Support for CSS Flyout Menu

#categoriescssHeading.leftBoxHeading {
background-image: url('includes/templates/classic/buttons/english/boxhead-categories.gif');
}

Thank you, But that STILL gives the resultant website "source code" of:
<div class="leftBoxContainer" id="categoriescss" style="width: 150px">
<h3 class="leftBoxHeading" id="categoriescssHeading">Categories</h3>

Thanks anyway,
Danny
