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