How to Add a Column Header and Footer Options

[itKiwi]

I'm new at this CSS, and have plagiarised some code off the 'net. See attachments. I don't really understand all of what's happening in this page, but I now want to add the itemheader and itemfooter classes. The itemheader should be level with the top of the image, and the itemfooter should go under the existing text, in the same column. Both these could be in a different text style, and/or links. I need to repeat variations of this "item" group down the page.

Also, how can I get the text to expand and contract to fill the available width, and not jump under the picture.

I'm using Firefox 1.5 for development, but it must also work with IE6.

Your help would be appreciated. Thanks.
