-- GtkCssProvider is an object implementing the t'GI.Gtk.Interfaces.StyleProvider.StyleProvider' interface.
-- It is able to parse [CSS-like][css-overview] input in order to style widgets.
-- 
-- An application can make GTK+ parse a specific CSS style sheet by calling
-- 'GI.Gtk.Objects.CssProvider.cssProviderLoadFromFile' or 'GI.Gtk.Objects.CssProvider.cssProviderLoadFromResource'
-- and adding the provider with 'GI.Gtk.Objects.StyleContext.styleContextAddProvider' or
-- 'GI.Gtk.Objects.StyleContext.styleContextAddProviderForScreen'.
-- 
-- In addition, certain files will be read when GTK+ is initialized. First, the
-- file @$XDG_CONFIG_HOME\/gtk-3.0\/gtk.css@ is loaded if it exists. Then, GTK+
-- loads the first existing file among
-- @XDG_DATA_HOME\/themes\/THEME\/gtk-VERSION\/gtk.css@,
-- @$HOME\/.themes\/THEME\/gtk-VERSION\/gtk.css@,
-- @$XDG_DATA_DIRS\/themes\/THEME\/gtk-VERSION\/gtk.css@ and
-- @DATADIR\/share\/themes\/THEME\/gtk-VERSION\/gtk.css@, where @THEME@ is the name of
-- the current theme (see the t'GI.Gtk.Objects.Settings.Settings':@/gtk-theme-name/@ setting), @DATADIR@
-- is the prefix configured when GTK+ was compiled (unless overridden by the
-- @GTK_DATA_PREFIX@ environment variable), and @VERSION@ is the GTK+ version number.
-- If no file is found for the current version, GTK+ tries older versions all the
-- way back to 3.0.
-- 
-- In the same way, GTK+ tries to load a gtk-keys.css file for the current
-- key theme, as defined by t'GI.Gtk.Objects.Settings.Settings':@/gtk-key-theme-name/@.
