问题描述
我有这些 div,我用 .tocolor
设置样式,但我还需要唯一标识符 1、2、3、4 等,所以我将其添加为另一个类 .
I have these divs that I'm styling with .tocolor
, but I also need the unique identifier 1,2,3,4 etc. so I'm adding that it as another class tocolor-1
.
<div class="tocolor tocolor-1"> tocolor 1 </div>
<div class="tocolor tocolor-2"> tocolor 2 </div>
<div class="tocolor tocolor-3"> tocolor 3 </div>
<div class="tocolor tocolor-4"> tocolor 4 </div>
.tocolor{
background: red;
}
有没有办法只使用 1 个类 tocolor-*
.我尝试在这个 css 中使用通配符 *
,但它不起作用.
Is there a way to have just 1 class tocolor-*
. I tried using a wildcard *
as in this css, but it didn't work.
.tocolor-*{
background: red;
}
推荐答案
你需要的是属性选择器.使用您的 html 结构的示例如下:
What you need is called attribute selector. An example, using your html structure, is the following:
div[class^="tocolor-"], div[class*=" tocolor-"] {
color:red
}
在 div
的地方你可以添加任何元素,也可以完全删除它,在 class
的地方你可以添加指定元素的任何属性.
In the place of div
you can add any element or remove it altogether, and in the place of class
you can add any attribute of the specified element.
[class^="tocolor-"]
— 以tocolor-"开头.[class*=" tocolor-"]
— 包含直接出现在空格字符之后的子字符串tocolor-".
[class^="tocolor-"]
— starts with "tocolor-".[class*=" tocolor-"]
— contains the substring "tocolor-" occurring directly after a space character.
