How do I use scrollTop when trying to figure out sidebar position?
<p>I posted this <a href="http://stackoverflow.com/questions/6539926/how-do-i-get-the-sidebar-to-move-up">question</a> yesterday and the answer I go mentioned that I should check if scrollTop is higher than your header height. My question is how do I do this with query. How do I do this when different people have different screen sizes</p>
