XFCE semi-transparent desktop icons text background

To make the XFCE desktop icons text background semi-transparent (as opposed to fully transparent) create this file in the $HOME directory: ~/.gtkrc-2.0 and put the following in it:

style "xfdesktop-icon-view" {

XfdesktopIconView::label-alpha = 20

base[NORMAL] = "#ffffff"
base[SELECTED] = "#5D97D1"
base[ACTIVE] = "#5D97D1"

fg[NORMAL] = "#ffffff"
fg[SELECTED] = "#ffffff"
fg[ACTIVE] = "#ffffff"
}
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"

Log out and in. Now, there is a slight and non-obtrusive text background:

Hint is from here.
