Scrollbar on div which has a height of 100%

I've been looking around but I can't figure out how to have scroll bars on a div only which has a height of 100%. With a set height, this works fine:

overflow-y:scroll;

However with 100%, the scrollbar appears on the div, however doesn't extend; instead the window has scroll bars. From what I've seen, I have tried: http://stackoverflow.com/questions/6499624/div-height-100-with-scroll-barhttp://stackoverflow.com/questions/14355957/div-with-100-height-having-no-browser-scrollbarshttp://www.sitepoint.com/forums/showthread.php?390159-Need-an-overflow-scrollbar-on-a-div-with-100-height but none of these have any affect.

body, html{margin:0; padding:0; height:100%; overflow:hidden;} #content{background-color:#FF6633; height:100%;overflow-y:auto; width:960px; margin: 0 auto; } it becomes a little complicated if you have headers and footers, as you have to allow for these, as these will force the #content outside the 100% height of browser window.
