`bundle install` command on fedora 21 was failing with following message: Your Gemfile has no gem server sources. If you need gems that are not already on your machine, add a line like this to your Gemfile: source 'https://rubygems.org' After adding that line it worked again. https://bugzilla.gnome.org/show_bug.cgi?id=746205 |

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 sofwtare installed, as described below)
* To be able to use the lates/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
----------------------
Adwaita is a complex themes, so to keep it maintainable it's written and processed in SASS, the
generated CSS is then transformed into a gresource file during gtk build and used at runtime in a
non-legible or editable form.
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 This is done by running `bundle exec sass --watch --sourcemap=none .` If sass is out of date, or is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`.
