background-size: cover not working in portrait on Android tablet

maceyj2 picture maceyj2 · Feb 14, 2013 · Viewed 59k times · Source

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.

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')";
}

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%;
 }

hope this helps
