[xwiki-users] Use of color theme styles

Hi, I would like to use the container macro and three collums {{container layoutStyle="columns"}} (((first content))) (((second content))) (((third content))) {{/container}} The contents would be includes from three pages containing Header level 5, a link to another wiki page, a short descriptive and an image The question is that I would like these three columns to look like a collapsed panel header you get when you set a colortheme (new version with coloreffect) What is the way to include a DIV CSS selector with a class attribute similar to the collapsed header from colorthemes The result should be that all three columms will allign (same height, width) with the background fill and border like a collapsed panel header (regardless of content of the three included pages) Help will be greatly appreciated...
