Summary
-------

* Do not edit the CSS directly, edit the source SCSS files and process them with SASS (run 
  `./parse-sass.sh` when you have the required software installed, as described below)
* To be able to use the latest/adequate version of sass, install ruby, gem, sass & bundle.
  On Fedora F20, this is done with `sudo dnf install rubygems && gem install bundle && bundle install`
  from the same directory this README resides in.

How to tweak the theme
----------------------

Greybird is a complex theme (based on Adwaita), so to keep it maintainable it's written and processed
in SASS.

It is very likely your change will happen in the _common.scss file. That's where all the widget 
selectors are defined. Here's a rundown of the "supporting" stylesheets, that are unlikely to be the 
right place for a drive by stylesheet fix:

_colors.scss        - global color definitions. We keep the number of defined colors to a necessary minimum, 
                      most colors are derived form a handful of basics. It covers both the light variant and
                      the dark variant.

_colors-public.scss - SCSS colors exported through gtk to allow for 3rd party apps color mixing.

_drawing.scss       - drawing helper mixings/functions to allow easier definition of widget drawing under
                      specific context. This is why Adwaita isn't 15000 LOC.

_common.scss        - actual definitions of style for each widget. This is where you are likely to add/remove
                      your changes.
                      
You can read about SASS at http://sass-lang.com/documentation/. Once you make your changes to the
_common.scss file, you can either run the ./parse-sass.sh script or keep SASS watching for changes as you
edit. This is done by running `bundle exec sass --watch --sourcemap=none .` If sass is out of date, or is
missing, you can install it with `bundle install`.
