问题描述

为什么 transform:rotateY(); 导致div仅在Safari中重叠?这是一些屏幕截图，可以更好地说明...

Why does transform:rotateY(); cause a div to overlap in Safari only? Here are some screen shots to better explain...

它应该是什么样的

What it should look like:

它不应该是什么样子(仅发生在Safari中):

What it shouldn't look like (only occurs in Safari):

这是一个非常奇怪的行为，此后我从整个代码中删除了 transform:rotateY(); ，但它引起了人们对为什么发生这种情况的困惑.

This is very strange behavior, I have since removed the transform:rotateY(); from the entire code but it brings up valid confusion about why this is happening.

这是原始程序的代码段:

Here is a code snippet of the original program:

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)';

Safari用户，请仔细查看#watchBelt样式(请查看代码段中CSS代码块的顶部，以获取与#watchBelt相关的代码).这是#watchBelt代码:

Safari users, look closely at the #watchBelt styles (look at the top of the CSS code block in the snippet for code that is also relevant to #watchBelt). Here is the #watchBelt code:

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

我还没有在IE或Edge中进行过测试，所以我很感激任何可以告诉我IE和/或Edge中发生了什么的人.谢谢:)

I have not tested this in IE or Edge and I would be appreciative of anyone who could tell me what happens in IE and/or Edge. Thank you :)

推荐答案

在Safari中，z值似乎与确定哪个对象在内部呈现有关.确保要在前景中渲染的对象具有较高的z值，可以解决此问题:

In Safari the z-value seems to be involved in determining which object gets rendered infront. Making sure the object you want rendered in foreground has a higher z-value should solve the problem:

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

这显然不是最干净的解决方案.

This is obviously not the cleanest solution.
