层一样用法:    <div style="width:400px; height:100px; background:url('http://community.csdn.net/Images/ad/120-60_050526.gif')" 
onmouseover="this.style.background='url(http://www.google.com/images/logo_sm.gif)'"
onmouseout="this.style.background='url(http://community.csdn.net/Images/ad/120-60_050526.gif)'">
    </div>
