### scrollToTop
Smooth-scrolls to the top of the page.
Get distance from top using `document.documentElement.scrollTop` or `document.body.scrollTop`.
Scroll by a fraction of the distance from the top. Use `window.requestAnimationFrame()` to animate the scrolling.
```js
const scrollToTop = () => {
const c = document.documentElement.scrollTop || document.body.scrollTop;
if (c > 0) {
window.requestAnimationFrame(scrollToTop);
window.scrollTo(0, c - c / 8);
}
};
```
```js
scrollToTop();
```
