Parts of the Extranet's design/layout can be customized. This is done by uploading a new stylesheet with the Upload style sheet button.
The format of the style sheet file usually ends with the extension .css.
To get some inspiration, you can download the original stylesheet from her: http://system.microbizz.dk/gfx/xnet/style.css
You can also choose to add a custom logo and colors to your pages in the Extranet:
The Reset to standard button resets your design's logo and colors to the standard ones.
Finally, you can add and create files with the Add file and Create file, respectively, making them always available to be used within your Extranet design.
