Background Issue

I have changed the background on my theme to the following in style.css
html {
background:url(http://www.desinext.com/wp-content/uploads/2014/11/stadium1.jpg);
}

The background works fine on the computer but on mobile i lose the white background on the posts and i cannot read the posts dude to text being on top of the background i added.
