Background Width jQuery Specification Not Working

I created a web page where the background of my page changes depending on the hour. I want the background image to always be the full width of the page, so I am trying to set it to be 100%, but it doesn't seem to be working. Is there some part of the code that's written incorrectly? Do I need to implement something else?



body {
margin-left: 5%;
margin-right: 5%;
}
#demo {
color: white;
}
#txt {
color: white;
float: left;
font-family: OpenSans;
font-size: 90px;
margin: 20px;
}
#weather {
color: white;
float: right;
font-family: OpenSans;
font-size: 40px;
margin: 20px;
}

Answer

You could try removing the margin attributes on the body tag in your CSS, and set background-size: cover on the body tag there. Then in your changeBackground function, you mightn't need the .width(100%); method, since the width shouldn't change when you swap out the background images?
