Here's a screen shot. What does the lime-green shading signify?
Update: Thanks for all the help -- I figured out what to do not only with the extra vertical space but with the help of Firebug, I now understand why text on the index pages was indented under the headings. I didn't want it indented. So I created a new class "showForIndexPage" and use it in place of "show" on the index pages. It has much more modest horizontal padding.
Things are starting to line up the way I want them to.
