CSS Menus – Horizontal Drop Down CSS Menu

Sometimes a normal horizontal menu is not enough to satisfy the customer. Recently I designed a web site which contained anchor links to several different sections on the page. I placed links to all the sections at the top of the page. After almost completing the site, he asked if that page could be changed to have a horizontal drop down menu. Instead of creating a DHTML menu I decided to build it with CSS and a little javascript (to make it correctly in IE 6).


The beauty of this type of menu over other menus is that it has clean code, is fast loading, accessible, and search engine friendly.

Here’s the web site showing the CSS horizontal drop down menu

JAVASCRIPT

Javascript has to be added to make the site also render well in IE6.
I placed the code displayed below in an external file (folder named js) between the header tags.


<script type="text/javascript" src="js/dropdown.js"></script>


startList = function() {
if (document.all&&document.getElementById) {
navRoot = document.getElementById("nav");
for (i=0; i<navRoot.childNodes.length; i++) {
node = navRoot.childNodes[i];
if (node.nodeName=="LI") {
node.onmouseover=function() {
this.className+=" over";
  }
  node.onmouseout=function() {
  this.className=this.className.replace (" over", "");
   }
   }
  }
}
}
window.onload=startList;

Tip

I had to adjust the padding and margins for the menu and navbar styles to precisely position the css drop down so it rendered correctly in Internet Explorer and Firefox browsers.
