我使用了背景尺寸属性全宽度和高度的背景图像，但无法得到它完全覆盖在Chrome上的Nexus7平板电脑纵向视图。它仅覆盖的宽度，而不是高度，即有一个关于 200像素的下方空白。然而，当我查看该网站的桌面浏览器（或其他），并在垂直显示器模拟画像尺寸覆盖没有问题。

I'm using the background-size property for a full width and height background image but having trouble getting it to fully cover in Chrome on a Nexus7 tablet in portrait view. It only covers the width and not the height i.e. there is about 200px of white space below it. However when I view the site in desktop Chrome (or anything else) and on a vertical monitor to emulate portrait dimensions it covers no problem.

任何人都有一个解决方案吗？

Anyone have a solution?

CSS：

html { 
    background: url(/images/post_bg.jpg) no-repeat center center fixed; 
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    -ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='/images/post_bg.jpg', sizingMethod='scale')";
}

推荐答案

我相信你可以通过定义html和body标签的高度在CSS中，像这样解决这个问题：

I believe you can fix it by defining the height of the html and body tags in the CSS, like so:

html{
 height:100%;
 min-height:100%;
 }
body{
 min-height:100%;
 }

希望这有助于
