CSS Question

How to properly render and animate svg icons?

I'm trying to use

svg files
and display them as icons. However I'm having some problems


  1. I was unable to load the
    icon.svg
    file inside an
    svg
    tag. I ended up using an
    object
    tag instead.

  2. I would like to add animations to my
    svg
    . I ended up doing it inside the
    icon.svg
    file as such
    <animate dur="5s" values=...; ></animate>
    which throws this error on the browser
    SVG's SMIL animations (<animate>, <set>, etc.) are deprecated and will be removed. Please use CSS animations or Web animations instead.

  3. What is the best way to do all this in jade/html? This is what I have now..

    # footer.tpl.jade

    footer.footer
    +nav
    .logo.logo--footer
    h3.logo__title.logo__title--footer
    a.logo__link(href='/') Frit
    br/
    a.logo__link(href='/') Mark
    p.footer__content All rights reserved or whatever. Please refer to the about section &amp; terms-of-service for the appropriate info. All rights reserved.
    object.icon--heart(type='image/svg+xml', data='icons/heart-icon.svg')

    #_icons.scss

    .icon {

    &--heart {
    width: 25px;
    height: 20px;

    // Will like to add all the animation here

    }
    }



heart-icon.svg

So I figured out how to display icons. Below is my working code. I used this as a reference: SVG sprites & this SVG sprites css tricks

svg-defs.svg
