css作业-立方体旋转

咦,发现两个新知识.

1. perspective 隔代也会有影响. 所以可以放在爷爷身上.能解决旋转容器时, perspective-origin 跟着转.
   2.scss确实厉害, 本来css是无法用一些数学函数的. 但scss有啊!这个还是挺方便的.

html

        <div class="wrapper">
           <div class="content">
             <div class="item">1</div>
             <div class="item">2</div>
             <div class="item">3</div>
             <div class="item">4</div>
             <div class="item">5</div>
             <div class="item">6</div>
           </div>
         </div>

scss
