Firefox支持:
不幸的是,只有WebKit浏览器实现了text-fill-color.
目前还没有针对Mozilla的解决方法.

HTML和CSS代码:

<h1>hello</h1>

h1 {
  font-size: 72px;
  background: -webkit-linear-gradient(#eee, #333);
  -webkit-background-clip: text;
  -webkit-text-fill-color: transparent;
}

CSS3 Gradient无法在Firefox中运行

您可以使用位于彼此顶部的多个跨距,并为每个跨距指定不同的高度和颜色.它的编码非常难看,但它确实有效. http://jsfiddle.net/7yBNv/

文本选择表现得有点时髦,但也不算太糟糕.复制复制几个条目(取决于选择的层)所以我说你最好用svg来解决这个问题.
