimum, most developers will choose to get rid of the underline and change the font color for the different link states. Often they might also change the font-family and the font-weight. Most often, each state is identical except with a different text color and/or background color:
a:link {text-decoration: none; color: cadetblue; font-weight:bold;}
However you choose to style your links, make sure that they look different from the rest of your text. Font-weight, color, and the font-family should all work together to create a distinct style. Your links should coordinate and compliment the rest of your design, while still looking unique.
