I have a search box, and I wanted to use a flash submit button, that has a hover behavior, so I made this button: <div class="search_button"><a href="#"></a></div> .search_button a { width:29px; height:20px; background-image:url(images/v7/v7_r13_c5.jpg); display:block; } .search_button a:hover { width:29px; height:20px; background-image:url(images/v7/v7_r13_c5.jpg); background-position:0px 21px; display:block; } Code (markup): How can I make it act as a form submission button?
