we added GTK3 now to support GTK3 application theming under XFCE.
The easiest way to download and apply GTK3 themes under XFCE is to try the Opendesktop app:
Just give it a shot and let us know how it works.
Thanks for introducing gtk3 on xfce-look.org. As for the app, i’m old school, i hate apps, i like it in the browser
I know this is an old topic , but I find it misleading.
Not every GTK3-theme supports XFCE. So simply copy the main GTK3-category to XFCE-look.org is not really a good idea. As a themer myself I have adapted a few themes specific for XFCE. And I could not really find the correct category to put it in, because it is both GTK2/GTK3 and XFWM4, with specific CSS-code to make it work properly in the XFCE-desktop.
