在悬停时更改 css 背景图像 svg 绘制行为？

Question

我使用 svg 作为按钮的背景图像。

该按钮需要不同的悬停状态，这只是对 svg 填充值的更改。

是否有一种聪明的方法可以对 svg 进行这些更改，该更改实际上仅用作图像，或者我是否需要创建具有不同填充颜色的不同 svg 文件？

Answer 1

另一种带有背景位置的方法。

HTML

<div class="locate">
    <a href="#">lorem ipsum</a>
</div>

CSS

 .locate a {
      padding-left: 20px;
      position: relative;
      text-decoration: underline;
      color: #000;
    }
    .locate a:before {
      width: 16px;
      height: 16px;
      content: "";
      background: transparent url('search.svg') no-repeat scroll 0 0;
      -webkit-background-size: 16px 32px;
      background-size: 16px 32px;
      position: absolute;
      top: 0;
      left: 0;
      /* For screen reader */
      speak: none;
    }
    .locate a:hover,
    .locate a:focus {
      color: #a2005a;
      text-decoration: none;
    }
    .locate a:hover:before,
    .locate a:focus:before {
      background-position: 0 -16px;
    }

SVG

Answer 2

是的，您可以使用 SVG 内联。 不适用于 IE 11。

<p class="loupe"><a href="#">Lorem ipsum</a></p>

.loupe a {

Answer 3

如果您使用 SVG 作为背景图像，它不会是交互式的。 把它想象成非常像一个光栅图像。 拥有两个图像当然是一种解决方案。
