Front End Development for AJAX site build based on Drupal 7
For years now web designers and developers have been utilising the :hover pseudo class to add life to their website or project. This is quite a common convention and is tradionally used to give hyperlinks diffferent states, but is not restricted to use just on hyperlinks (apart from say older browsers) .
The :hover selector is used to select elements when you mouse over them.
Tip: The :hover selector can be used on all elements, not only on links.
