This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Note: Since Firefox 58, this media feature is no longer available to web content — it is only available internally (e.g. to XUL / chrome code). See bug 1396066 for more details.

The -moz-mac-graphite-theme Gecko-only CSS media feature can be used to apply styles based on whether the user has the Mac OS X "Graphite" theme enabled.


If the user has configured their device to use the "Graphite" appearance on Mac OS X, this is 1. If the user is using the standard blue appearance, or is not on Mac OS X, this is 0.

Media: media/visual
Accepts min/max prefixes: no
