Talk to the person who made this theme ??
(with a fixed height what else do you expect?)

I expected an answer, not some snide remark.

For the snippet question you can replace the_content with the_excerpt. As far as the fixed height issue, you’ll have to simply alter your theme some more. Here’s a great article that explains how to have your sidebar extent to the footer (or vice versa) without stuffing it with a bunch of content to simply push it down (or using a fixed height).

now, that’s a reply! thanks for your help!
