CSS 转换和过渡在 Safari 中不起作用

Question

我正在研究 <nav>对于移动网站。它在 Firefox 和 Chrome 中有效，但在 Safari 中无效。我在 Windows 8.1 上运行它，我在 iPad mini 的 Safari 上观察到同样的问题。

在下面的代码片段中，如果您查看移动 View (max-width: 768px) 并单击右上角的菜单图标，该图标应该会变成十字 (X) 图标以及导航菜单应该会滑下来。

$("a.nav-opener").click(function(e) {
  e.preventDefault();
  $('body').toggleClass("nav-active");
});

@media screen and (max-width: 768px){

  .holder {
    padding: 14px;
  }

  .logo {
    float: none;
    display: block;
    margin: 0px auto;
    width: 168px;
    position: relative;
    z-index: 2;
  }

  a {
    text-decoration: none;
    color: #DC7952;
    outline: medium none;
  }

  .logo img {
    width: 100%;
    height: auto;
    display: block;
  }

  img {
    max-width: 100%;
    height: auto;
  }

  .nav-opener {
    display: block;
    position: absolute;
    top: 0px;
    right: 0px;
    border-left: 1px solid #D4D4D4;
    width: 65px;
    height: 53px;
    text-indent: -9999px;
    overflow: hidden;
    background: none repeat scroll 0% 0% transparent;
    z-index: 15;
  }

  .nav-opener::before, .nav-opener::after {
    content: "";

  .nav-opener::before, .nav-opener::after, .nav-opener span {

转换和过渡在没有浏览器前缀的 safari 和 chrome 上不起作用，这是用于 safari 的 webkit 所以使用:

-webkit-transform 和 -webkit-transition 代替...
