The background image shows perfectly on PC and simulator (tablet and phone), but it won't show on actual phone/tablet.
code
div#photo_break {
@include viewport-unit(height, 28vw);
background-image: url('<img>');
background-repeat: no-repeat;
background-size: 100% auto;
-webkit-background-size: 100% auto;
-moz-background-size: 100% auto;
-o-background-size: 100% auto;
background-position: center top;
background-attachment: fixed;
z-index: 99999;
}
As you can see in this picture, in Chromes simulator
the picture is shown.
The size of the image is not really large, or is it?
mobile
and tablet browsers
do not support background-attachment: fixed
.
changing this, solved the problem
