是否可以使用CSS 根据其上下文设置SVG图标的路径？
我的SVG图标由两条路径组成：
<g id="shape-codepen">
<path class="outer-ring" d="..."></path>
<path class="inner-logo" d="..."></path>
</g>
我在HTML中使用它们如下：
<svg class="shape-codepen"><use xlink:href="#shape-codepen"></use></svg>
<svg class="shape-codepen-red"><use xlink:href="#shape-codepen"></use></svg>
基本款式：
.outer-ring { fill: #999; }
.inner-logo { fill: #666; }
但我想改变第二个的部分颜色，因为它在不同的环境中，即
.shape-codepen-red .outer-ring { fill: #f00; }
但是不起作用。
这是一个简单的笔记码插图我的问题： http://codepen.io/anon/pen/eZVGgv
是否可以根据图标的上下文更改图标路径的部分颜色？怎么样？
答案 0 :(得分：0)
不......你无法访问这样的内部部件。您需要两个use元素。一个用于戒指，另一个用于内部形状。
然后单独解决。
.hide {
display: none;
}
.icon {
width: 75px;
height: 75px;
}
body {
padding: 20px;
}
.red .red {
fill: red;
}
.blue .blue {
fill: blue;
}<svg class="hide">
