Question

I am trying to add the fixed background to html page using css which have scrolling front div. But after doing this my JavaScript form not gets loaded. but when I remove that image and clear the css everything works well,

style.css after adding bg image:

html{
width:100%;
height:100%;
position:fixed;
background: url('../images/bg.png') no-repeat center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
}

body{
}
.wrap {
position:absolute;
width:100%;
overflow:scroll;
}

But when I clear it everything works well,

html{
}
body{
}
.wrap {
}
