just saw a question
Can the animate animation library of Css3 set the animation effect when scrolling the screen?
you can try this
①Try Swiper Animate
②Using animate.css and then cooperating with wow.js can solve this problem perfectly without writing scroll wheel events
③Full-screen sliding is generally used for this effect on official websites. There are many plug-ins that can achieve this effect, such as swiper, fullpage, iscroll, etc.
