GTK+ switched from ruby-based sass to c-based sassc for performance reasons. It makes sense to follow suit, if not to not require two tools for the same job ... https://bugzilla.gnome.org/show_bug.cgi?id=783210

Summary
|
|
-------
|
|
|
|
* Do not edit the CSS directly, edit the source SCSS files and process them with SASS (running
|
|
`make` should do that when you have the required software installed, as described below;
|
|
run `./parse-sass.sh` manually if it doesn't)
|
|
* Most SASS preprocessors should produce similar results, however the build system
|
|
integration and 'parse-sass.sh' script use sassc. You should be able to install
|
|
it with `pkcon install sassc` or your distribution's package manager.

How to tweak the theme
|
|
----------------------
|
|
|
|
Adwaita is a complex theme, 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 from a handful of basics. It is an exact copy of the gtk+
|
|
counterpart. Light theme is used for the classic theme and dark is for GNOME3 shell
|
|
default.
|
|
|
|
_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 make or the ./parse-sass.sh script.
