The Numix theme is available by installing
shimmer-themes from the software center. It is installed by default in Xubuntu.
In 14.04, I was able to modify some aspects of the theme by directly editing files such as
Even in 15.10, the solution as described in How to set a custom text highlighting colour could be easily applied.
But in 16.04, the same approach does not seem possible. I looked at the
README.md file in the developer's page here: https://github.com/numixproject/numix-gtk-theme. A couple of quotes from there:
If you want to hack on the theme, make sure you have the inotifywait command available, which is used for watching and automatically building the files.
If you change any assets, you'll need to regenerate the gtk.gresource.xml and gtk.gresource files. You can use grrr to do it easily.
So how can a normal, average user change any aspect of the Numix theme available for 16.04? Can someone familiar with gtk3 themes that use
scss rather than only plain
css please explain the procedure?
