jquery - Stopping fixed position scrolling at a certain point?

Question

I have an element that is position:fixed and so scrolls with the page how i want it to however. when the user scrolls up I want the element to stop scrolling at a certain point, say when it is 250px from the top of the page, is this possible? Any help or advice would be helpful thanks!

I had a feeling that I would need to use jquery to do so. I tried getting the scrolling or location of the where the user is but got really confused, is there any jquery solutions?

Do you mean sort of like this?

http://jsfiddle.net/b43hj/

$(window).scroll(function(){
    $("#theFixed").css("top", Math.max(0, 250 - $(this).scrollTop()));
});

$(window).scroll(function(){
    $("#theFixed").css("top", Math.max(0, 100 - $(this).scrollTop()));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<div id="theFixed" style="position:fixed;top:100px;background-color:red">SOMETHING</div>

<!-- random filler to allow for scrolling -->
