如何检查CSS3是否启用了硬件加速？

Question

我有以下css。

-webkit-transform: translate3d(0,0,0);
-moz-transform: translate3d(0,0,0);
-ms-transform: translate3d(0,0,0);
-o-transform: translate3d(0,0,0);
transform: translate3d(0,0,0);

-webkit-transition: height 450ms cubic-bezier(0.840, 0.005, 0.755, 0.995);
-moz-transition: height 450ms cubic-bezier(0.840, 0.005, 0.755, 0.995); 
-ms-transition: height 450ms cubic-bezier(0.840, 0.005, 0.755, 0.995); 
-o-transition: height 450ms cubic-bezier(0.840, 0.005, 0.755, 0.995); 
transition: height 450ms cubic-bezier(0.840, 0.005, 0.755, 0.995);

我了解到 translate3d 启用了硬件加速，但我该如何检查呢？我的眼睛无法区分它们。
