This directory contains all CSS files for all of the theme variants. Which of the files are used is controlled by conf/css-files.xml file. For information please refer to the README.txt in the conf directory. We use the Less CSS precompiler (http://lesscss.org/) for creating our CSS files. The source Less files are also included. If you want to customise the stylesheet we strongly recommanded to use Less. To customise to styles make a copy of the Less file(s) you want to customize and create a new configuration file pointing to your files in conf. To make editing of the Less file(s) easier this theme also includes the Less compiler in the development mode. For production mode you have to compile the Less files to CSS as described in the Less documentation. The styles for this theme have been split into two Less files. The styles.less file contains all styles for the layout. The scicms.less file contains several variables which define several properties for the theme. Most of them are colours. At the end, the file includes the style.less file.
