CMS Help making 1x2 right side and left article previews to match height?
 

I have a background color and border around my previews in the CMS, but the right and left side previews don't match in height on a 1x2 page. I would like them to match.

I set div.article_preview to have a height:100% and I also set .leftcol and .rightcol to both be height:100%, so I feel like the side by side previews on a 1x2 page should both match at 100% of the height of the .fullwidth div/box they are in.

What am I missing?
