带有< use>的SVG标签不可见 [英] SVG with <use> tag not visible

问题描述

我对SVG相对陌生，我一直在探索各种在线显示SVG的方法.每个标签似乎都有自己的优缺点，但是<svg>标签本身似乎具有最大的缺点-它不会呈现！

I'm relatively new to SVGs and I've been exploring the various ways to present them in-line. Each seems to have its own pros and cons, but the <svg> tag itself seems to have the biggest drawback - it doesn't render!

我的代码非常简单(引用公共URL SVG):

My code is very simple (referencing a public URL SVG):

<div>
    <svg xmlns="http://www.w3.org/2000/svg">
        <use xlink:href="https://svgshare.com/i/7q9.svg"></use>
    </svg>
</div>

为了确保SVG本身可以使用其他标签，我创建了以下jsFiddle: http://jsfiddle .net/dykv8swr/24/.

To make sure the SVG itself works using other tags, I created the following jsFiddle: http://jsfiddle.net/dykv8swr/24/.

我想念什么?

奖金:作为第二个问题-fill:currentColor似乎不适用于任何SVG类型，似乎也无法弄清楚.

BONUS: As a secondary question - the fill:currentColor doesn't seem to work on any SVG type, can't seem to figure that out either.

谢谢.

推荐答案

如果使用的是fill: currentColor，则必须在SVG的祖先上定义一些color属性.

If you are using fill: currentColor then you have to defined some color property on SVG's ancestor.

第一个问题可能与<svg>上缺少viewBox属性有关.

That first problem can be related to missing viewBox attribute on your <svg>.

我对内联SVG没有任何问题，并且我使用了您所描述的两种方法.

I didn't have any problems with inline SVG and I used both things, which you described.

我更新了您的小提琴，以显示如何以及不使用嵌入式SVG.

I updated your fiddle to show how to and not to use inline SVG.

body {
  display: flex;
}

div {
  border: 1px solid black;
  padding: 25px;
  color: red;
  flex: 0 0 100px;
}

svg,
img,
object,
ico {
  height: 100px;
  width: 100px;
  cursor: pointer;
  fill: red;
}

.icon {
  display: block;
  background-image: url(https://svgshare.com/i/7q9.svg);
  background-repeat: no-repeat;
  background-size: 100px;
  background-position: center;
}
