How can I make a div stick to the top of the screen once it's been scrolled to?

Question

I would like to create a div, that is situated beneath a block of content but that once the page has been scrolled enough to contact its top boundary, becomes fixed in place

Answer 1

Here is another option:

JAVASCRIPT

var initTopPosition= $('#myElementToStick').offset().top;   
$(window).scroll(function(){
    if($(window).scrollTop() > initTopPosition)
        $('#myElementToStick').css({'position':'fixed','top':'0px'});
    else
        $('#myElementToStick').css({'position':'absolute','top':initTopPosition+'px'});
});

Your #myElementToStick should start with position:absolute CSS property.
