问题 I have a container: scroll-snap-points-y: repeat(100%); snap-type: mandatory; snap-type: y mandatory; And three children: height: 100%; scroll-snap-align: center; scroll-snap-stop: always; This works just as expected in Firefox, but there seems to be a threshold for snapping in Chrome. When scrolling just a small amount, Chrome will snap back to the first child, while Firefox will scroll to the next child. Only after scrolling about 30% of the child height, Chrome will snap to the next one.

问题 I'm trying to detect if the scroll event is up or down but I can't find the solution. import React, { useState, useEffect } from "react"; import { Link } from "react-router-dom"; const Navbar = ({ className }) => { const [y, setY] = useState(0); const handleNavigation = (e) => { const window = e.currentTarget; if (y > window.scrollY) { console.log("scrolling up"); } else if (y < window.scrollY) { console.log("scrolling down"); } setY(window.scrollY); }; useEffect(() => { setY(window.scrollY);

问题 Using react-visibility-sensor I've created a higher component to animate the sections of my project on scroll. I'm having problems trying to make it work only on the first scroll. At the moment the sections appear and disappear. Any help would be really appreciated.

问题 This only happens in iPhone-sized Safari. I am aware that the "usual fix" for this issue is to apply -webkit-transform: translate3d(0,0,0); (per Serge's answer here) and that does fix the issue, but only once. The issue occurs with a "drawer" menu that opens when the user clicks a menu button. The menu will show normally, but when it is touched/scrolled by a finger, the whole menu disappears from the page.
