Why Does Translate3d Cause Blurry Text in WebKit-Based Browsers?

Webkit-Based Blurry Text Issue in Animated Elements Using translate3d

A common problem encountered across WebKit-based browsers, including the iPhone, is distorted and blurry text after implementing translate3d for animations. This can be particularly prevalent when using -webkit-transform: translate3d as the animation method.

One potential solution suggested in forums involved removing relative positioning and adding a -webkit-font-smoothing: antialiased rule. However, these adjustments often prove ineffective.

Dirty Solution

As a potential workaround, while not an elegant or optimal one, adjusting the positioning by adding a fraction to the transform values has been reported to mitigate the issue:

top: 49.9%;
left: 49.9%;
-webkit-transform: translate(-50.1%, -50.1%);
transform: translate(-50.1%, -50.1%);

This technique relies on slightly offsetting the transform with a fraction, which seems to prevent the blurring effect associated with translate3d animations in WebKit browsers.

Other Considerations:

Alternative approaches may include:

• Utilizing JavaScript-based animations instead of translate3d.
• Investigating the underlying cause of the text distortion within the specific implementation and addressing it directly.
