html - Image under anchor tag onmouseover highlighted background color not changing -

here code onmouseover on image under anchor tag highlighted color not changing please can know doing wrong

 <div class="iconlink">   <a href="/classification/classificationlabel" title="classification label">   <img src="/content/images/labels-72x72.png" /><div>classification label</div>      </a>     </div> 

i tried these types

.iconlink a:hover {background-color: #000000;     color: #000000;0} 

and

<div class="iconlink">   <a href="/classification/classificationlabel" title="classification label" class="hove">  <img src="/content/images/labels-72x72.png" /><div>classification label</div>   </a>    </div>  .hove:hover{background-color: #000000;     color: #000000;} 

you need apply background-color img in css like:

.iconlink a:hover img {   background-color: #000; }  .iconlink a:hover {   color: #000; }
