as you can see in my code example and the screenshot the image won't fit the container even with 100% width or whatever property I try to use. Below you can find my code
.about-us{
background-image: url(images/about-us-background.png);
width: 100%;
height: 100vh;
background-repeat: no-repeat;
}
Even though I have got another section with the same code and it definitely works with the same piece of code. Here I don't see any issue but still, it is not working.web page screenshot
Try to change the width part as it was 100% its stretch up to container width
Example
width: 3vw; (Change according to u)
you should also add background-size:cover;
you can add background-cover : cover or 100% 100% or object-fit : cover in your css
I don't know how to better summarize the question, but here's the problem. I set my html's height to 100% as suggested by Kevin Powell and other peoples best practices so things like the footer and such use the whitespace and stick to the bottom of the page, however it presents the problem that if I want to give my body tag a background-image and the current page is "taller" than the viewport the image will start to repeat every 100% of the viewport, i.e. the 100% set by the html tag, which is not always the desired outcome.
How should I handle this, not to use background-image on my body tag? use a better tiling background-image?
P.S. I don't want to resort to having to wrap all my page's content on a wrapper div inside the body tag... unless well it's the only solution. The body tag has min-height of 100% I'm currently on Firefox.
I think it is easily solvable by using
background-size: cover;

You can also use just the background shorthand to set all the properties at once.

You can set html to occupy 100% of the user's screen by setting min-height: 100vh. then you could set body height to height: 100% to occupy the parent's height (HTML), so this way html and body have the same height if the content is not bigger than 100vh.
If you want to have the same background as you scroll in the page, you can set background-attachment: scroll and background-repeat: no-repeat
something like this
html {
min-height: 100vh;
}
body {
height: 100%;
width: 100%;
background-image: url( /* put your background url here */ );
background-repeat: no-repeat;
background-size: cover;
background-attachment: scroll;
}

I am having trouble keeping a consistent Background image height on a div across multiple devices, I am using Chrome's DevTools to preview the outcome on different devices based on their width. Let me explain further.
I have a div with the following class...
.header-image {
width: 100%;
height: 57%;
background: url('img/fruit-water.jpg') lightgrey;
background-size: 100%;
display: block;
}
This displays perfectly fine on the normal computer viewport, the height: 57%; property displays the perfect amount of the background image that I need. But when I change the view onto another device it doesn't display the same amount of the image that it initially did, it only shows about 20% of the image.
Does anyone know a way to keep the amount of the image displayed consistent, even with the width value changing?
I can't use Jquery or any plugins as the page is an AMP page and validates according to the AMP rules set by google.

Thanks in advance.
as #severinolorillajr said you can use:
background-size:cover;
and if you want to center it to the top you can use:
background-size: cover;
background-position:50% 0%;
EDIT:
Sorry i cannot answer the other question,
if you want to use a % height like 57% you need to set the image position:absolute;
Or you can use:
height:57vh;
That will do the trick!
EDIT2:
maybe you need to mantain the image scale, then you need to set it to:
height:57vw;
.header-image {
background: url('img/fruit-water.jpg') no-repeat center center fixed;
background-size: cover;
}

I was looking at path.com today and liked their implementation of a dynamically sized cover photo. If you check it out you will see that it sizes nicely no matter your screen size.
I looked a little more into it and noticed the background image is attached to the body tag. I also noticed the body appears to get its size from the form element inside it, meaning the body itself it actually shorter than the total page.
Does anyone know how they accomplish this?
Also, the body height is set to 100% of the viewport.
I think you're looking for this part:
body.home {
height: 100%;
background-size: cover;
background-position: center center;
background-repeat: no-repeat;
}
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 ;)
