I'm using the code below to display an image as a background in a div. How do I resize it?
#header {
height: 255px;
-webkit-background-size:cover;
-moz-background-size:cover;
background-size:cover;
background-position: 50% 50%;
background-image: url('../simg/header.png');
}
You can try controlling the size of the background by using the background-size property.
E.g.:
#header {
height: 255px;
-webkit-background-size:50%;
-moz-background-size:50%;
background-size:50%;
background-position: 50% 50%;
background-image: url('../simg/header.png');
}
This will reduce the background image to exactly half in either dimension.
try Easy Background Resize .js http://johnpatrickgiven.com/jquery/background-resize/
Another approach you can try is to set the css
background-size:contain;
width:50%;
max-height:255px;
and let the browser figure out the height which results in it maintaining the aspect ratio.

I have a website (g-floors.eu) and I want to make the background (in css I have defined a bg-image for the content) also responsive. Unfortunately I really don't have any idea on how to do this except for one thing that I can think of but it's quite a workaround. Creating multiple images and then using css screen size to change the images but I wanna know if there is a more practical way in order to achieve this.
Basically what I wanna achieve is that the image (with the watermark 'G') automatically resizes without displaying less of the image. If it's possible of course
link: g-floors.eu
Code I have so far (content part)
#content {
background-image: url('../images/bg.png');
background-repeat: no-repeat;
position: relative;
width: 85%;
height: 610px;
margin-left: auto;
margin-right: auto;
}
If you want the same image to scale based on the size of the browser window:
background-image:url('../images/bg.png');
background-repeat:no-repeat;
background-size:contain;
background-position:center;
Do not set width, height, or margins.
EDIT:
The previous line about not setting width, height or margin refers to OP's original question about scaling with the window size. In other use cases, you may want to set width/height/margins if necessary.
by this code your background image go center and fix it size whatever your div size change , good for small , big , normal sizes , best for all , i use it for my projects where my background size or div size can change
background-repeat:no-repeat;
-webkit-background-size:cover;
-moz-background-size:cover;
-o-background-size:cover;
background-size:cover;
background-position:center;
Try this :
background-image: url(_images/bg.png);
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
background-size: cover;
CSS:
background-size: 100%;
That should do the trick! :)
Here is sass mixin for responsive background image that I use. It works for any block element. Of course the same can work in plain CSS you will just have to calculate padding manually.
#mixin responsive-bg-image($image-width, $image-height) {
background-size: 100%;
height: 0;
padding-bottom: percentage($image-height / $image-width);
display: block;
}
.my-element {
background: url("images/my-image.png") no-repeat;
// substitute for your image dimensions
#include responsive-bg-image(204, 81);
}
Example http://jsfiddle.net/XbEdW/1/
This is an easy one =)
body {
background-image: url(http://domains.com/photo.jpeg);
background-position: center center;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
}
Take a look at the jsFiddle demo
Here is the best way i got.
#content {
background-image:url('smiley.gif');
background-repeat:no-repeat;
background-size:cover;
}
Check on the w3schools
More Available options
background-size: auto|length|cover|contain|initial|inherit;
#container {
background-image: url("../images/layout/bg.png");
background-repeat: no-repeat;
background-size: 100% 100%;
height: 100vh;
margin: 3px auto 0;
position: relative;
}
I used
#content {
width: 100%;
height: 500px;
background-size: cover;
background-position: center top;
}
which worked really well.
Responsive website by add padding into bottom image height/width x 100 = padding-bottom %:
http://www.outsidethebracket.com/responsive-web-design-fluid-background-images/
More complicated method:
http://voormedia.com/blog/2012/11/responsive-background-images-with-fixed-or-fluid-aspect-ratios
Try to resize background eq Firefox Ctrl + M to see magic nice script i think best one:
http://www.minimit.com/demos/fullscreen-backgrounds-with-centered-content
You can use this. I have tested and its working 100% correct:
background-image:url('../images/bg.png');
background-repeat:no-repeat;
background-size:100%;
background-position:center;
You can test your website with responsiveness at this Screen Size Simulator:
http://www.infobyip.com/testwebsiteresolution.php
Clear Your cache each time you make changes and i would prefer to use Firefox to test it.
If you want to use an Image form other site/URL and not like:
background-image:url('../images/bg.png');
//This structure is to use the image from your own hosted server.
Then use like this:
background-image: url(http://173.254.28.15/~brettedm/wp-content/uploads/Brett-Edmonds-Photography-14.jpg) ;
Enjoy :)
<style>
* {
padding: 0;
margin: 0;
box-sizing: border-box;
}
#res_img {
background: url("https://s15.postimg.org/ve2qzi01n/image_slider_1.jpg");
width: 100%;
height: 500px;
background-repeat: no-repeat;
background-size: 100% 100%;
background-position: center;
border: 1px solid red;
}
#media screen and (min-width:300px) and (max-width:500px) {
#res_img {
width: 100%;
height: 200px;
}
}
</style>
<div id="res_img">
</div>
If you want the entire image to show irrespective of the aspect ratio, then try this:
background-image:url('../images/bg.png');
background-repeat:no-repeat;
background-size:100% 100%;
background-position:center;
This will show the entire image no matter what the screen size.
background:url("img/content-bg.jpg") no-repeat;
background-position:center;
background-size:cover;
or
background-size:100%;
Just two lines of code, it works.
#content {
background-image: url('../images/bg.png');
background-size: cover;
}
Adaptive for square ratio with jQuery
var Height = $(window).height();
var Width = $(window).width();
var HW = Width/Height;
if(HW<1){
$(".background").css("background-size","auto 100%");
}
else if(HW>1){
$(".background").css("background-size","100% auto");
}
background: url(/static/media/group3x.6bb50026.jpg);
background-size: contain;
background-repeat: no-repeat;
background-position: top;
the position property can be used to align top bottom and center as per your need and background-size can be used for center crop(cover) or full image(contain or 100%)
I think, the best way to do it is this:
body {
font-family: Arial,Verdana,sans-serif;
