I would like to change the background of panel's menu (and make it transparent) and change the color of the slider (from purple to orange). I like the default Ubuntu shell theme, so I don't want to use custom themes.
I also want to change the background of search text form (unfocused).
What are the classes/ids in gnome-shell.css? I tried but I didn't find them.
Another question is where can I find a default gnome-shell.css file? Until now I used files from custom themes but if I extract the .gresource file in /usr/share/gnome-shell/themes/ I don't get the default css.
