Enlarge scroll bar width - how to

Support Xfce
2

Create the file ~/.config/gtk-3.0/gtk.css if it doesn’t already exists and paste the following CSS rules in it:

scrollbar, scrollbar button, scrollbar slider {
    min-width: 10px;
    min-height: 10px;
}

The min-width value is for the vertical scrollbar and the min-height value is for the horizontal scrollbar. You can change the values according to your liking.

After saving the file, you have to logout/login in order to see the changes.

Bare in mind that the above CSS rule will change the scrollbars in all Gtk-based applications, not only the two you’re mentioning.
