HTML/CSS Background image scale to 100% - html

I have a large image that I want to set as the background for a 404 page. I want the image to be 100% wide every time someone loads the page, so that if their screen is smaller the image becomes smaller, if the screen is bigger, the image stretches. The height should change based on the width, it doesn't need to be the height of the page.
I don't have the code for this. Would it be better to do it in the HTML file or the CSS file?
Can you possible create a JSfiddle that could serve as an example? Thanks!

Just add this to your CSS code...
body {
background-image:url('http://imageshack.com/scaled/large/268/gjb.png');
background-size:100%,100%;
}
And then create a body...
<body>
Dummy Code
</body>
jsFiddle

This is best left to CSS. Hard to tell without your code exactly, but the following should do what you want:
CSS
html {
height: 100%;
width: 100%;
}
body {
width:100%;
height:100%;
}
#background {
width: 100%;
height: 100%;
background-image: url('http://www.placekitten.com/200/200');
background-repeat: no-repeat;
background-size: 100%;
}
HTML
<div id="background">
<div id="content">
Hello world!
</div>
</div>
UPDATE
See the fiddle here: http://jsfiddle.net/DrydenLong/jywbd/
UPDATE #2
I'd like to point out, just in case those reading through don't see the comments on my post below, that while applying the background-image property directly to the body selector is simpler, it will also apply that same image to every page referencing that CSS file. Should you choose to use a single CSS file for your entire website, my code above will make it easier to have different background images for the 404 page and the rest of the site.

HTML Body content
none
CSS
html {
background: url(http://www.astrophotography.co.nz/Lrg_Slides/20120619Milkyway.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Demo(updated)

I think what you are really looking for is a background-attachment property.
body {
background-image:url('http://IMAGEURL');
background-attachment:fixed;
width: 100%;
}
You dont need to setup height property here, it's done for you automatically.

How about this:
body{background:url(http://www.astrophotography.co.nz/Lrg_Slides/20120619Milkyway.jpg) 0 0 no-repeat; background-size:100% auto;}

I can't figure out why 100% width doesn't work with a background image

I'm trying to create a webpage. I'm having a little difficulty
with getting my background picture to show up. I had it up and running, but I decided I wanted to give it a responsive design, and I can't figure it out. This is my code for the image:
<style>
body .title_img {
background-image: url("SplashScreen.jpg");
height: auto;
width: 100%;
background-position: center;
z-index: -1;
}
</style>
<div class="title_img">
<!-- Background Splash Screen -->
</div>
If I give the height/width a definitive size (pixels) it shows up. I don't understand why 100% width with auto height wouldn't give me a picture that is 100% the size of the body (which I THINK i have made sure it was the 100% of the html document) and a height that is automatically proportional to the width. Can someone explain what I'm doing wrong?
EDIT- Added the HTML code.
Full-Page Background Images
I think what you are trying to create, is a full-page background image for your website. Based off of reading the code you provided, I believe you want something that does the following:
Fills entire page with image, no white space
Scales image as needed
Retains image proportions (aspect ratio)
Image is centered on page
Does not cause scrollbars
As cross-browser compatible as possible
Isn't some fancy shenanigans like Flash
If that is what you are trying to create, then I found a few lines of code that could help. Here is an example of how you could go about doing this with your image using css:
CSS File (That's where the magic happens):
html {
background: url("SplashScreen.jpg") no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Just make sure your html file is setup correctly to use the css file, and it should create a cool background image you can use for your websites.
You can read more into this here and learn more about what makes this work.
Try setting height: 100% in body and html in your css:
html, body {
height: 100%;
}
And then put background-size: cover in body .title_img:
body .title_img {
background-image: url("SplashScreen.jpg");
height: 100%;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
z-index: -1;
}
See reference here.
Use
background-size: cover
or
background-size:100% 100%.
with
background-repeat: no-repeat
That will set it to 100% of its container.

How to display a gif fullscreen for a webpage background?

I'm trying to make a GIF fit my whole screen, but so far its just a small square that is on my screen while the rest is white. However, I want it to take up all the space.
Any ideas?
if it's background, use background-size: cover;
body{
background-image: url('http://i.stack.imgur.com/kx8MT.gif');
background-size: cover;
height: 100vh;
padding:0;
margin:0;
}
IMG Method
If you want the image to be a stand alone element, use this CSS:
#selector {
width:100%;
height:100%;
}
With this HTML:
<img src='folder/image.gif' id='selector'/>
Fiddle
Please note that the img tag would have to be inside the body tag ONLY. If it were inside anything else, it may not fill the entire screen based on the other elements properties. This method will also not work if the page is taller than the image. It will leave white space. This is where the background method comes in
Background Image Method
If you want it to be the background image of you page, you can use this CSS:
body {
background-image:url('folder/image.gif');
background-size:100%;
background-repeat: repeat-y;
background-attachment: fixed;
height:100%;
width:100%;
}
Fiddle
Or the shorthand version:
body {
background:url('folder/image.gif') repeat-y 100% 100% fixed;
height:100%;
width:100%;
}
Fiddle
You can set up a background with your GIF file and set the body this way:
body{
background-image:url('http://www.example.com/yourfile.gif');
background-position: center;
background-size: cover;
}
Change background image URL with your GIF. With background-position: center you can put the image to the center and with background-size: cover you set the picture to fit all the screen. You can also set background-size: contain if you want to fit the picture at 100% of the screen but without leaving any part of the picture without showing.
Here's more info about the property:
http://www.w3schools.com/cssref/css3_pr_background-size.asp
Hope it helps :)
if you're happy using it as a background image and CSS3 then background-size: cover; would do the trick
This should do what you're looking for.
CSS:
html, body {
height: 100%;
margin: 0;
}
.gif-container {
background: url("image.gif") center;
background-size: cover;
height: 100%;
}
HTML:
<div class="gif-container"></div>
In your CSS Style tag put this:
body {
background: url('yourgif.gif') no-repeat center center fixed;
background-size: cover;
}
Also make sure that it's parent size is 100%

