<style>
/*混合名称的核心是:是定义一个名称,名称里面是双方都具备的代码
注意一下:如果加括号代码
*/

带参数的混合：
代码语言：javascript复制<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
/*.whc(@w,@h,@c)
{
width: @w;
height: @h;
background: @c;
}
.whc(@w:100px,@h:100px,@c:pink)
{
width: @w;
height: @h;
background: @c;
}
.box1
{
/*.whc(200px,200px,red);*/
/*.whc(@c:red);
}
.box2
{
.whc(200px,200px,blue);
}*/
/*编译后的*/
.box1 {
/*.whc(200px,200px,red);*/
width: 100px;
height: 100px;
background: red;
}
.box2 {
width: 200px;
height: 200px;
background: blue;
}
</style>
</head>
<body>
<div class="box1"></div>
<div class="box2"></div>
</body>
</html>
记住，如果要·指定的话，名称加上值就行了
代码语言：javascript复制.whc(@c:red);
