How can I change the background color between the tiles?

[Hirls1720]

I tried to customize my Tilix to look more appealing, but Tilix doesn't have an option to customize the background color of the space that separates the tiles.

Thanks

It depends on the GTK theme you are currently using.

[algj]

GTK_DEBUG=interactive tilix --new-process to launch a debugger, afterwards you can try out different CSS - you need to apply it to your main GTK theme after tinkering, this cannot be done over debugger, it's only for preview!
