I'm working on a free HTML5 template, and all is going well, apart from the fact that I can't work out why each of the accordion sections is a set height (apart from the 1st one which is automatically selected - if you click on the sections below that, they are all a set height).

This is the page:

I've inspected the element with Firebug, and it shows the height is 326px, but when I look through the CSS, there is no mention of that value, or anything setting the height of the accordion.

I'd like to just have the accordion sections to take the height of the content inside them, but can't see how to do it.

Any advice much appreciated.
