-webkit-transform-3d

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2016.

The -webkit-transform-3d Boolean CSS media feature is a WebKit extension whose value is true if vendor-prefixed CSS 3D transforms are supported.

Note: While this media feature is currently supported by most browsers. If possible, use an @supports feature query instead.

-webkit-transform-3d is a Boolean CSS media feature whose value is true if the browser supports -webkit prefixed CSS 3D transforms.

true: The browser supports the 3D CSS transforms with the -webkit prefix and supports non-standard, prefixed media queries.
false: The 3D CSS transforms prefixed with -webkit are not supported by the browser.

css

@media (-webkit-transform-3d) {
  .foo {
    transform-style: preserve-3d;
  }
}

A better method for checking for browser support is using a feature query:

css

@supports (transform-style) {
  .foo {
    transform-style: preserve-3d;
  }
}
