 * Hey, this may not be the best place for this, but maybe someone can help me out
   quick. I am using the following for a drop down category menu in my archive page.
   All I want to do is make the width 100% in css. Is there a way to add a css class
   to this at all? Or, any way to change the width in pixes of the box? As it stands,
   it’s as wide as it needs to be. Thanks!
 *     ```
       <script type="text/javascript"><!--
           var dropdown = document.getElementById("cat");
           function onCatChange() {
       		if ( dropdown.options[dropdown.selectedIndex].value > 0 ) {
       			location.href = "<?php echo get_option('home');
       ?>/?cat="+dropdown.options[dropdown.selectedIndex].value;
       		}
           }
           dropdown.onchange = onCatChange;
       --></script>
       ```
