Center Box Borders

I have searched for hours and not found and answer to this. I am trying to have the borders of my center boxes hang down from the center box header image just like my side boxes do.

See the base template here: http://www.wilpackpackaging.com/shoponline

Specifically the "New Products Center Box"

The borders extend up past the image. I know that I need to redo the image so that it is square at the bottom but I will fix that later.

I have tried adding the border to .centerBoxContents, however, that puts a box around each individual item within the centerBoxWrapper.

For some reason, the centerboxcontents is plural and not a centerboxcontent like the sideboxcontent

Any help on this issue would be greatly appreciated. If I have left any necessary information out, please let me know.

Thanks in advance.

Well with no assistance and no ability to find any solution in any other threads, I have done a work around.

I took out the side borders and put in a background color. Then I made sure that the images used for the header had a white background color behind the rounded corners. This give the appearance of a box that hangs from the header.

Until the coding separates the content box from the contents boxes then I cannot see another way to accomplish this. And I cannot find any tutorials or thread on how to add an all encompassing content box.
