I have a HTML, CSS, JS web site and on my computer it works perfect but on my Razer Phone with Chrome it does not scroll vertically. The web site is German but the text doesn´t matter.
If I zoom in it scrolls until the next navigator, then it stops. If I switch in mobile Chrome to desktop site, it scrolls perfect, but in mobile mode it doesn't.
This is because of your
animate.css line 11:
html, body {
overflow: hidden;
}
Try to remove it.
