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 usr/share/themes/Numix/gtk-3.0/gtk.css
or usr/share/themes/Numix/gtk-3.0/gtk-widgets.css
.
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.
and
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?
SASS
and notSCSS
(although SASS and SCSS use the same compiler). these are CSS preprocessors, so you write the code in SASS then run the compiler to produce CSS that can be used directly. the inotify command is likely used as a watcher to trigger compilation. You don't need to bother with all of this if you are just doing a few changes. its only really worth the hassle if you desperately want SASS capabilities and expect to maintain your work long term
