-webkit-transform-3d

-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.

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

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

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