CSS不能选择带有数字的类/ID吗? [英] CSS can't select classes/id's with numbers in it?

问题描述

为什么您不能在CSS中使用数字，还有另一种方式来完成这项工作?我有以下代码:

Why can't you use numbers in CSS and is there another way of doing the job? I have the following code:

<div class="center 400-width" id="position">
    <div class="" id="header">
        Header
    </div>
    <div class="" id="content">
        Content
    </div>
    <div class="" id="footer">
        Footer
    </div>
</div>

CSS选择类 400-width ，这表示容器的宽度为 400px . background-color 用于检查其是否正确.

The CSS selects the class 400-width which means the container gets a width of 400px. And the background-color is for checking if it's true.

.400-width{
    width:400px;
    background-color:blue;
    color:white;
}

这不会立即发生，因为您可以在此处

It doesn't happen right now as you can see here

我通过用 400 替换 400-来解决了这个问题.这样就变成了 fourwidth .

I solved the problem by replacing 400- by four. So it becomes fourwidth.

推荐答案

我也遇到了同样的问题....实际上这不是问题..

i have faced the same problem.... actually it not a problem anyway..

而不是'.400-width'使用'.width-400'

instead of '.400-width' use '.width-400'
