  • Hi everyone.

    I got for my website’s #navigation that turns the bar from “position absolute” to “position: fixed” in my css file after x amount of scrolling

    <SCRIPT type=”text/javascript”>
    /* Handles the page being scrolled by ensuring the navigation is always in
    * view.
    function handleScroll(){

    // check that this is a relatively modern browser
    if (window.XMLHttpRequest){

    // determine the distance scrolled down the page
    var offset = window.pageYOffset
    ? window.pageYOffset
    : document.documentElement.scrollTop;

    // set the appropriate class on the navigation
    document.getElementById(‘navigation’).className =
    (offset > 240 ? ‘fixed’ : ”);


    // add the scroll event listener
    if (window.addEventListener){
    window.addEventListener(‘scroll’, handleScroll, false);
    window.attachEvent(‘onscroll’, handleScroll);

    with css:

    #navigation {
    top: 240px;
    position: absolute;
    padding: 15px 0px;

    #navigation.fixed {
    top: 0px;
    background: white;
    border-bottom: 1px dotted #d9d9d9;

    This works brilliantly, but I wanna expand it and have my navigation links to previous/next post/page (#nav-single, #nav-loop, #nav-search) to be to the bottom of the window to move whilst scrolling until after 50% of window is scrolled of pixels to turn it into fixed at that position (50% from top or bottom, whichever)

    ive been playing around with the code for a good hour but I just cant seem to get it to work

    please help??
