+Smooth-scrolls to the top of the page.

+- Get distance from top using `Document.documentElement` or `Document.body` and `Element.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(); // Smooth-scrolls to the top of the page
+```
