好的。 我试图制作一个适用于所有浏览器的视差网站。我已经在所有浏览器上实现了效果，但在某些浏览器中它滞后且跳跃。有没有办法让它变得光滑？
这是我的代码
function Draw(){
requestAnimationFrame(Draw);
scrollEvent();
}
Draw();
function scrollEvent(){
var height = $(window).height();
if($(document).scrollTop() <= height){
$('#home').css('transform', 'translate3d(0, ' + ($(document).scrollTop() + 'px, 0)'));
$('#about').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - height + 'px, 0)'));
}else if($(document).scrollTop() <= 2*height){
$('#about').css('transform', 'translate3d(0, ' + ($(document).scrollTop() -height + 'px, 0)'));
$('#gallery').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - 2*height + 'px, 0)'));
}else if($(document).scrollTop() <= 3*height){
$('#gallery').css('transform', 'translate3d(0, ' + ($(document).scrollTop() -2*height + 'px, 0)'));
$('#blog').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - 3*height + 'px, 0)'));
}else if($(document).scrollTop() <= 4*height){
$('#blog').css('transform', 'translate3d(0, ' + ($(document).scrollTop() -3*height+ 'px, 0)'));
$('#contact').css('transform', 'translate3d(0, ' + ($(document).scrollTop() - 4*height + 'px, 0)'));
}
