I've been searching for this problem for a while, but since I can't find any working solution I decided to ask. I'm trying to implement some resposiveness to my site.While I use the inspect element tool of google chrome, the background is showed correctly and if I go on it on my mobile phone, the background is actually too zoomed. I've tried to put the scroll attachment, but it doesn't work.
This is the piece regarding the background.
.background2p{
background: url('background2.jpg') fixed no-repeat center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
