This is about the new Apertus website, located at http://dev.apertus.org.
Its still in developmet but once finished will replace the current main website which will be archived (but stay online in a rea-only mode)
Drupal 7 install, with the twitter bootstrap theme.
There is a subtheme, called "apertus_bootstrap" which is in use now.
In this theme there is an apertus.css file.
Please try to respect the structure of this file:
It makes it easier to find your way. General rule: as little css as possible, only override what is needed. Ask for help, make backups.
