I need to hide a background element in my css for IE.
This is the class in the css file
.navbar-header .nav #presentacion {
    background:url("../img/horiz-line.png") no-repeat scroll 108px 20px transparent;
    display: block;
    height: 20px;
    margin-top: 20px;
}
I want to use this method, inserting the CSS in the head section of the page hidding this part :
    <!--[if IE]>
          <style>
         .navbar-header .nav #presentacion {
         display: block;
         height: 20px;
         margin-top: 20px;
         background: none;}
    </style>
   <![endif]-->
It's not working , the background is still displayed in IE, what i am doing wrong?
