-webkit-transition

Deprecated
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard
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.

The -webkit-transition Boolean CSS media feature is a Chrome extension whose value is true if the browsing context supports CSS transitions. It was never supported in browsers not based on WebKit or Blink.

Note: You should not use this media feature; it was never specified, has never been widely implemented, and has been removed from all browsers. Use an @supports feature query instead.

Examples

Use @supports instead

Do not use the -webkit-transition media feature. Instead, test for transition support using the CSS @supports at-rule, like this:

@supports (transition: initial) {
  /* CSS to use if transitions are supported */
}

Obsolete example

Before this became obsolete, you could use -webkit-transition in your CSS like this:

@media (-webkit-transition) {
  /* CSS to use if transitions are supported */
}

Specifications

Not part of any specification. Apple has a description in Safari CSS Reference; this is now called simply transition there.
