Joonas Henriksson c17dc9c8ec theme: Rotate placeholder for horizontal workspace-thumbnails
On the new horizontal workspace-thumbnails, the old placeholder from
vertical dash appeared too small, and was easily hidden behind the
dragged window/icon. Rotate the placeholder 90 degrees to better fill
the spacing between thumbnails.

Summary

Do not edit the CSS directly, edit the source SCSS files and the CSS files will be generated automatically when building with meson + ninja and left inside the build directory to be incorporated into the gresource XML (you'll need to have sassc installed).

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:

File Description
_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 on its web page. Once you make your changes to the _common.scss file, you can run ninja to generate the final CSS files.
