真正的镜子:

.mirror { 显示:inline-block; 字体大小:30 px; -webkit-transform:矩阵(-1,0,0,1,0,0); -moz-transform:矩阵(-1,0,0,1,0,0); -o-transform:矩阵(-1,0,0,1,0,0); 变换:矩阵(-1,0,0,1,0,0); ｝ <span class='mirror'>镜像文本

您可以使用CSS转换来实现这一点。水平翻转会像这样缩放div:

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

垂直翻转会涉及到div的缩放，就像这样:

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

演示:

Span{显示:inline-block;保证金:1 em;｝ .flip_H{转换:规模(- 1,1);颜色:红色;｝ .flip_V{转换:规模(1，-1);颜色:绿色;｝ <span class='flip_H'>演示文本&#9986 <span class='flip_V'>演示文本&#9986

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;

我在网上搜罗了包括

Stack Overflow回答， MSDN文章, http://css-tricks.com/almanac/properties/t/transform/, http://caniuse.com/搜索=变换, http://browserhacks.com/, http://www.useragentman.com/IETransformsTranslator/。

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.

  @see http://msdn.microsoft.com/en-us/library/ms532992%28v=vs.85%29.aspx
*/

/* 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);
}

真正的镜子:

.mirror { 显示:inline-block; 字体大小:30 px; -webkit-transform:矩阵(-1,0,0,1,0,0); -moz-transform:矩阵(-1,0,0,1,0,0); -o-transform:矩阵(-1,0,0,1,0,0); 变换:矩阵(-1,0,0,1,0,0); ｝ <span class='mirror'>镜像文本

你可以试试box-reflect

box-reflect: 20px right;
