Question

我想创建一个网站，其中两个部分打开一个向下，一个向上，使用视差。描述第一步的照片 Photo that describe first step

描述第二步的照片 Photo that describe second step

我尝试使用不同的视差框架和纯css视差，但我没有成功。

任何人都有一些想法？

像这样：

＆＃13;

$(window).scroll(function(e){
var scroll = $(window).scrollTop();
var h = $(window).height()/2;
	if (scroll < h){
		$('#wrapper').css({'top':scroll })
	}
  $('#bottom').css({'top': (h + (2* scroll))});
  if (scroll > h){
  	$('#bottom').hide();
  } else {
  	$('#bottom').show();
  }
});

＆＃13;

body {
  overflow-x:hidden;
}
#top, #bottom {
  height:50vh;
  width:100vw;
  padding:0;
  margin:0;
  position:absolute;
  left:0;
  z-index:99;
}
#top {
    top:0;
  background:red;
}
#bottom {
  top:50vh;
  background:green;
}
#wrapper {
  height:5000px;
  position:Relative;
}
