In the beginning accessibility of the images in the tab rollers was a problem  now the problem has been cleared and the web developers have got joy everywhere after it is cleared, the rollovers involve in creating one image for each navigation which has got normal, hover and active states stacked on top of each other, and after that CSS will be used to change the background position and also to reveal each state at the appropriate time, when user use one image for each state permits the users to toss out ugly java script and for hover effects make use of simple CSS effects, using this way is very good it eliminates the flicker effect which is suffered by other CSS methods.

When the user wants to see the things happen well first he has to set up the rules that all navigation items will need, so when this is done before hand it saves the users from writing duplicate rules for each tab, after that they have to add a separate rule for each list item that is id giving it its own background image and width these vary the difference from each tab.
