http://lesscss.cn/ 上编写了一些函数

.radius(leftTop, @w: 30px){
    border-top-left-radius: @w;
}

.radius(rightTop, @w: 30px){
  border-top-right-radius: @w;
}

.radius(leftBottom, @w: 30px){
  border-bottom-left-radius: @w;
}

.radius(rightBottom, @w: 30px){
  border-bottom-right-radius: @w;
}

.radius(@w: 30px){
  border-radius: @w;
}


div{
   200px;
  height: 200px;
  margin: 20px;
}

// .box1{
