As a demonstration that the first snippet does work for at least some apps on my 17.10 system, please find attached a screenshot showing part of a gedit window loaded after making gtk.css look like this:
decoration { border: 10px solid shade(@border-grey, 1); background: shade(@border-grey, 1); } I'm 99% sure I already tried "terminal-window" as the selector but I'll give it another go in a little while when I haven't got a lot of work in progress. It doesn't show any effect after saving the gtk.css and running "gnome- terminal --disable-factory", nor by restarting gnome shell with alt-F2 and "r", but I've found those are sometimes not enough to make gnome- terminal see changes, and will have to try fully logging out. ** Attachment added: "gedit with a 10px grey border" https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1736084/+attachment/5018078/+files/border.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1736084 Title: Unable to style borders on gnome-terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-terminal/+bug/1736084/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
