Webkit-Based Text Distortion Post-Animation with Translate3d: A Persistent Issue
The issue of blurry or distorted text after animating elements using Webkit-based browsers has plagued developers for an extended period. This issue affects browsers like Safari and the iPhone's default browser.
Background:
JavaScript-based sliders often utilize the -webkit-transform: translate3d property for smooth animation. However, this technique inadvertently causes text within the animated element to become blurry.
Failed Attempts at Resolution:
Various workarounds have been attempted to resolve this issue, including:
- Removing relative positioning
- Adding -webkit-font-smoothing: antialiased
However, these measures have proven ineffective.
Solution:
Despite exploring various options, the only solution that consistently eliminates text blurring is to revert to JavaScript-based animation, bypassing translate3d altogether. However, this compromise sacrifices performance on WebKit-enabled devices.
A Partial Solution:
While a comprehensive solution remains elusive, a partial remedy has been discovered that mitigates the distortion somewhat:
top: 49.9%; left: 49.9%; -webkit-transform: translate(-50.1%, -50.1%); transform: translate(-50.1%, -50.1%);
This technique introduces a slight offset of 0.1% to the element's position and transform. While it does not fully eliminate the blur, it significantly reduces its impact.

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
