在CSS中获取属性的值 [英] Get value of attribute in CSS

问题描述

我有这个HTML代码：

I have this HTML code:

<div data-width="70"></div>

我想设置CSS的宽度等于data-width属性的值，例如。类似这样：

I want to set it's width in CSS equal to the value of data-width attribute, e.g. something like this:

div {
    width: [data-width];
}

我看到这是在某个地方完成的，但我不记得了。非常感谢。

I saw this was done somewhere, but I can't remember it. Thanks.

推荐答案

好吧，伙计们，这是我要找的：

Okay, guys, this is what I was looking for:

问题是即使某些主流浏览器（在这种情况下是Chrome）也不支持它。

The problem is that it's not supported even by some of the major browsers, in this case Chrome.
