I have been working on positioning a background image, but the image is only positioned correctly while the webpage window is adjusted to its minimum width. As I resize the browser window the image is clipped on all of its' side lengths. The photo has a height much greater than its width(1391 x 2471). I thought I might have to incorporate a vertical scroll? The website is being designed for mobile platforms but I will be viewing and designing it primarily on a computer monitor. How might I maintain the images' integrity from Min. Width of browser to Max. Width of browser?
* { margin: 0;
padding: 0;
}
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;
}
My CSS code for the positioning of the image was taught to me on CSS-Tricks though it has provided the best results so far. I have added a link to the image encase you would like to view. It is a photo I took myself so I hope the link provided is functional.
You need to get the html element (or whatever element you want the img to show in) to have at least the full height of the img when the img has full width (100vw) of the viewport.
You can do that if you know the aspect ratio of the image. In this case you know the natural width and height of the original so the aspect ratio can be calculated by CSS if you give it those dimensions as variables.
Here's an example using your CSS settings (except see caveat below):
* {
margin: 0;
padding: 0;
}
html {
--imgw: 1391;
--imgh: 2471;
width: 100vw;
min-height: calc(100vw * var(--imgh) / var(--imgw));
/* make sure the whole height of the image is always shown */
background-image: url(https://picsum.photos/id/1015/1391/2471);
background-size: cover;
}
HELLO
Caveat: you have background fixed in your CSS. Two problems with that: it renders the element unscrollable and in any case it is not properly supported in Safari and makes the background look 'fuzzy' on IOS. So this snippet has removed it.
body{
background: url("");
background-repeat: no-repeat;
background-size: cover;
background-position: center;
background-attachment: fixed;
}
If I have understood this properly, you want the image to be displayed properly on all the sizes you want?
Well in that case you can use #media query.
#media(max-width: your max width in px) {
/*And here change the height and width so that it doesn't look weird*/
}
all.
I am trying to set an image as the background inside a div container which will always have the dimensions of the screen of the device. For this purpose, I am providing the css as follows
.outer {
height: 100vh;
background-image: url(demo_top.jpg);
background-repeat: no-repeat;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-position: center;
}
<body>
<div class='outer'>
</div>
</body>
The positive of this code:
-Image quality is maintained.
The negatives of this code:
-Background image is not responsive as the focus is only on centre
-The top and the bottom part of the images are cropped because the position is used as the centre.
What I am looking for is my div to display the entire image without any cropping or image stretching or distortion.
The image size I am using is 2000x2000
If you want the image to have the same dimensions as your container, you have to use the same image proportions. In this case, the container must also be square (1x1). If the proportions of both elements are not equal, the only solution is to stretch one side of the image or to cut it.
https://developer.mozilla.org/es/docs/Web/CSS/object-fit
Instead of background-size: cover, you need to use contain. This will allow the image to be as large as possible without cropping outside the div and with no stretching/distoring.
-webkit-background-size:contain;
-moz-background-size:contain;
-o-background-size:contain;
background-size:contain;
I have made a background image, 1366px wide and 768px high, which I want to use as background for the main page of my website.
I have each page of my website divided in sections, using the FullPage plugin.
This is the main page so I'm using just the first section.
What I've tried so far is adding this CSS code to the #first section of my main page:
#first{
width: 500px;
height: 500px;
background-image: url(images/ClanshnowXmasEventSmall.jpg) no-repeat center center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
Unfortunately the image gets displayed just partially. In fact it's a little shorter than it actually is.
I read the documentation for the background-size attribute, and at the cover attribute it says:
Scale the background image to be as large as possible so that the background area is completely covered by the background image. Some parts of the background image may not be in view within the background positioning area
So basically how can I make my background-image fit the screen size? Considering the mobile side I think it would be better to fit just the width of it. I'm open for suggestions and help!

Good luck!
I have a design that I'm converting to be Bootstrap responsive but have run into a couple of problems.
How to make a non full width background image responsive
How to keep the main form content the correct distance away from the top of the image no matter what the viewport size.
Mock up image
Website
I'd be very grateful for any pointers
The following is one simple option, according to your mockup-Website.
Create a parent DIV that is center aligned on the page.
Apply a background image to this DIV and set its max-width to 100%.
Create another div that will sit on top of the parent DIV (and is relative to the parent DIV).
Give its top margin the required %.
It is recommended that you create these styles on media queries for responsive display.
There are a lot of StackOverflow topics the will help you through with the above steps.
HTH.
To fix problem 1: on the body you can use: background-size:contain;
First, for the background image:
div.someclass{
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
This will make your background image responsive, i.e. it will fit according to the size of the display the page is viewed on.
Second, to keep the main form content a proper margin from above on any device is to give the div you just created for the main content a relative margin on top:
div.someclass{
margin-top:5%;
}
change the above 5% according to your requirement.
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 ;)
