链接是指HTML锚点元素，由<a>标签表示。这个元素用于创建超链接，允许用户在网页和其他资源之间导航。
CSS (Cascading Style Sheets), is a powerful language used to control the visual presentation of web pages. One of the most important things we can do with CSS is changing the color of links on the webpage. In this article, we will cover different ways to change the color of links in CSS.
通过使用 "a" 选择器
This is the basic way to change the color of links in CSS. This selector targets all links on a webpage. The color property is used to change the color of the text of the link. Here is an example −
a{
color:blue;
}

By using "id" and "class" selector
如果我们想要改变特定链接的颜色，我们可以使用类选择器或ID选择器。例如，如果我们在某些链接上有一个名为"special-link"的类，我们将使用以下代码来改变这些链接的颜色 −
.special-link{
color:blue; (By using class seletor)
}
#special-link{
color:blue; (By using id seletor)
}

通过使用“:hover”伪类
To change the color of a link when it is hovered over, we use the ":hover" pseudo-class. For example
a:hover {
color: red;
}
当鼠标悬停在链接上时，此CSS将更改链接的颜色为红色。
