用 CSS 确定元素在不面向屏幕时是否可见

To determine whether an element is visible when not facing the screen, use the backface-visibility attribute:

Example

Live Demonstration

<!DOCTYPE html>
<html>
<head>
   <style>
      .demo1 {
         position: relative;
         width: 150px;
         height: 150px;
         background-color: yellow;
         perspective: 80px;
         margin: 50px;
         perspective-origin: left;
         transform: rotateY(180deg);
      }
      .demo2 {
         position: absolute;
         padding: 20px;
         background-color: orange;
         transform-style: preserve-3d;
         transform: rotateX(45deg);
         backface-visibility: visible;
      }
      </style>
   </head>
   <body>
      <h1>Rotation</h1>
      <div class = "demo1">Demo
         <div class = "demo2">Demo</div>
      </div>
   </body>
</html>
