html - 如何正确渲染和动画 svg 图标？

Question

我正在尝试使用 svg files并将它们显示为图标。但是我遇到了一些问题

1. 我无法加载 icon.svg svg 中的文件标签。我最终使用了 object标签代替。

2. 我想为我的 svg 添加动画.我最终在 icon.svg 中完成了它文件本身 <animate dur="5s" values=...; ></animate>这会在浏览器上引发此错误 SVG's SMIL animations (<animate>, <set>, etc.) are deprecated and will be removed. Please use CSS animations or Web animations instead.

3. 在 jade/html 中做这一切的最好方法是什么？这就是我现在拥有的..

    # footer.tpl.jade
   
    footer.footer
      +nav
      .logo.logo--footer
       h3.logo__title.logo__title--footer
         a.logo__link(href='/') Frit
         br/

    .icon {
   
      &--heart {
        width: 25px;
        height: 20px;
   
        // Will like to add all the animation here
   
      }
    }

所以我想出了如何显示图标。下面是我的工作代码。我用这个作为引用:SVG sprites &这个SVG sprites css tricks
