Why Are My CSS Transitions Making Images Blurry in Chrome?
Dec 23, 2024 am 06:09 AMCSS Transition Effect Causing Blurry Images or Movement in Chrome
Problem:
When applying a CSS transition effect that involves moving a division, Chrome exhibits undesirable behavior such as making the image in the division blurry or displacing it slightly. This issue persists only when the page has scrollbars.
Solution:
To prevent these effects, implement the following CSS changes:
.your-class-name { /* ... */ -webkit-backface-visibility: hidden; -webkit-transform: translateZ(0) scale(1, 1); }
Explanation:
- -webkit-backface-visibility: hidden: Disables rendering of the division's backface, which is unnecessary for simple translations and transformations.
- -webkit-transform: translateZ(0) scale(1, 1); Sets the division's Z-axis translation to zero and scales it back to its original size, ensuring the image remains in place.
2020 Update:
- For blurry images, consider using the image-rendering CSS property as suggested in other answers.
- For accessibility and SEO, consider replacing background images with img tags and using the object-fit CSS property.

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.

In CSS, selector and attribute names are case-sensitive, while values, named colors, URLs, and custom attributes are case-sensitive. 1. The selector and attribute names are case-insensitive, such as background-color and background-Color are the same. 2. The hexadecimal color in the value is case-sensitive, but the named color is case-sensitive, such as red and Red is invalid. 3. URLs are case sensitive and may cause file loading problems. 4. Custom properties (variables) are case sensitive, and you need to pay attention to the consistency of case when using them.
