<body>
    <div id="testDiv">And here is my very slick menu!</div>
    <a href="#" onClick="toggle_visible()">Toggle</a>

The div should look like this if you want it to be hidden in the first place.

<div id="testDiv" style='visibility:hidden'>

You need to toggle the rendering and not visibility. Even invisible elements takes up space on the page. Use the "display" property to create invisible elements that do not take up space.

<div id="testDiv" style="display: none;">Content</div>

It worked.......thank you so much....u helped me big time......i cant believe i dint try that tho......but anywayz thanks alot.....
