As you can see, I have a body with an offset for the header and the body has an image background. However, the image is not being show in full.
Question:
Can I do something with CSS so that the whole image is shown or do I need to use Gimp or photoshop to scale down my image. Currently it is 1400 x 1050 pixels.
I think you are trying to make the image fit the window even if that means the image is distorted.
You can achieve this with background-size property you have already used. But instead of cover you set it to 100% 100%. Live example: http://jsbin.com/opokev/21/
body {
background: url(http://i53.tinypic.com/347a8uu.jpg) no-repeat center fixed;
background-position: 0px 85px;
-webkit-background-size: 100% 100%;
-moz-background-size: 100% 100%;
-o-background-size: 100% 100%;
background-size: 100% 100%;
}
CSS2 does now allow you to scale background images. You can use a media query through and present a different image, based on the user's resolution.
BTW: Quotes are not required for URL parameters:
background-image: url(http://s1.postimage.org/gkkq9uc17/Sketch2.jpg);
In your example, the image is not being shown at all. I suspect this is because you are using postimage.org to host the image, and they are blocking the image request from an external domain (your example). If I substitute the URL for an image hosted on my own server, the image background is displayed using the attributes you have set. I would suggest using a different image host.
The CSS3 background-size: cover; attribute that you are using will scale the image proportionally to fill the browser, based on the horizontal width. There should be no need to scale the image beforehand, although this may not always give you the prettiest result.
Yes you can do some trick using HTML and CSS, but your image must to be in tag:
CSS:
html, body, #body { height:100% }
#body { position:relative }
img {
position:absolute;
width:100%;
height:100%;
display:block;
z-index:1;
}
div#masthead {
background-color: #262626;
height: 85px;
padding: 0;
width: 100%;
margin: 0;
z-index:2;
position:relative
}
HTML:
<body>
<img src="http://i53.tinypic.com/347a8uu.jpg">
<div id="masthead"></div>
</body>

This seems to be a common question but the existing answers I see do not seem to work for me. I have a background image that is much taller than it is wide. I would like the height to be 100% of the height of body. So far I have tried:
body, html {
height: 100%;
min-height: 100%;
}
body {
background:url("NewLogo.png") no-repeat center center;
background-size: 100% auto;
}
I have also tried changing background-size: cover; but this also just makes the image large but cuts off the top and bottom.
Use contain. This will guarantee that the entire image appears in the container, and nothing is cut off:
body {
background:url("NewLogo.png") no-repeat center center;
background-size: contain;
}
Please note that if you want to have a background image which is cover and has got it's own height (without just being large, as wide as your browser but loosing the top & bottom as you said), you can try giving an appropriate height in vh to your background image.
body {
margin: 0;
}
#image {
background-image: url(https://images.unsplash.com/photo-1504387103978-e4ee71416c38?auto=format&fit=crop&w=2134&q=60&ixid=dW5zcGxhc2guY29tOzs7Ozs%3D);
background-repeat: no-repeat;
height: 293vh;
background-size: cover;
}
<div id="image">
</div>
Otherwise if you just want to make your background image cover, or if you want make it contain(though your image wouldn't fit the browser wide, it would be in it's real height), you can visit the following link:

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.
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.
Say, like in this example here: http://www.electrictoolbox.com/examples/wide-background-image.html
When I do it, I end up getting white borders around the image no matter what I do. What am I doing wrong?
If you're hoping to use background-image: url(...);, I don't think you can. However, if you want to play with layering, you can do something like this:
<img class="bg" src="..." />
And then some CSS:
.bg
{
width: 100%;
z-index: 0;
}
You can now layer content above the stretched image by playing with z-indexes and such. One quick note, the image can't be contained in any other elements for the width: 100%; to apply to the whole page.
Here's a quick demo if you can't rely on background-size: http://jsfiddle.net/bB3Uc/
Background images, ideally, are always done with CSS. All other images are done with html. This will span the whole background of your site.
body {
background: url('../images/cat.ong');
background-size: cover;
background-position: center;
background-attachment: fixed;
}
You set the CSS to :
#elementID {
background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) center no-repeat;
height: 200px;
}
It centers the image, but does not scale it.
FIDDLE
In newer browsers you can use the background-size property and do:
#elementID {
height: 200px;
width: 100%;
background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) no-repeat;
background-size: 100% 100%;
}
FIDDLE
Other than that, a regular image is one way to do it, but then it's not really a background image.
the problem is the margin of body his default value is margin: 8px
and i make it margin : 0 so the image stretching and there is no white places
I'm currently working on a mobile landing page for a company. It's a really basic layout but below the header there's an image of a product which will always be 100% width (the design shows it always going from edge to edge). Depending on the width of the screen the height of the image will obviously adjust accordingly. I originally did this with an img (with a CSS width of 100%) and it worked great but I've realised that I'd like to use media queries to serve different images based on different resolutions - let's say a small, medium and a large version of the same image, for example. I know you can't change the img src with CSS so I figured I should be using a CSS background for the image as opposed to an img tag in the HTML.
I can't seem to get this working properly as the div with the background image needs both a width and a height to show the background. I can obviously use 'width: 100%' but what do I use for the height? I can put a random fixed height like 150px and then I can see the top 150px of the image but this isn't the solution as there isn't a fixed height. I had a play and found that once there is a height (tested with 150px) I can use 'background-size: 100%' to fit the image in the div correctly. I can use the more recent CSS3 for this project as it's aimed solely at mobile.
