### 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);
|
|
}
|
|
};
|
|
// scrollToTop()
|
|
```
