Activating hardware acceleration: utilizing translate3d

In a recent discussion by David Walsh, he mentions the potential for hardware acceleration through the use of the translate3d property in CSS.

Here's how it operates:

.animClass {
    -webkit-transform: translate3d(0, 0, 0);
    -webkit-backface-visibility: hidden;
    -webkit-perspective: 1000;

    /* additional animation properties can be included here */
}

I am currently debating whether or not to implement this technique. My website has numerous transitions, although they do not occur simultaneously. I aim to provide a seamless experience across all devices, including older models and high-performance ones.

Therefore, my inquiries are as follows:

  1. Does utilizing the above technique enhance the performance of transitions like opacity, width, and positioning? And should the mentioned properties be incorporated?
  2. How universally compatible is this approach? While IE8 and earlier versions are not a concern, I am particularly interested in its effectiveness on mobile platforms such as Android, iOS, and Windows Phone. What adjustments need to be made for broader compatibility?
  3. Is it necessary to apply the hardware-enabling code to every element with a transition property? If so, can it be simplified into a SASS mixin for easier implementation?

Answer №1

Here's a clue for the third part:

Remember that browsers are already optimized to handle layouts and design animations efficiently. Adding hardware acceleration to every animated element can actually hinder performance by negating these optimizations. It's important to use proper tools to assess your website's rendering performance before resorting to any shortcuts like this.

In summary: browsers continually improve with each update, and it's unlikely that an individual can outsmart the collective effort of developers who dedicate years to refining rendering engines.

Answer №2

  • In my experience, employing hardware acceleration can greatly enhance the speed and performance of web views on Android and iOS if used judiciously. However, overusing it on all elements may actually hinder performance, especially on devices with limited memory.

Personally, I find it beneficial for rendering high-quality images without blurriness and ensuring that the entire image is cached. Beware though, excessive use of hardware acceleration on multiple elements in an Android application can lead to crashes. Similar cautions apply to iOS as well, despite its superior performance in web views.

  • Hardware acceleration is compatible across browsers but requires prefixing. On Android, I implement it as far back as version 4.2.

  • To optimize performance, assign hardware acceleration to specific elements by utilizing a designated class. Remove the class when no longer necessary.

Only utilize hardware acceleration when essential, and limit its application to specific elements at any given time. Be cautious of applying it to numerous elements simultaneously, as the threshold varies depending on the device's memory constraints.

Avoid animating with position; instead, opt for translate to enhance animation performance, particularly on mobile devices.

I refrain from disabling hardware acceleration in my applications as it would significantly diminish their performance :)
