SVG图标:基于上下文使用CSS进行样式设置

标签: css svg icons

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?

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;
}
