CSS性能问题 [英] CSS Performance issues

问题描述

样式表（CSS）的哪些方面可能导致网站性能低下？

解决方案

CSS？不是那么多，它是相当紧张，但在旧的（像第4代）浏览器，我看到的问题：

• * 选择器


• 使用继承很多


• 加载大量外部资源（图片，其他CSS文档）


• 应用大量的内容您可以调用 div div

之类的非锚定选择器基本上，级联或级联很多。

What are the aspects of style sheets (CSS) that can lead to poor performance of web sites? Anything that can really choke up the CPU?

thanks in advance.

解决方案

CSS? Not so much it's pretty tight, but on older (like gen 4) browsers I've seen problems with:

• doing too much on the * selector
• using inherit a lot
• using the IE expression value abusively
• loading a lot of external resources (images, other CSS docs)
• applying a lot of what you might call unanchored selectors like div div

Basically anything which would be difficult to cascade through or would cascade a lot.
