固定背景固定和位置固定元素的Chrome问题

在以下位置找到了此解决方案

在我看来，使用：before伪元素是一种聪明的方法。限制固定宽度元素的宽度，但对全角页面效果很好。本质上看起来像这样：

.background_fill {  overflow: hidden;  position: relative;    color: red;}.background_fill:before {  background-color: white;  background: url('http://www.lausanneworldpulse.com/pdfs/brierley_map_0507.jpg') no-repeat center center;  background-size: cover;  z-index: -3;  content: " ";  position: fixed;  will-change: transform;  width: 100%;  height: 100%;}<div >  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div>  <div>this is on a background / this is on a background / this is on a background / this is on a background / this is on a background / this is on a background</div></div>
