<solved> gtk theme parsing error

I'm running Debian 13.2 XFCE destop

Whenever I run YAD (and only when I run YAD) I get this annoying gtk error

(yad:4560): Gtk-WARNING **: 18:24:34.093: Theme parsing error: gtk.css:5:0: Expected a valid selector

I have no idea how to stop the warning and. would appreciate any effort to resolve this.

My /usr/share/themes/  is loaded with themes including `Default` theme

My ~/.config/gtk-3.0/gtk.css  contains :

scrollbar button {
    min-width: 10px;
    min-height: 15px; }

{
    -GtkScrollbar-has-backward-stepper: true;
    -GtkScrollbar-has-forward-stepper: true; }

scrollbar.vertical button.down {
    -gtk-icon-source: -gtk-icontheme("pan-down-symbolic"); }

scrollbar.vertical button.up {
    -gtk-icon-source: -gtk-icontheme("pan-up-symbolic"); }

scrollbar.horizontal button.down {
    -gtk-icon-source: -gtk-icontheme("pan-end-symbolic"); }

scrollbar.horizontal button.up {
    -gtk-icon-source: -gtk-icontheme("pan-start-symbolic"); }

Re: <solved> gtk theme parsing error

{
    -GtkScrollbar-has-backward-stepper: true;
    -GtkScrollbar-has-forward-stepper: true; }

This block is not valid because there are no identifiers specified. I believe you want:

scrollbar, .scrollbar {
    -GtkScrollbar-has-backward-stepper: true;
    -GtkScrollbar-has-forward-stepper: true; }
