这个解决方案似乎适用于包括IE6+在内的所有浏览器，使用scale(-1,1)(适当的镜像)和适当的filter/-ms-filter属性(IE6-8):

/* Cross-browser mirroring of content. Note that CSS pre-processors
  like Less cough on the media hack. 

  Microsoft recommends using BasicImage as a more efficent/faster form of
  mirroring, instead of FlipH or some kind of Matrix scaling/transform.

*/

/* IE8 only via hack: necessary because IE9+ will also interpret -ms-filter,
  and mirroring something that's already mirrored results in no net change! */
@media \0screen {
  .mirror {
    -ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(mirror=1)";
  }
}
.mirror {
  /* IE6 and 7 via hack */
  *filter: progid:DXImageTransform.Microsoft.BasicImage(mirror=1);
  /* Standards browsers, including IE9+ */
  -moz-transform: scale(-1,1);
  -ms-transform: scale(-1,1);
  -o-transform: scale(-1,1); /* Op 11.5 only */
  -webkit-transform: scale(-1,1);
  transform: scale(-1,1);
}

还有一个真正镜像的rotateY:

transform: rotateY(180deg);

这一点或许更清楚，也更容易理解。

编辑:似乎在Opera上不起作用……遗憾的是。但它在Firefox上运行良好。我猜这可能需要隐含地说我们正在做某种翻译3d ?或者类似的东西。

为了跨浏览器兼容，创建这个类

.mirror-icon:before {
    -webkit-transform: scale(-1, 1);
    -moz-transform: scale(-1, 1);
    -ms-transform: scale(-1, 1);
    -o-transform: scale(-1, 1);
    transform: scale(-1, 1);
}

并将其添加到您的图标类，即。

<i class="icon-search mirror-icon"></i>

以获得左侧有手柄的搜索图标

-moz-transform: scale(-1, 1);
-webkit-transform: scale(-1, 1);
-o-transform: scale(-1, 1);
-ms-transform: scale(-1, 1);
transform: scale(-1, 1);

这两个参数是X轴和Y轴，-1将是一个镜像，但您可以根据需要缩放到任何大小。上下颠倒就是(-1，-1)

你可以使用

.your-class{ 
      position:absolute; 
      -moz-transform: scaleX(-1); 
      -o-transform: scaleX(-1); 
      -webkit-transform: scaleX(-1); 
      transform: scaleX(-1); 
      filter: FlipH;  
}

or

 .your-class{ 
  position:absolute;
  transform: rotate(360deg) scaleX(-1);
}

注意，将位置设置为绝对是非常重要的!如果你不设置它，你需要设置display: inline-block;