HTML background-image not showing on screen

I am trying to create an full width image above my nav bar, but I cant even get the image to show on screen. Here is my simple HTML:
<html>
<body>
<div class="wrapper" />
</body>
</html>
And the css:
.wrapper {
background-image: url(../assets/bridge.jpg);
background-repeat: no-repeat;
background-size: 100%;
width: 100%;
height: 100%;
}
I see the jpg made it to my browser and can click on it in my resources, so there is no problem with the path. The screen is still blank and showing nothing. Any help would be awesome.
This is because height:100% is functionally useless, and your div resultingly has no height.
If you give the div a fixed height, the image should appear as expected.
Alternatively if you want the background image to apply to the background of the page, you can apply it to the <html> element and avoid the whole wrapper, 100% debacle.
html {
background-image: url(../assets/bridge.jpg);
background-repeat: no-repeat;
background-size: 100%;
}
http://jsfiddle.net/dolours/JcxLm/2/ Give a specific height, Height 100% is meaningless
.wrapper {
background-image: url(../assets/bridge.jpg);
background-repeat: no-repeat;
background-size: 100%;
width: 100%;
height: 50px;
}
try this <div class="wrapper"></div>
It is possible that the image isn't showing because there is no content within the div and therefore it's size is 0. Try setting the width and height to a set size, something like 200px to test out this theory. Also I would change your code to:
<div class="wrapper"> </div>
you can use css for body tag, the css of body will be like this:
body{
background: url(../assets/bridge.jpg) center top no-repeat;
}
i think it will work for you, if you want just background image.

How to make a full width image responsive

I have an image that is my header. Here is my simple HTML:
<html>
<body>
<div class="wrapper" />
</body>
</html>
It fills the full width of the page, but I had to specify a height for it show up. Here is the css:
.wrapper {
background-image: url(../assets/bridge.jpg);
background-repeat: no-repeat;
background-size: 100%;
width: 100%;
height: 250px;
}
How do I make this image responsive? Right now when I expand the page it gets to the point where the pic is unrecognizable.
Didn't got your question quiet well, but I think you are missing a value here
background-size: 100%; /* 1 value is not wrong but you'll probably need 2 */
--^---
CSS
.wrapper {
background-image: url(http://images.google.co.in/intl/en_ALL/images/logos/images_logo_lg.gif);
background-repeat: no-repeat;
background-size: 100% 100%;
width: 100%;
height: 250px;
}
Demo
As ralph.m suggested, if you are using this image as your website background, than use the background property on body element instead of div
You need to use following CSS to make the background responsive
body {
background: url(bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Reference Link
You need to think carefully about how you want/expect this to work. Without some actual content in the div, it will have zero height, which is why you needed to set a height on it; but in general, try to avoid setting heights. Presumably, if this is a "wrapper", it will be wrapping some content that will hold it open without you having to set a height.
As for the background image, you need to think about how it will behave. Do you just want it to appear in a strip along the top? If you use Mr Alien's solution, be aware that the image will stretch wider and wider and start to look odd. So we need some more information on what you are trying to do here.

HTML/CSS background-image not displaying?

I am just trying to set my background but this image will not work. It is between 15 to 20MB in size so I tried to turn it into 5MB. Still no luck. I made a really small image, 25KB size, and that worked but just repeated. My localhost will not show big images either. Is there some limit? What do I need to do to get a full image page?
body {
background-image:url(background.jpg);
}
Do this to avoid repeating the image:
body
{
background-image:url(background.jpg);
background-repeat:no-repeat;
}
You can also experiment with background-size: cover like this:
body
{
background-image: url("http://www.google.com/doodle4google/images/carousel-winner2012.jpg");
background-repeat: no-repeat;
background-position: center center;
-moz-background-size: cover;
-webkit-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-attachment: fixed;
}
Here's a demo at JS Bin with a beautiful Doodle 4 Google as the background image to test the behavior:
http://jsbin.com/ivexah/2
you need to assign a width and height to body.
for example:
html, body {
width: 100%;
height: 100%;
}
You can use the shorthand background css property:
background: url(background.jpg) no-repeat;
Also your body might not have a height of 100% because there's no content on your page. Either give your html and body a height of 100% or add more content to your page.
To make a background image cover its entire container use background-size:
background-size: cover;
IE8 and lower don't support this. For those browsers you need a javascript fallback. There's an excellent article on css-tricks.com that shows different techniques.
You shouldn't have any "size" limitation on your background image. More than likely, you're file is so large that you are not waiting long enough for it to load OR you have not set a width and height. Without the dimensions, the element tahat you are trying to load the background image will essentially have a size of 0px x 0px. See the following jsfiddle example:
http://jsfiddle.net/GymxW/1/
The HTML:
<div class="container"></div>
The CSS:
.container {
width: 400px;
height: 100px;
background-image: url(http://dummyimage.com/400x100/4d494d/686a82.gif&text=background+image);
background-repeat: none;
background-position: 0 0;
}
IMPORTANT: If you are wanting to have an image that is "stretched" to the full size of the viewport, a simple solution is to use a plugin, such as Backstretch.
