I am having trouble with centering a background behind a div. I have made a fiddle showing how the background image stays center whilst the browser window is resized, which is great, but if the scrollbar is moved down so to view the bottom of the green div, the back ground follows the scroll, so is no long centered, which I am trying to avoid. I hope for the center text of the bk-gnd image to remain central in the view port at all times, whether resizing the screen or scrolling, is this possible?
here is the interactive fiddle : http://jsfiddle.net/4fM2n/
CSS
html, body {
height: 100%;
margin: auto;
}
#bk-gnd-div {
height: 100%;
background-image: url('http://oi58.tinypic.com/5an82h.jpg');
margin: auto;
background-repeat: no-repeat;
background-position: center center;
background-color: #9FBBE2;
}
the other div code is on the fiddle, stackoverflow is saying it is not formatted correctly and wont let me post it? maybe this is a clue?
add css
*{
margin: 0;
padding: 0;
}
#bk-gnd-div {
margin: 0 auto;
width: 100%;
}
or image fixed center
body {
width: 100%;
height: 100%;
background-image:url('http://oi58.tinypic.com/5an82h.jpg');
margin:0 auto;
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
}

I'm setting up a site, and want to create a responsive background image but I'm getting only single line with background image. What property should i need to use to make the entire background image to fit?
I created 2 files,
index.html :
<div id="logo">Test</div>
style.css :
#logo {
background-image: url("bg.png");
background-position: center center;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
}
I tried many times but only single line gets background image. I want the background image to be fully displayed on screen without using height property which i think makes site less responsive.
you should change the height of logo div and set it as full height by adding height:100% for the body and logo div, your code should look like below code
html, body
{
height: 100%;
}
#logo {
background-image: url("bg.png");
background-position: center center;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
height:100%;
}
If you want the image to have the same height as the screen you can use height:100vh. But if you want only the image full size you can do this like this :
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#image{
max-height: 100%;
max-width: 100%;
}
#text{
position: absolute;
color: white;
top: 0
}

<div id="text">test</div>
I'm trying to set the size (both width and height) of a div to match it's background image size, but I can't get it working.
The background image size has to be in percentages, because I'm dealing with a responsive website. On smaller screens, the background should be displayed completely (with less width, but still proportional), and the div who has the image should follow that size.
I tried various values of the background-size, such as auto 100%, cover, contain, etc. but nothing did the trick.
There's a similar question here about this: scale div to background image size but it didn't solve my problem either.
I'd really appreciate if someone knows how to do it.
EDIT:
I made a fiddle to show the behavior: http://jsfiddle.net/osv1v9re/5/
This line is what is making the background image so small:
background-size: auto 100%;
But if it is removed is removed, the background will fill the proper width, but not the height.
tag cannot adapt to background-image size, you need to use an tag and choose between height: auto for the div or javascript
// **** Problem ****
// Wrong html :
<div class="my_class"><div>
// with css :
.my_class {
width: 100%;
height: 100%;
background-image: url(/images/my-image.jpg);
background-size: 100%;
background-position: center;
background-repeat: no-repeat;
}
//**** Solution ****
// use css:
.my_class {
width: 100%;
height: 100%;
background-image: url(/images/my-image.jpg);
background-size: contain;
}
*{
padding: 0;
margin: 0;
}
div{
width: 100%;
}
div figure{
padding-top: 36.56%; /* 702px/1920px = 0.3656 */
display: block;
background: url("https://st.fl.ru/images/landing/bg2.jpg") no-repeat center top;
background-size: cover;
}
<div>
<figure></figure>
</div>
you can have a responsive height using the padding-bottom or padding-top
because you can't fix an height property in '%' with a width in '%'.
div{
background-image: url(url);
background-repeat: no-repeat;
background-size: 100% 100%;
background-position: center;
margin: 0 auto;
width: 100%;
padding-bottom: heightPicure / widthPicture + %; //do it manually or using scss rules
}
I was looking for a solution to make my opening background image to be 100% of the viewport and after using Josh powel''s answer here Page height to 100% of viewport? it works on chrome on mac but not on any other browser (on mac or windows) When I say 'it works on chrome on mac', it works in most instances however if I stretch the browser too high, it doesn't fit to cover and I see my next bit of content so it's like it only works for heights up to x...
here's my code:
<section class="intro">
<div class="intro-body">
</div>
</section>
.intro {
display: table;
width: 100%;
height: 100%;
padding: 350px 0 330px;
text-align: center;
color: #fff;
position: relative;
background: url(http://www.wallsave.com/wallpapers/1920x1200/plain-blue-gradient/2567400/plain-blue-gradient-pc-mac-hd-2567400.jpg) no-repeat center;
background-size:cover;
}
.intro-page {
padding: 150px 0 130px;
background: url(http://www.wallsave.com/wallpapers/1920x1200/plain-blue-gradient/2567400/plain-blue-gradient-pc-mac-hd-2567400.jpg) no-repeat center;
background-size: cover;
}
function windowH() {
var wH = $(window).height();
$('.intro, .intro-page').css({height: wH});
}

If anyone can shed any light, that'd be great.
In order to make an element 100% height of the page, you must also have:
html,body { height: 100%; min-height: 100%; }
It's much better and more reliably to do this in CSS than by using JS.
Alternatively, you could just put the background image on the body (with background-size: cover like you are using).
I've got this logo I'm trying to use on a responsive site, but I can't figure out how to have it so it fills the full width of its parent element while maintaining its ratio in height.
When you start resizing the browser window, the logo gets smaller in width but its height doesn't scale properly. Is there a way to maintain this.
Here's my CSS for the logo element:
h1 {
width: 100%;
height: auto;
background: url(http://images.uncyclomedia.co/uncyclopedia/en/thumb/c/ce/Coca-Cola_logo.svg/800px-Coca-Cola_logo.svg.png) no-repeat top left orange;
background-size: contain;
text-indent: -999999px;
text-align: center;
margin-top: 270px;
}
This is the problem I'm having. Look at all that extra space below the
logo.
And here's a CodePen with an example of my issue:
http://codepen.io/realph/pen/LAFsi
Any help with this is appreciated. Thanks in advance!
You could use a padding trick (see CSS-square container) to do what you want with one image
h1 {
background: url(http://images.uncyclomedia.co/uncyclopedia/en/thumb/c/ce/Coca-Cola_logo.svg/800px-Coca-Cola_logo.svg.png) no-repeat top left orange;
background-size: contain;
text-indent: -999999px;
text-align: center;
position:relative;
width:100%;
height: 0;
padding-bottom: 30%;
display:block;
}
Demo
I have this background, the css code is:
body {
background: #FFF url('images/bg.png') no-repeat bottom center;
margin-bottom: -500px;
width: 100%;
height: 100%;
color:#999;
}
The image is 400px tall, and I would like to make it align to the bottom of the page.
So far, this only works in Firefox. In Chrome and IE the background position is at top center, instead of bottom center.
You need to make the html element height 100% too:
html, body {
height: 100%; width: 100%;
padding: 0; margin: 0;
}
body {
background: #FFF url(images/bg.png) no-repeat bottom center;
}
Also, negative margins don't work in IE6/7 (not sure about IE8)
