Full-screen responsive background image - css

Question

I am very new to Front-end development and Foundation.
I am trying to get <div class="main-header"> to be a full screen image that scales down responsively.
Can anyone tell me what I am doing wrong? It is scaling properly, but is not showing the full image. I also wanted the <div class="large-6 large-offset-6 columns"> to sit above it on a mobile device – is that possible?
The HTML:
<!-- MAIN HEADER -->
<div class="main-header">
<div class="row">
<div class="large-6 large-offset-6 columns">
<h1 class="logo">BleepBleeps</h1>
<h3>A family of little friends<br>that make parenting easier</h3>
</div> <!-- END large-6 large-offset-6 columns -->
</div><!-- END ROW -->
</div><!-- END MAIN-HEADER -->
The CSS:
.main-header {
background-image: url(../img/bb-background2.png);
background-repeat: no-repeat;
background-position: center;
background-size: cover;
width: 100%;
height: 100%;
}
h1.logo {
text-indent: -9999px;
height:115px;
margin-top: 10%;
}

Answer 3

for Full-screen responsive background image
set css height ( height:100vh )
example :
.main-header {
background-image: url(../img/bb-background2.png);
background-repeat: no-repeat;
background-position: center;
background-size: cover;
width: 100%;
height:100vh; /* responsive height */
}

Answer 4

One hint about the "background-size: cover" solution, you have to put it after "background" definition, otherwise it won't work, for example this won't work:
html, body {
height: 100%;
background-size: cover;
background:url("http://i.imgur.com/aZO5Kolb.jpg") no-repeat center center fixed;
}

I personally dont recommend to apply style on HTML tag, it might have after effects somewhere later part of the development.
so i personally suggest to apply background-image property to the body tag.
body{
width:100%;
height: 100%;
background-image: url("./images/bg.jpg");
background-position: center;
background-size: 100% 100%;
background-repeat: no-repeat;
}
This simple trick solved my problem. this works for most of the screens larger/smaller ones.
there are so many ways to do it, i found this the simpler with minimum after effects

Answer 6

I had this same problem with my pre-launch site EnGrip. I went live with this issue. But after a few trials finally this has worked for me:
background-size: cover;
background-repeat: no-repeat;
position: fixed;
background-attachment: scroll;
background-position: 50% 50%;
top: 0;
right: 0;
bottom: 0;
left: 0;
content: "";
z-index: 0;
pure CSS solution. I don't have any JS/JQuery fix over here. Even am new to this UI development. Just thought I would share a working solution since I read this thread yesterday.

Answer 7

Try this:
<img src="images/background.jpg"
style="width:100%;height:100%;position:absolute;top:0;left:0;z-index:-5000;">

Answer 8

Backstretch
Check out this one-liner plugin that scales a background image responsively.
All you need to do is:
1. Include the library:
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/jquery-backstretch/2.0.4/jquery.backstretch.min.js"></script>
2. Call the method:
$.backstretch("http://dl.dropbox.com/u/515046/www/garfield-interior.jpg");
I used it for a simple "under construction website" site I had and it worked perfectly.

}

I have done this javascript function: it fix your background image to your screen size in base at the most significative dimension (width od height) without change the image aspect ratio.
<script language="Javascript">
function FixBackgroundToScreen()
{
bgImg = new Image();
bgImg.src = document.body.background;
if ((bgImg.height / window.innerHeight) < (bgImg.width / window.innerWidth))
document.body.style.backgroundSize = "auto 100%";
else
document.body.style.backgroundSize = "100% auto";
};
</script>
This function is the only think you need. It must be called with the window.onresize event and from the body.onload event. The image must be background-repeat: no-repeat; background-attachment: fixed;
<script language="Javascript">
window.onresize=function(){FixBackgroundToScreen();};
</script>
<body onload="FixBackgroundToScreen();">
You can see the function in my site www.andreamarulla.it
Sorry for my english...

Simple fullscreen and centered image
https://jsfiddle.net/maestro888/3a9Lrmho
jQuery(function($) {
function resizeImage() {
$('.img-fullscreen').each(function () {
var $imgWrp = $(this);
$('img', this).each(function () {
var imgW = $(this)[0].width,
imgH = $(this)[0].height;
$(this).removeClass();
$imgWrp.css({
width: $(window).width(),
height: $(window).height()
});
imgW / imgH < $(window).width() / $(window).height() ?
$(this).addClass('full-width') : $(this).addClass('full-height');
});
});
}
window.onload = function () {
resizeImage();
};
window.onresize = function () {
setTimeout(resizeImage, 300);
};
resizeImage();
});
/*
* Hide scrollbars
*/
#wrapper {
overflow: hidden;
}
/*
* Basic styles
*/
.img-fullscreen {
position: relative;
overflow: hidden;
}
.img-fullscreen img {
vertical-align: middle;
position: absolute;
display: table;
margin: auto;
height: auto;
width: auto;
bottom: -100%;
right: -100%;

}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="wrapper">

</div>

Answer 13

For the full-screen responsive background image cover
<div class="full-screen">
</div>
CSS
.full-screen{
background-image: url("img_girl.jpg");
height: 100%;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}

Answer 14

I would say, in your layout file give a
<div id="background"></div>
and then in your css do
#background {
position: fixed;
top: 50%;
left: 50%;
min-width: 100%;
min-height: 100%;
width: auto;
height: auto;
z-index: -100;
-webkit-transform: translateX(-50%) translateY(-50%);
transform: translateX(-50%) translateY(-50%);
background: image-url('background.png') no-repeat;
background-size: cover;
}
And be sure to have the background image in your app/assets/images and also change the
background: image-url('background.png') no-repeat;
'background.png' to your own background pic.

.classname{
background-image: url(images/paper.jpg);
