I'm doing some work on a theme and I'm using horizontal accordion scrollers.
You can see on my practice page that the three main sections (on the right) are all different sizes. The rightmost section has a big block of text but it is all cut off after 600px (which is what I have it set as).
Since this will be for a blog there will be different sized pages with every click but I can't seem to find a way to have the elements default the height based on the amount of content.
The accordion script uses MooTools and you can see everything I've done on my development page.
