Animate fill with CSS

On inline SVG, it's very easy to animate fill color with just a bit of CSS.

Let's imagine you have an inline SVG element in your page with the ID mySVG. You apply the following CSS to make it with fill opcaity to 0 by default, and a class with the opacity of 1 (with transition). Then once the animation finished, the class can be added to the svg.

/* Style */
#mySVG * {
  fill-opacity: 0;
  transition: fill-opacity 1s;
}

#mySVG.finished * {
  fill-opacity: 1;
}

/* JavaScript */
new Vivus('mySVG', {}, function (obj) {
  obj.el.classList.add('finished');
});
