Do you know that we are able to hardware-accelerate graphics-intensive CSS options by offloading them to the GPU (Graphics Processing Unit) for higher rendering efficiency within the browser?

Computer systems have graphics playing cards appropriate for CSS {hardware} acceleration. Due to this, we are able to leverage GPU energy for these heavier options in order that our websites and purposes can carry out sooner than is feasible in browsers operating on the CPU.

On this article, we’ll cowl the usage of CSS {hardware} acceleration on desktop and cellular browsers.

CSS {Hardware} Acceleration on Desktop and Cellular Browsers

Ever puzzled how some CSS animations run so easily within the browser?

CSS animations, transforms and transitions are usually not routinely GPU accelerated, and as a substitute execute from the browser’s slower software program rendering engine.

So what precisely forces the browser to swap to GPU mode? Many browsers present GPU-accelerated rendering utilizing sure CSS guidelines.

Presently, browsers like Chrome, FireFox, Edge, and Safari all ship with {hardware} acceleration. With CSS, the strongest indication of acceleration is {that a} 3D transformation is being utilized to a component.

For instance:

.dice {
   -webkit-transform: translate3d(250px,250px,250px)
   rotate3d(250px,250px,250px,-120deg)
   scale3d(0.5, 0.5, 0.5);
}

In some instances, you may not need a 3D transformation on the aspect, however nonetheless want to benefit from GPU acceleration. That’s when a number of easy CSS properties come in useful that trick the browser into triggering GPU-accelerated rendering.

Although we’re not animating a component in 3D area, we are able to allow 3D rendering. On the very least, the rework: translateZ(0); declaration triggers GPU acceleration in fashionable desktop and cellular browsers.

This appears to be the simplest approach of triggering GPU acceleration (all vendor prefixes included):

.dice {
   -webkit-transform: translateZ(0);
   -moz-transform: translateZ(0);
   -ms-transform: translateZ(0);
   -o-transform: translateZ(0);
   rework: translateZ(0);
   /* Different rework properties right here */
}

In Chrome and Safari we would see a flickering impact when utilizing CSS transforms or animations. The next declarations can be utilized to repair the difficulty:

.dice {
   -webkit-backface-visibility: hidden;
   -moz-backface-visibility: hidden;
   -ms-backface-visibility: hidden;
   backface-visibility: hidden;

   -webkit-perspective: 1000;
   -moz-perspective: 1000;
   -ms-perspective: 1000;
   perspective: 1000;
   /* Different rework properties right here */
}

One other methodology that appears to work effectively in WebKit-powered desktop and cellular browsers is translate3d:

.dice {
   -webkit-transform: translate3d(0, 0, 0);
   -moz-transform: translate3d(0, 0, 0);
   -ms-transform: translate3d(0, 0, 0);
   rework: translate3d(0, 0, 0);
  /* Different rework properties right here */
}

Native cellular purposes additionally make good use of the gadget GPU –– that’s why they’re identified to carry out barely higher than Internet apps. Utilizing CSS {hardware} acceleration may be particularly helpful on cellular gadgets as a result of it helps cut back useful resource consumption on the gadget.

GPU-Accelerated Rendering in CSS: Remaining Ideas

The strategies we coated ought to solely be used on the weather we’re animating. They could enhance efficiency on 2D transforms, nevertheless it’s not sensible to make use of them on every thing only for the sake of {hardware} acceleration.

Watch out with every of those strategies and solely use them if you happen to expertise a real efficiency win. Utilizing the GPU unnecessarily could cause vital efficiency points as a result of it will increase reminiscence use –– it can additionally have an effect on the battery life on cellular gadgets.
