Hi. I'm using fedora 16 (gnome shell) 64 bit. I was wondering how to change the GTK3 theme. I saw other forum posts on this topic but no working answers. I tried creating the .themes folder and putting the themes in there and unpacking theme (I downloaded them form deviantart). Any help would be greatly appreciated.
Download your theme, place it in your home directory in a folder called ".themes", and then install Gnome-tweak-tool (see illustration) then run the tweak tool "Advanced Settings" and select your theme elements there.
