.filter-gradient.green:after{
/* IE9 SVG, needs conditional override of 'filter' to 'none' */
background: url(data:image/svg+xml;base64,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);

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#348f50', endColorstr='#de56b4d3',GradientType=1 ); /* IE6-8 fallback on horizontal gradient */

}

但我需要将渐变更改为 webkit-filter sephia、灰度、hotate、反转、模糊、饱和、对比度... 我无法将渐变更改为 webkit-filter，为什么？谁能帮我或解释一下方法？

谢谢

您的 pseudo-element 缺少 content 属性和任何尺寸...否则它似乎工作正常。

.filter-gradient.green {
  width: 25%;
  height: 100px;
  text-align: right;
  border: 1px solid grey;
}
.filter-gradient.green:after {
  content: '';
  width: 50px;
  height: 100px;
  display: inline-block;
  /* IE9 SVG, needs conditional override of 'filter' to 'none' */
