I made a very simple and lightweight content style to use in virtualmin called iziDesign. A working sample is at http://izihost.biz It has a page with a CSS based formular and a page with a table
If you like it then Download at http://izihost.eu/downloads/iziDesign.zip Unpack and upload the folder iziDesign to the server keeping the directory structure intact to /usr/libexec/webmin/virtual-server/styles (RHEL/CentOS/Fedora/SuSE/Mandriva) or /usr/share/webmin/virtual-server (Debian/Ubuntu).
It is free to use however donations for the effort are always welcome and highly appreciated. See style-license.txt The .psd for the logo is included, simply edit or replace with your own (recommended)
If you want the column on the right then in the style.css change the float:left to float:right at the #left selector and if necessary the float:right to float:left on the #right selector
ohhhhh nice !!!
