Div 100% height scroll

问题:

At my page i have a navigation bar to the left that is 100% height and 25% width. It is working fine, but when there's scroll available, it destroys the background, and make it look ugly. The reason i think is that 100% height is only applied to the active window. What is the trick to have a div 100% height always, even if the user is scrolling?

Css of the navigation:

    width:25%;
    height:100%;
    float:left;
    color:#999999;

I have tried position:absolute with no results, also tried clear both. Need help :)

Using min-height: 100% instead of height: 100% should fix it. See updated fiddle here: http://jsfiddle.net/zitrusfrisch/Sa6cb/3/
