[英]Using pseudo class selectors to change content?
How can I change the text which is contained in <p>
tags by using CSS's pseudo class selectors? 如何使用CSS的伪类选择器更改
<p>
标记中包含的文本?
For example, when I hover over a paragraph, the content of paragraph must change to what would be specified in p:hover
selector. 例如,当我将鼠标悬停在一个段落上时,该段落的内容必须更改为
p:hover
选择器中指定的内容。
One way is to use p:hover:before
along with the content
attribute. 一种方法是将
p:hover:before
与content
属性一起使用。
Here's an example: 这是一个例子:
Html: HTML:
<p>
<span>First text!</span>
</p>
CSS: CSS:
p:hover span {
display:none
}
p:hover:before {
content:"Second text appears instead!";
color:red;
}

property, check out this nice little article . 如果您想了解更多关于

属性的信息,请查看这篇不错的小文章 。

display: none;
}
p .normalDisplay {
display: inline;
