Reposition Div After Scrolling

I have a navigation bar that repositions after scrolling down. It works with position:fixed, but while scrolling I want it to move up like all the other content that follow on the

Solution 1:

In the first look i think it's impossible but after some tries this code was created. I spent long time to write this code and use several techniques and hope to be helpful. Maybe there are simpler solutions too !!

var bitFlag = false;
var lastScrollTop = 0;
var timeoutId;
$navigation = $("#navigation");
$(window).scroll(function (event) {
    var intWindowTop = $(window).scrollTop();
    var intElementBottom = $navigation.offset().top + $navigation.innerHeight();
    if (intWindowTop > lastScrollTop) {
        if (!bitFlag) {
            $navigation.css("position", "absolute").css("top", intWindowTop + "px");
            bitFlag = true;
        }
        if (timeoutId) {
            clearTimeout(timeoutId);
        }
        timeoutId = setTimeout(function () {
            if (intWindowTop > intElementBottom) {
                intDelayTime = setTimeout(function () {
                    $navigation.animate({
                        top: intWindowTop + "px"
                    }, 800);
                }, 500);
            }
        }, 100);
    } else {
        $navigation.css("position", "fixed").css("top", "0px");
        bitFlag = false;

    }
    lastScrollTop = intWindowTop;
});

The }, 500); section control Delay time in milliseconds and the }, 800); section control the slide down animation speed.
