Notes

Though present in early (2002) drafts of CSS3 Fonts, font-smooth has been removed from this specification and is currently not on the standard track.

  1. WebKit implements something similar with a different name -webkit-font-smoothing and different values: none, antialiased and subpixel-antialiased.

  2. Firefox implements something similar with a different name -moz-osx-font-smoothing and different values: auto, inherit, unset, grayscale.

  3. Works only on Mac OS X platform.

* Partial support with prefix.

Bugs

  • Chrome briefly removed and then re-instated support for -webkit-font-smoothing in 2012.
