scss代码:

/*一般mixin*/

@mixin helloMixin {
    display: inline-block;
    padding: 20px;
    font: {
        size: 20px;
        weight: 500;
    }

    color: red;
}

/*嵌套mixin*/

@mixin helloMixin2 {
    padding: 10px;

    @include helloMixin;

    background-color: red;
}

/*参数mixin*/

@mixin sexy-border($color, $width) {
    border: {
        color: $color;
        width: $width;
        style:dashed;
    };
}
.div {
    width: 100px;
    @include helloMixin2;
}

.div {
    @include sexy-border(blue,2px);
}

编译后得到的css代码:

@charset "UTF-8";
/*一般mixin*/
/*嵌套mixin*/
/*参数mixin*/
.div {
  width: 100px;
  padding: 10px;
  display: inline-block;
  padding: 20px;
  font-size: 20px;
  font-weight: 500;
  color: red;
  background-color: red;
}

.div {
  border-color: blue;
  border-width: 2px;
  border-style: dashed;
}
