CSS3 navigation menu, when your motion layer is below the display layer, the transition will cause the page to flicker. The reason is a bug generated by Chrome when it initially renders the CSS animation. Although this problem cannot be verified for the time being. The root cause, but there are currently two known solutions:

-webkit-backface-visibility: hidden; (Set whether the back side of the converted element is visible when facing the user: hidden)

-webkit-transform-style: preserve-3d; (Set how embedded elements are rendered in 3D space: preserve 3D).

The specific code is as follows:

<head>
<title>css3的属性transition制作菜单导航</title>
<style>
*{margin:0px;padding:0px;}
body{background:#45B5DA;margin:0px;padding:0px;}
.tips{width:370px;margin:0 auto;line-height:24px;padding-top:10px;}
.bredcolor{color:#fff;}
#nav{position:absolute;top:50%;left:50%;margin-top:-20px;margin-left:-185px;}

  当你运动层在显示层下面时，transition会使页面产生闪动，原因是Chrome在初始渲染CSS动画时产生的Bug，虽然暂时无法考证这个问题的根本原因，但是目前已知的解决方案有两条：
  -webkit-backface-visibility: hidden;（设置进行转换的元素的背面在面对用户时是否可见：隐藏）
  -webkit-transform-style: preserve-3d; （设置内嵌的元素在 3D 空间如何呈现：保留 3D ）
