Alternating row colors in tree views

Support Developer

Is it possible to get the alternating colors of the rows in tree views?

The webclient does it but for the desktop client it is the responsibility of the Theme (see https://developer.gnome.org/gtk3/stable/GtkTreeView.html#GtkTreeView--rules-hint).

I’m interested in the desktop client.
What you need to set in the Theme to have zebra striping?

It is not possible to customize this behavior with CSS theme:https://gitlab.gnome.org/GNOME/gtk/-/issues/581
So the only way is to find a theme that implement it.

What about the grid lines color? Is it possible to customize this behavior with CSS theme?
And where you can find GTK theme with zebra striping?
