The current way of indicating focus of elements in the panel does not work very well with a fully-transparent panel, a line at the bottom of the panel doesn't make too much sense if there is no real panel, but only the text and icons. To make the indicators look better in this case, switch to a pill-shaped background color to indicate the focus of items in the panel. For this to look good, there has to be a small black border above and below the background, this also requires increasing the height of the panel (from 1.86em to 2.2em) for visual purposes. Also, since we now no longer need to color the lower bottom of the panel, we can remove the custom drawing code for the border of the panels corner, so do that.

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.
