The opposite of :hover
appears to be :link
.
(edit: not technically an opposite because there are 4 selectors :link
, :visited
, :hover
and :active
. Five if you include :focus
.)
For example when defining a rule .button:hover{ text-decoration:none }
to remove the underline on a button, the underline shows up when you roll off the button in some browsers. I've fixed this with .button:hover, .button:link{ text-decoration:none }
This of course only works for elements that are actually links (have href attribute)
