$(document).ready(sizeContent);
    $(window).resize(sizeContent);
    function sizeContent() {
        var newHeight = $("html").height() - $("#subtract-all-other-divs").height() + "px";
        $("#the-div-you-need-100%-height").css("height", newHeight);
}

Declare html, body {height: 100%} in your css. Subtract all divs with a given height, such as a header, navigation and a footer. Like this: "#header" - "#navigation" - "#footer" + "px". Then add the element you need at 100% height.

Jquery: 100% Height (html, body)
