|
-------
|
||
|
|
|
||
|
|
* To be able to use the latest/adequate version of sass, install sassc
|
||
|
|
* meson will regenerate the CSS every time you modify the SCSS files.
|
||
|
|
* Note that meson always builds out-of-tree, so the modified css files will
|
||
|
|
appear in your builddir.

Theme variants
|
||
|
|
--------------
|
||
|
|
|
||
|
|
The Default theme comes in 4 variants: light, dark, hc (highcontrast) and
|
||
|
|
hc-dark (highcontrast inverse). The generated CSS files for the variants
|
||
|
|
are called Default-$variant.css. For technical reasons, GTK adds one level
|
||
|
|
of include wrappers around these, which are called gtk-$variant.css.
|
||
|
|
|
||
|
|
How to tweak the theme
|
||
|
|
----------------------
|
||
|
|
|
||
|
|
Default 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 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 Default 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, GTK will rebuild the CSS files.
