Preserving CSS Text Rendering During Transitions in WebKit

CSS transitions are commonly used to smoothly change the appearance of elements, such as when transitioning between transformed states. However, in WebKit-based browsers, text rendering may undergo subtle changes during these transitions.

One way to address this is by employing the -webkit-font-smoothing: antialiased property-value pair on the affected text. However, this approach may not always be desirable, as it can alter the overall rendering appearance.

A more comprehensive solution is to force hardware acceleration on the parent element of the transitioning text using the -webkit-transform: translateZ(0px) property. This technique effectively bypasses WebKit's rendering quirks during transitions, preserving the default text rendering behavior.

It's important to note that this hack disables font smoothing, potentially compromising text quality. Careful consideration should be given to the trade-offs before implementing this solution.
