【问题描述】：

为什么transform:rotateY(); 会导致 div 仅在 Safari 中重叠？这里有一些屏幕截图可以更好地解释......

它应该是什么样子：

它不应该是什么样子（仅在 Safari 中出现）：

这是一个非常奇怪的行为，我已经从整个代码中删除了transform:rotateY();，但它引发了关于为什么会发生这种情况的有效混淆。

这里是原程序的一段代码sn-p：

window.addEventListener('load', function() 
  var percentHeight = Math.floor(window.innerHeight / 100);
  var percentWidth = Math.floor(window.innerWidth / 100);
  initializeMessages();
  var hourHand = document.getElementById('watchHourHand');
  var minuteHand = document.getElementById('watchMinuteHand');
  var secondHand = document.getElementById('watchSecondHand');
  var markers = document.getElementById('markers');
  for (var i = 0; i != 12; i++) 
    var marker = document.createElement('div');
    marker.className = 'marker';
    markers.appendChild(marker);
    markers.appendChild(marker);
  
  window.setInterval(function() 
    //minute degrees = 6
    //second degrees = 6
    //hour degrees = 30
    var date = new Date();
    var hours = date.getHours();
    if (hours > 12) 
      hours = hours - 12;
    
    if (hours == 0) 
      hours = 12;
    
    var minutes = date.getMinutes();
    var seconds = date.getSeconds();
    var secondDegrees = seconds * 6;
    var minuteDegrees = minutes * 6 + seconds / 60;
    var hourDegrees = hours * 30 + minutes / 60;
    if (hourDegrees == 0) 
      //hourHand.className = 'noTransition';
      hourDegrees = 360;
    
    hourHand.style.oTransform = 'rotate(' + hourDegrees + 'deg)';
    hourHand.style.mozTransform = 'rotate(' + hourDegrees + 'deg)';
    hourHand.style.webkitTransform = 'rotate(' + hourDegrees + 'deg)';
    hourHand.style.msTransform = 'rotate(' + hourDegrees + 'deg)';

Safari 用户，请仔细查看#watchBelt 样式（查看sn-p 中CSS 代码块的顶部以获取也与#watchBelt 相关的代码）。这是#watchBelt 代码：

#watchBelt 
      width: 50%;
      margin: auto;
      height: 100%;
      background: #555;
      border-radius: 50px;
      box-shadow: 0px -10px 3px #444;
      transform: rotateY(20deg);
    

我没有在 IE 或 Edge 中对此进行过测试，如果有人能告诉我在 IE 和/或 Edge 中发生了什么，我将不胜感激。谢谢你:)

【问题讨论】：

您找到解决此错误的方法了吗？

【参考方案1】：

在 Safari 中，z 值似乎与确定哪个对象在前面渲染有关。确保要在前景中渲染的对象具有更高的 z 值应该可以解决问题：

.yourForegroundClass 
   /* Your Style */
   transform: translateZ(999999px);

这显然不是最干净的解决方案。

【参考方案2】：

#watchBelt 
      width: 50%;
      margin: auto;
      height: 100%;
      background: #555;
      border-radius: 50px;
      box-shadow: 0px -10px 3px #444;
      transform: rotateY(20deg);
position :relative;
z-index:-1;/*decrease it until it moves to back*/
    

【讨论】：

欢迎来到 Stack Overflow！虽然此代码可能会回答问题，但提供有关此代码为何和/或如何回答问题的额外上下文可提高其长期价值。

对不起，这不起作用 :) 谢谢你的回答，欢迎来到 *** :)

这里重要的一点是“position:relative;”

也许这对某人有帮助：将“perspective: 1000px”添加到包装层，在这里找到它：***.com/questions/22621544/…
