## 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 opacity 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.
|
|
|
|
```css
|
|
/* Style */
|
|
#mySVG * {
|
|
fill-opacity: 0;
|
|
transition: fill-opacity 1s;
|
|
}
|
|
|
|
#mySVG.finished * {
|
|
fill-opacity: 1;
|
|
}
|
|
```
|
|
|
|
```js
|
|
/* JavaScript */
|
|
new Vivus('mySVG', {}, function (obj) {
|
|
obj.el.classList.add('finished');
|
|
});
|
|
```
|
|
|
|
**WARNING**: This hack cannot work on sandboxed solutions like the use of `object` tag.
