Basically I am using this gtk.css file in ~/.config/gtk-4.0/gtk.css but it’s weird that the sidebar is not themed correctly. If anyone knows about this, please do tell. My only lead at this moment is to find the class and add it in gtk.css file. For some reason I can’t install the gtk inspector app, So if anyone has it already or knows the classname, please help.
gtk.css file ->
@define-color accent_color #fe8019;

Sidebar ->
Defining sidebar_bg_color does not work?
@define-color sidebar_bg_color @define-color sidebar_fg_color @define-color sidebar_backdrop_color @define-color sidebar_border_color @define-color sidebar_shade_color @define-color secondary_sidebar_bg_color @define-color secondary_sidebar_fg_color @define-color secondary_sidebar_backdrop_color @define-color secondary_sidebar_border_color @define-color secondary_sidebar_shade_colorGTK Inspector comes with GTK, you don’t need to install it.
Enable it with gsettings
gsettings get org.gtk.Settings.Debug enable-inspector-keybinding trueso you can invoke it either by running
GTK_DEBUG=interactive application-name-hereor, when alredy using the application, via Control + Shift + I/Control + Shift + DThat’s it. Thank you for this.
You’re most certainly welcome.
I wanted to add on this, for anyone else stumbling across this post and struggling with sidebar theming: The above will work 90% of the time, but in case your
some-random-theme.cssoverrides_, or doesn’t follow the naming convention to begin with, search your gtk.css for.sidebar-pane, which should be the actual css selector for_, and.content-panefor-sidebar_.Gotcha. One last thing. Do I need to define helper colors as well? currently I am not doing that, but it is defined in the adw styleguide. Ain’t no way gruvbox has that much color varieties so what’s your suggestion?
Nah, unless you’re unhappy with the current outcome, you can leave it as it is.
Changes in
.config/gtk-4.0/gtk.csswill be applied on top of the stylesheet, so whatever you don’t override there, will fall back to the default, that’s why your sidebar previously went full Adwaita light mode.After taking a brief look at the libadwaita source, as far as I can see, helper colors are a special case anyways,
as well asborder_coloris used exclusively in thescssfiles (which the gtk.css is generated from), whereas the gtk.css for some reason doesn’t get back to the generic name, but uses the assigned valuealpha(currentColor,0.15)- which doesn’t help your case at all.To actually change @borders, you would need to modify its value in .scss and regenerate the .css then.
For your other point, there’s no need to introduce a new color for this, since the helper color is an alpha value derived from your foreground color (that’s what currentColor is referring to), so if you change
_fg_colorin gtk.css,will change along with it.Alright. Thank you so so so much.
I got the same issue, I was using Gradience to set gtk3/4 themes and that panel never got themed. Apps like Overskride have this issue too. I already had my preferred apps themed correctly so I did not bother.

Oh, I had this issue but I never solved it, I just had other apps that did not have this particular sidebar type. you should probably try to solve the GTK inspecrtor issue mentioned in one of the comments.
Gotcha.
