       Gradients are images that smoothly fades from one color to another. CSS
       provides ways to specify repeating and non-repeating linear and radial
       gradients. Radial gradients can be circular, or axis-aligned ellipses.

       GTK+ has extensive support for loading icons from icon themes. It is
       accessible from CSS with the -gtk-icontheme syntax.
