html - 使用 css 操作 svg 颜色

Question

我制作了一个 svg 图标用于在 illustrator 中搜索，并想在我的网站中使用它。我把它放在html中可以看到图标。

<div id="search-btn">
    <img src="svg/search.svg">
</div>

但是因为我把它做成了黑色，所以我想改变放大镜和背景的颜色。如何使用 css 操作 svg 的颜色？我是 svg 的新手，您的帮助将非常宝贵。谢谢。

搜索图标:

svg代码:

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"

Answer 1

正如这个答案的评论中所说

CSS does not apply cross-document and the img is a separate document. Images must be self contained in a single file to preserve privacy. – Robert Longson

所以这意味着您将无法在您的 img 标签中包含您的 SVG 并在页面上使用 CSS 对其进行自定义。所以你有两个选择:

内联 SVG 代码，这意味着废弃 img 标签。然后，您可以按如下方式定位 SVG。

#search-btn svg {
  fill: blue;
  background: grey;
  width: 100px;
  }

<div id="search-btn">
  <svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 100 100" style="enable-background:new 0 0 100 100;" xml:space="preserve">
    <path id="XMLID_10_" d="M98.2,89.7L63,54.5c-0.1-0.1-0.1-0.1-0.2-0.2c4-5.6,6.3-12.4,6.3-19.8c0-19-15.4-34.4-34.4-34.4
    c-19,0-34.4,15.4-34.4,34.4c0,19,15.4,34.4,34.4,34.4c7.3,0,14-2.3,19.6-6.1c0.1,0.1,0.1,0.2,0.2,0.3l35.2,35.2
    c2.4,2.4,6.2,2.4,8.5,0l0,0C100.6,95.9,100.6,92.1,98.2,89.7z M7.3,34.5c0-15.1,12.3-27.4,27.4-27.4c15.1,0,27.4,12.3,27.4,27.4
    c0,15.1-12.3,27.4-27.4,27.4C19.6,61.9,7.3,49.6,7.3,34.5z" />
  </svg>
</div>

或者您可以向 SVG 文件本身添加样式，如下所示，但这类似于在 Illustrator 中简单地编辑文件以获得您想要的颜色。

<div id="search-btn">
  <svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 100 100" style="enable-background:new 0 0 100 100;" xml:space="preserve">
    <defs>
      <style>
        #XMLID_10_ {
          fill: blue;
        }
      </style>
    </defs>
    <path id="XMLID_10_" d="M98.2,89.7L63,54.5c-0.1-0.1-0.1-0.1-0.2-0.2c4-5.6,6.3-12.4,6.3-19.8c0-19-15.4-34.4-34.4-34.4
    c-19,0-34.4,15.4-34.4,34.4c0,19,15.4,34.4,34.4,34.4c7.3,0,14-2.3,19.6-6.1c0.1,0.1,0.1,0.2,0.2,0.3l35.2,35.2
    c2.4,2.4,6.2,2.4,8.5,0l0,0C100.6,95.9,100.6,92.1,98.2,89.7z M7.3,34.5c0-15.1,12.3-27.4,27.4-27.4c15.1,0,27.4,12.3,27.4,27.4
    c0,15.1-12.3,27.4-27.4,27.4C19.6,61.9,7.3,49.6,7.3,34.5z" />
  </svg>