I've added a rough example below. Please excuse the inline styles but I wanted to give a basic example to try and make my question a little clearer.
<div id="image-container">
<div id="image" style="background: url(image.jpg) no-repeat; width: 100%; height: 150px; background-size: 100%;"></div>
</div>
Do I maybe have to give the container div a percentage height based on the whole page or am I looking at this completely wrong?
Also, do you think CSS backgrounds are the best way to do this? Maybe there's a technique which serves different img tags based on device/screen width. The general idea is that the landing page template will be used numerous times with different product images so I need to make sure I develop this the best way possible.
I apologise is this is a little long-winded but I'm back and forth from this project to the next so I'd like to get this little thing done.
Tim S. was much closer to a "correct" answer then the currently accepted one. If you want to have a 100% width, variable height background image done with CSS, instead of using cover (which will allow the image to extend out from the sides) or contain (which does not allow the image to extend out at all), just set the CSS like so:
body {
background-image: url(img.jpg);
background-position: center top;
background-size: 100% auto;
}
This will set your background image to 100% width and allow the height to overflow. Now you can use media queries to swap out that image instead of relying on JavaScript.
EDIT: I just realized (3 months later) that you probably don't want the image to overflow; you seem to want the container element to resize based on it's background-image (to preserve it's aspect ratio), which is not possible with CSS as far as I know.
Hopefully soon you'll be able to use the new srcset attribute on the img element. If you want to use img elements now, the currently accepted answer is probably best.
However, you can create a responsive background-image element with a constant aspect ratio using purely CSS. To do this, you set the height to 0 and set the padding-bottom to a percentage of the element's own width, like so:
.foo {
height: 0;
padding: 0; /* remove any pre-existing padding, just in case */
padding-bottom: 75%; /* for a 4:3 aspect ratio */
background-image: url(foo.png);
background-position: center center;
background-size: 100%;
background-repeat: no-repeat;
}
In order to use different aspect ratios, divide the height of the original image by it's own width, and multiply by 100 to get the percentage value. This works because padding percentage is always calculated based on width, even if it's vertical padding.
Try this
html {
background: url(image.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Simplified version
html {
background: url(image.jpg) center center / cover no-repeat fixed;
}
Instead of using background-image you can use img directly and to get the image to spread all the width of the viewport try using max-width:100%;.
Please remember; don't apply any padding or margin to your main container div as they will increase the total width of the container. Using this rule, you can have a image width equal to the width of the browser and the height will also change according to the aspect ratio.
Edit: Changing the image on different size of the window
$(window).resize(function(){
var windowWidth = $(window).width();
var imgSrc = $('#image');
if(windowWidth <= 400){
imgSrc.attr('src','http://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a');
}
else if(windowWidth > 400){
imgSrc.attr('src','http://i.stack.imgur.com/oURrw.png');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="image-container">
<img id="image" src="http://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.png?v=c78bd457575a" alt=""/>
</div>
In this way you change your image in different size of the browser.
You can use the CSS property background-size and set it to cover or contain, depending your preference. Cover will cover the window entirely, while contain will make one side fit the window thus not covering the entire page (unless the aspect ratio of the screen is equal to the image).
Please note that this is a CSS3 property. In older browsers, this property is ignored. Alternatively, you can use javascript to change the CSS settings depending on the window size, but this isn't preferred.
body {
background-image: url(image.jpg); /* image */
background-position: center; /* center the image */
background-size: cover; /* cover the entire window */
}
Just use a two color background image:
<div style="width:100%; background:url('images/bkgmid.png');
background-size: cover;">
content
</div>
Add the css:
html,body{
height:100%;
}
.bg-img {
background: url(image.jpg) no-repeat center top;
background-size: cover;
height:100%;
}
And html is:
<div class="bg-mg"></div>
CSS: stretching background image to 100% width and height of screen?
It's 2017, and now you can use object-fit which has decent support. It works in the same way as a div's background-size but on the element itself, and on any element including images.
.your-img {
max-width: 100%;
max-height: 100%;
object-fit: contain;
}
html{
height:100%;
}
.bg-img {
background: url(image.jpg) no-repeat center top;
background-size: cover;
height:100vh;
}
I was also facing your problem. Two solutions come to my mind through HTML and CSS :
Solution 1) HTML img tag
.img-container {
width: 100%;
border: 1px solid #000;
}
.img-container img {
width: 100%;
pointer-events: none;
}
<div class="img-container">
<img src="https://i.postimg.cc/ht1YnwcD/example.png">
</div>
Solution 2) CSS background image
First find width and height of your image file, you can right click on your image and choose Properties then go to details tab. you can see your image dimensions (according to the picture).
enter image description here
Then remember them.
.img-container {
width: 100%;
// height: calc(100vw / (your image width / image height));
height: calc(100vw / (812 / 133));
background-image: url('https://i.postimg.cc/ht1YnwcD/example.png');
background-position: top;
background-repeat: no-repeat;
background-size: 100% auto;
border: 1px solid #000;
}
<div class="img-container"></div>
I hope it was useful ;)
