我正在尝试创建一个具有整页背景图片的网站。我已经让它在桌面版本上工作，但是当我将它推送到github手机上并在手机上查看它时，背景图像只是顶部的一个长图像。我background-size: cover在我的css. 下面的屏幕截图。我怎样才能让它在移动设备上占据整个空间？谢谢 ：）
桌面版：
手机版：
.background1
{
/* Location of the image */
background-image: url(images/background-photo.jpg);
/* Image is centered vertically and horizontally at all times */
background-position: center center;
/* Image doesn't repeat */
background-repeat: no-repeat;
/* Makes the image fixed in the viewpoint so that it doesn't move when
the content height is greater than the image height */
background-attachment: fixed;
/* This is what makes the background image
rescale based on itscontainer's size */
background-size: cover;
/* Pick a solid background color that will
be displayed while the background image is loading */
background-color:#464646;
}
