Applications based on WebKit or Blink, such as Safari and Chrome, support a number of special WebKit extensions to CSS. These extensions are generally prefixed with -webkit. All -webkit prefixed properties also work with an -apple prefix. A few are prefixed with -epub.

WebKit-only properties (avoid using on websites)

Note: These properties will only work in WebKit applications, and are not on a standards track.



C – G

H – I



N – O


R – S
