Scss混合宏可以传多个参数

@mixin center($width,$height){
  width: $width;
  height: $height;
  position: absolute;
  top: 50%;
  left: 50%;
  margin-top: -($height) / 2;
  margin-left: -($width) / 2;
}

传值

.box-center {
  @include center(500px,300px);
}

编译

.box-center {
  width: 500px;
  height: 300px;
  position: absolute;
  top: 50%;
  left: 50%;
  margin-top: -150px;
  margin-left: -250px;
}

特别的参数“…”

可以使用参数来替代

@mixin box-shadow($shadows...){
  @if length($shadows) >= 1 {
    -webkit-box-shadow: $shadows;
    box-shadow: $shadows;
  } @else {
    $shadows: 0 0 2px rgba(#000,.25);
    -webkit-box-shadow: $shadow;
    box-shadow: $shadow;
  }
}

调用:

.box {
  @include box-shadow(0 0 1px rgba(#000,.5),0 0 2px rgba(#000,.2));
}

编译:

.box {
  -webkit-box-shadow: 0 0 1px rgba(0, 0, 0, 0.5), 0 0 2px rgba(0, 0, 0, 0.2);
  box-shadow: 0 0 1px rgba(0, 0, 0, 0.5), 0 0 2px rgba(0, 0, 0, 0.2);
}
