How to Change Background When You Pass a Certain Point on Page using jQuery
<p>I have a sidebar and the various sections on a page. The sidebar floats left and the sections float right. I would like the sidebar color/background to change when it passes each section, so when it is on the first section it is red, second section blue and third section green. I have attached an example with the HTML/CSS. If someone could help me fill in the jQuery, that would be awesome.</p>
