All modern browsers are supported. Proxy mobile browsers like Opera Mini are not
supported.

### IE11

IE11 (and other older browsers) is supported with the following polyfills:

- `Promise`
- `Object.assign`
- `Array.prototype.find`

If not already polyfilling these in your app, the following script tag using the
polyfill.io service placed before Tippy's scripts will polyfill these.

```html
<script src=""></script>
```

It won't add extra cost (besides a negligible bundle size and HTTP request) to
browsers that already support those built-in APIs.

#### SVG in IE11

If you need to support SVG elements in IE11, you will need to include a polyfill
for `SVGElement.prototype.contains`.

The polyfill is small:

```js
if (!SVGElement.prototype.contains) {
  SVGElement.prototype.contains = HTMLDivElement.prototype.contains;
}
```
