Can someone help me take a look at this please,

Here is my css coding for the div class and also the html

CSS

```
#f1{
 width: 100px;
 height: 50px;
 left: 370px;
 top: 450px;
 background:black;
 position: absolute;
 opacity:0;
 filter: alpha(opacity=0);
 float: left;
 -webkit-transition: 1s all;
 -moz-transition: 1s all;
 transition: 1s all;
 }
#f1:hover {
 background:url(images/flavours/f1.jpg);
 width: 320px;
 height: 320px;
 opacity:100;
 filter: alpha(opacity=100);
 float: left;
 position: absolute;
 }

```

HTML

<div id="f1"></div>

```

The hover does not work for IE!
Many thanks in advance!
