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. 我无法在icon.svg标记中加载svg文件。最后，我使用了一个object标记。
2. 我想添加动画到我的svg。最后，我在icon.svg文件中这样做了，<animate dur="5s" values=...; ></animate>在浏览器SVG's SMIL animations (<animate>, <set>, etc.) are deprecated and will be removed. Please use CSS animations or Web animations instead.上抛出了这个错误。
3. 在翡翠/html中，最好的方法是什么？这就是我拥有的now..footer.tpl.jade footer.footer +nav .logo.徽标--页脚h3.href_Title.LOGO__ a.logo__link(href='/') Frit / a.logo__link(href='/')标记p.footer__content所有保留的权利或任何东西。有关资料，请参阅有关资料及服务条款.版权所有。对象.图标--心脏(type=‘image/svg+xml’，data=‘icons/Hear-ic.svg’)版权(2016年比利时)。#_icons.scss .icon {&-心{宽度:25 to；高度:20 to；//将在这里添加所有动画}

heart-icon.svg

所以我想出了如何显示图标。下面是我的工作代码。我用它作为参考：SVG精灵 &这个SVG精灵css技巧
