指南针背景图像(线性渐变)不在IE上工作

Question

使用SASS和Compass完成此渐变在任何版本的Internet Explorer中都不起作用:

@include background-image(linear-gradient(left, rgba(241,236,236,0.95), rgba(241,236,236,0.9), rgba(241,236,236,0.85), rgba(241,236,236,0.8), rgba(241,236,236,0.75), rgba(241,236,236,0.4)));

它转换为这个CSS:

  background-image: -webkit-gradient(linear, 0% 50%, 100% 50%, color-stop(0%, rgba(241, 236, 236, 0.95)), color-stop(20%, rgba(241, 236, 236, 0.9)), color-stop(40%, rgba(241, 236, 236, 0.85)), color-stop(60%, rgba(241, 236, 236, 0.8)), color-stop(80%, rgba(241, 236, 236, 0.75)), color-stop(100%, rgba(241, 236, 236, 0.4)));
  background-image: -webkit-linear-gradient(left, rgba(241, 236, 236, 0.95), rgba(241, 236, 236, 0.9), rgba(241, 236, 236, 0.85), rgba(241, 236, 236, 0.8), rgba(241, 236, 236, 0.75), rgba(241, 236, 236, 0.4));
  background-image: -moz-linear-gradient(left, rgba(241, 236, 236, 0.95), rgba(241, 236, 236, 0.9), rgba(241, 236, 236, 0.85), rgba(241, 236, 236, 0.8), rgba(241, 236, 236, 0.75), rgba(241, 236, 236, 0.4));
  background-image: -o-linear-gradient(left, rgba(241, 236, 236, 0.95), rgba(241, 236, 236, 0.9), rgba(241, 236, 236, 0.85), rgba(241, 236, 236, 0.8), rgba(241, 236, 236, 0.75), rgba(241, 236, 236, 0.4));
  background-image: linear-gradient(left, rgba(241, 236, 236, 0.95), rgba(241, 236, 236, 0.9), rgba(241, 236, 236, 0.85), rgba(241, 236, 236, 0.8), rgba(241, 236, 236, 0.75), rgba(241, 236, 236, 0.4));

那你用IE做什么来解决这个问题呢？

我正在用Internet Explorer 11测试它.我需要它从IE9 +开始工作

在下面的帮助下我找到了覆盖IE10 +的答案,这对我有所帮助:

background: -ms-linear-gradient(left, rgba(241,236,236,0.95), rgba(241,236,236,0.9), rgba(241,236,236,0.85), rgba(241,236,236,0.8), rgba(241,236,236,0.75), rgba(241,236,236,0.4)); /* IE10+ */

我尝试以下IE9后,但没有工作:

filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#f1ecec', endColorstr='#fffafa',GradientType=1 );

我可以用什么来掩盖烦人的IE9？

Answer 1

您必须使用 IE6-9 的过滤器，如下所示：

filter: progid:DXImageTransform.Microsoft.gradient(...)

对于 IE10+

-ms-linear-gradient

我相信IE6-9可能只支持2个色标。我能给你的最好的帮助就是：

很棒的工具，适合这个东西:)

如果你将 css“导入”到工具中，你会得到：

支持 IE9 的完整多级渐变（使用 SVG）。向所有具有渐变的元素添加一个“渐变”类，并将以下覆盖添加到 HTML 以完成 IE9 支持：

<!--[if gte IE 9]>
  <style type="text/css">
    .gradient {
       filter: none;
    }
  </style>
<![endif]-->

...甚至是 SCSS 版本

// needs latest Compass, add '@import "compass"' to your scss
@include filter-gradient(#f2f1ecec, #66f1ecec, vertical); // IE6-8
// IE9 SVG, needs conditional override of 'filter' to 'none'
$experimental-support-for-svg: true;
@include background-image(linear-gradient(top,  rgba(241,236,236,0.95) 0%,rgba(241,236,236,0.75) 80%,rgba(241,236,236,0.4) 100%));
