  可以预加载图片，教程中预加载的图片错了，应该是这样的

  .b_background {

  width: 100%;

  height: 100%;

  background-image: url("../images/QixiB-dark.png");

  background-size: 100% 100%;

  position: absolute;

  }

  
  

  .b_background_preload {

    <!-- 预加载灯亮效果图-->

      background: url("../images/QixiB-bright.png") no-repeat -9999px -9999px;

  }

  
  

  .lamp-bright{

  background-image: url("../images/QixiB-bright.png");

  }
