XFCE panel increase length of window buttons

In the XFCE bottom bar I notice even when I have free space the window buttons do not expand in size which makes them hard to read.  Here is how to make the window buttons in the taskbar bigger in XFCE

Create file

~/.config/gtk-3.0/gtk.css

add this line

.tasklist { -XfceTasklist-max-button-length: 500; }

restart the panel with this command

xfce4-panel -r
