gtk:css-provider-prefers-contrast (object)

object -- a gtk:css-provider object
mode -- a gtk:instance-contrast value

The accessor for the prefers-contrast slot of the gtk:css-provider class gets or sets the contrast mode to use for the user interface.

When set to :more or :less, the UI is rendered in high or low contrast. When set to :no-preference (the default), the user interface will be rendered in default mode.

This setting is be available for media queries in CSS:

@media (prefers-contrast: more) {
  // some style with high contrast
}  

Changing this setting will reload the style sheet.
