var box = document.querySelector('.box');
var currentPos = window.pageYOffset; //滚动条距离顶部高度
var update = function () {
var newPos = window.pageYOffset;
var diff = newPos - currentPos; //判断是向下滚动还是向上滚动
var speed = diff * 0.2; //倾斜幅度
box.style.transform = 'skewY(' + speed + 'deg)'; //倾斜角度
currentPos = newPos;
window.requestAnimationFrame(update);
};
update();
