Full-Screen Responsive Background Image

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%;
}

Accepted Answer

//HTML
<img src="images/bg.jpg" id="bg" alt="">

//CSS
#bg {
  position: fixed; 
  top: 0; 
  left: 0; 

  /* Preserve aspet ratio */
  min-width: 100%;
  min-height: 100%;
}

OR

img.bg {
  /* Set rules to fill background */
  min-height: 100%;
  min-width: 1024px;

  /* Set up proportionate scaling */
  width: 100%;
  height: auto;

  /* Set up positioning */
  position: fixed;
  top: 0;
  left: 0;
}

@media screen and (max-width: 1024px) { /* Specific to this particular image */
  img.bg {
    left: 50%;
    margin-left: -512px;   /* 50% */
  }
}

OR

//HTML
<img src="images/bg.jpg" id="bg" alt="">

//CSS
#bg { position: fixed; top: 0; left: 0; }
.bgwidth { width: 100%; }
.bgheight { height: 100%; }

//jQuery
$(window).load(function() {    

        var theWindow        = $(window),
            $bg              = $("#bg"),
            aspectRatio      = $bg.width() / $bg.height();

        function resizeBg() {

                if ( (theWindow.width() / theWindow.height()) < aspectRatio ) {
                    $bg
                        .removeClass()
                        .addClass('bgheight');
                } else {
                    $bg
                        .removeClass()
                        .addClass('bgwidth');
                }

        }

        theWindow.resize(resizeBg).trigger("resize");

});

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("") no-repeat center center fixed;
}

Answer 5

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;">

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=""></script>

2. Call the method:

$.backstretch("");

I used it for a simple "under construction website" site I had and it worked perfectly.

You can also make full screen banner section without use of JavaScript, pure css based responsive full screen banner section , using height: 100vh; in banner main div, here have live example for this

#bannersection {
    position: relative;
    display: table;
    width: 100%;
    background: rgba(99,214,250,1);
    height: 100vh;
}

Answer 10

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

Sorry for my english... Andrea ;-)

Simple fullscreen and centered image

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%;
    left: -100%;
    top: -100%;
}

.img-fullscreen .full-width {
    width: 100%;
}

.img-fullscreen .full-height {
    height: 100%;
}

<script src=""></script>

<div id="wrapper">
    <div class="img-fullscreen">
        <img src="" alt=""/>
    </div>
</div>

Answer 12

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 13

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.

Answer 14

This worked for me, so posting this.

.my-container {
  position: relative;
  background: #696969;
  overflow: hidden;
}
.my-container:before {
  content: ' ';
  display: block;
  position: absolute;
  left: 0;
  top: 0;
  width: 100%;
  height: 100%;
  z-index: 1;
  opacity: 0.6;
  background-image: url(');
  background-repeat: no-repeat;
  background-position: 50% 0;
  -ms-background-size: cover;
  -o-background-size: cover;
  -moz-background-size: cover;
  -webkit-background-size: cover;
  background-size: cover;
}

Answer 15

By useing this code below :

.classname{
    background-image: url(images/paper.jpg);
    background-position: center;
    background-size: cover;
    background-repeat: no-repeat;
}
