title: Determine distance from the top of a div to top of window with javascript
body: <p>How do I determine the distance between the very top of a div to the top of the current screen?  I just want the pixel distance to the top of the current screen, not the top of the document.  I've tried a few things like <code>.offset()</code> and <code>.offsetHeight</code>, but I just can't wrap my brain around it.  Thanks!</p>
