What does -webkit-transform: translate3d(0,0,0); exactly do? Apply to body?

Why does it invoke the GPU?

Although the translate3d(0,0,0) does not visually move the element, it instructs the browser to use 3D rendering. This action optimizes the performance by employing the GPU-accelerated compositing layer.

Reminder: Stacking context and layout

Activating this feature affects the stacking contexts of elements and may unintentionally interfere with z-index. Be sure to double-check your layout changes when using this heavyweight technique.

Trying alternative translations & flicker prevention

translateZ(0) mirrors the effects of translate3d(0,0,0), providing an alternative method of triggering hardware acceleration. To prevent the dreaded flicker on Chrome and Safari, couple it with:

 /* No one likes flickers, not even light bulbs */
.smooth-animation {
  -webkit-backface-visibility: hidden;
  -webkit-perspective: 1000;
}

Mobile migration: Making the swipe smoother

For smartphones and MobileSafari in particular, scroll-induced artifacting can occur. Apply translate3d(0,0,0) to scroll bar container children to create a more visually pleasing and smooth scrolling experience.

Striking the balance: Performance vs Memory usage

Before applying translate3d(0,0,0) universally to your website, consider the performance implications. While it might boost interactivity, overuse may lead to memory bloat. Analyze and determine if individual page elements need GPU acceleration.

Visual Impact of transformations

3D transforms use matrix mapping to distribute elements onto the frame buffer. When using these transformations, keep in mind that non-3D CSS alterations such as color or border adjustments may render with a lower priority.

Consequence management: Overlays and z-index quirks

Applying translate3d(0,0,0) can create unexpected results, especially with overlays. If elements have unique z-index values, the visual impact may differ from your original intentions.

Pitfalls and Practices: Keeping performance maxed

While translate3d(0,0,0) can supercharge your webpage, overuse can actually decrease performance, especially on less powerful devices. Using browser profiling tools can help you mitigate memory usage and stay ahead in the web race.

Leverage browser profiling tools

Chrome's DevTools can help you to ascertain the layers at which your elements are painting and compositing. Be sure to validate that you're using the GPU juice where it's really needed.

Watch when it's worth it

Lastly, this may not be a one-size-fits-all solution. Simple elements may not benefit as much. Evaluate your elements individually to see if the performance boosts justify the resource use.
