html - 如何在 CSS 中设置一个特定的 SVG 路径的样式？

Question

是否可以使用 2 个不同的 CSS 类对同一个 SVG 符号设置不同的样式。就像在这个 jsfiddle 中一样

.shape-55 {
  width: 55px;
  height: 55px;
}
/* Want to color only the first path in red */
.shape-style-1 path:nth-of-type(1) {
  fill: red;
}
/* Want to color only the first path in blue */
.shape-style-2 path:nth-of-type(1) {
  fill: blue;
}

<!-- SVG Spritesheets-->
<svg class="shape" style="display:none;">
  <symbol viewBox="0 0 64 64" id="shape-1">
    <title>sw_av_a_tkn-cscd</title>

<div>
  <svg class="shape-55 shape-style-2">

  </svg>
</div>

我需要在使用 CSS 类 shape-style-1 时将第一个“路径”着色为红色，在使用 shape-style-2 时将其着色为蓝色。

谢谢。

Answer 1

您可以设置父级 div 的颜色样式，并使用 fill: currentColor 将该颜色用于适当的 SVG 元素。

所以这个 CSS:

div > svg {
  width: 55px;
  height: 55px;
}

svg g g > path:nth-of-type(1) {
  fill: currentColor;
}

div:nth-of-type(even) {
  color: red;
}

div:nth-of-type(odd) {
  color: blue;
}

...与此 HTML 一起使用:

<div><svg><use xlink:href="#shape-1"></use></svg></div>
<div><svg><use xlink:href="#shape-1"></use></svg></div>
<div><svg><use xlink:href="#shape-1"></use></svg></div>
<div><svg><use xlink:href="#shape-1"></use></svg></div>

……看起来像这样:
