Submit Button Rollovers

[Pachman3000]

Hey Guys,

 

I'm using this CSS for my button rollovers.

 

.lrollover a{

  cursor:pointer;

  display:block;

  margin:auto;

  outline:0 solid transparent;

  text-indent:-9999px;

}

 

#l_button a {

  background:url("images/btn_login.png") no-repeat scroll left top transparent;

  height:32px;

  width:100px;

}

 

#l_button a:hover {

  background-position:left -32px;

}

 

 

 

I can't seem to get these rollovers to work for the submit buttons on my forms.

 

I've been playing around with this

              <input type="submit" value="" class="lrollover"  id="l_button"/>

 

 

Any help would be awesome!
