使用pointer-event:none创造60fps的滚动体验 From http://www.thecssninja.com/javascript/pointer-events-60fps

disableHover.css

/*
 * 避免子对象覆盖body的设置，因此选择器提高了属性等级另外加了important
 */
.disable-hover,
.disable-hover * {
  pointer-events: none !important;
}

pointerEvent.js

/*
 * 原理是在滚动时将鼠标hover响应禁掉，在停止滚动时再加上
 */
var body = document.body,
    timer;

window.addEventListener('scroll', function() {
  clearTimeout(timer);
  if(!body.classList.contains('disable-hover')) {
    body.classList.add('disable-hover')
  }
  
  timer = setTimeout(function(){
    body.classList.remove('disable-hover')
  },500);
}, false);