background:url("/images/image.jpg") no-repeat fixed bottom right transparent;
}
In this way there's no need to do nothing more and it's quite simple.
At least, it works for me.
I hope it helps.
Try using background-size but using TWO ARGUMENTS One for the width and the other one for the height
background-image:url('../images/bg.png');
background-repeat:no-repeat;
background-size: 100% 100%; // Here the first argument will be the width
// and the second will be the height.
background-position:center;
I have a div with an unknown width. I want it to have a large background image.
How do I set the background image width to be as the width of the div itself? (the height of the div is known).
Background size will work, but the aspect ratio of the image will be changed. 500px below is the known height.
.myDiv {
background-image: url(image.png);
background-repeat: no-repeat;
background-size: 100% 500px;
}
More info on background-size here, it's not supported on <= IE8.
Or alternatively you could absolutely position an image relative to the container, but background-size is better.
img.cover {
width:100%;
height:100%;
position:absolute:
top:0;
left:0;
right:0;
bottom:0;
z-index:-1;
}
.myDiv {
background-image: url(image.png);
background-repeat: no-repeat;
background-size: contain; (you could also use cover here)
}
Use background image in the div and background-size css propierty.
Example:
#im {
background-image: url("path/to/img");
background-repeat: no-repeat;
background-size: cover;
}
You can also set the image width to 100% to fill your content div. In order to use height 100% you need specify your div height.
The following CSS attributes will make the background width fit to a dynamic container:
.myDiv {
background-size: 100%; /* fit width to container */
background-repeat: no-repeat; /* do not repeat background */
height: 200px; /* height is known */
}
See an example on JSFiddle
Just as the title says. How can I get a background image, or even text to fill width wise, not stretch/squash vertically, and just show up once? I can't seem to figure this out. Thank you.
Edit: I also want the height to scale with the width of the picture proportionally, so it will not be skewed but scaled with the width.
If you only want the background img to fill the width without taking into account the height you can do:
.element-with-back-img{
background-repeat: no-repeat;
background-size: 100%;
}
but with this the img doesn't fill the height of element-with-back-img because the height will set to "auto"
By doing this:
.element-with-back-img{
background-repeat: no-repeat;
background-size: 100% 100%;
}
the img fills the height but if element-with-back-img has different proportions than those from the img, this one will change its proportions to fill the element-with-back-img
I recommend u to:
.element-with-back-img{
background-repeat: no-repeat;
background-size: cover;
}
this 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
I hope this could help u
.test {
background-image: url(http://placekitten.com/1000/750);
background-size: 100%;
background-repeat: no-repeat;
background-color: lightblue;
height: 150px;
display: inline-block;
}
#test1 {
width: 200px;
}
#test2 {
width: 100px;
}
#test3 {
width: 300px;
}
.test:hover {
background-position: center center;
}
<div class="test" id="test1"></div>
<div class="test" id="test2"></div>
<div class="test" id="test3"></div>
Use css for the body:
body {background-repeat: no-repeat;
background-size: 100%;}
To fill width-wise, use 'background-size'. That allows you to enter two parameters - width and height, in that order. Use '100%' to fill the width, then a fixed value for the height (assuming you know what the height of your image is).
E.g. if your background image is 500px tall, then:
{
background-size:100% 500px;
background-repeat: no-repeat;
}
You can experiment for yourself here.
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%
I have
body {
background: url(images/background.svg);
}
The desired effect is that this background image will have width equal to that of the page, height changing to maintain the proportion. e.g. if the original image happens to be 100*200 (any units) and the body is 600px wide, the background image should end up being 1200px high. The height should change automatically if the window is resized. Is this possible?
At the moment, Firefox looks like it's making the height fit and then adjusting the width. Is this perhaps because the height is the longest dimension and it's trying to avoid cropping? I want to crop vertically, then scroll: no horizontal repeat.
Also, Chrome is placing the image in the centre, no repeat, even when background-repeat:repeat is given explicitly, which is the default anyway.
There is a CSS3 property for this, namely background-size (compatibility check). While one can set length values, it's usually used with the special values contain and cover. In your specific case, you should use cover:
body {
background-image: url(images/background.svg);
background-size: cover; /* <------ */
background-repeat: no-repeat;
background-position: center center; /* optional, center the image */
}
Eggsplanation for contain and cover
Sorry for the bad pun, but I'm going to use the picture of the day by Biswarup Ganguly for demonstration. Lets say that this is your screen, and the gray area is outside of your visible screen. For demonstration, I'm going to assume a 16x9 ratio.
We want to use the aforementioned picture of the day as a background. However, we cropped the image to 4x3 for some reason. We could set the background-size property to some fixed length, but we will focus on contain and cover. Note that I also assume that we didn't mangle the width and/or height of body.
contain
contain
Scale the image, while preserving its intrinsic aspect ratio (if any), to the largest size such that both its width and its height can fit inside the background positioning area.
This makes sure that the background image is always completely contained in the background positioning area, however, there could be some empty space filled with your background-color in this case:
cover
cover
Scale the image, while preserving its intrinsic aspect ratio (if any), to the smallest size such that both its width and its height can completely cover the background positioning area.
This makes sure that the background image is covering everything. There will be no visible background-color, however depending on the screen's ratio a great part of your image could be cut off:
Demonstration with actual code

background-image: url(http://i.stack.imgur.com/r5CAq.jpg);
background-repeat: no-repeat;
background-position: center center;

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me
body {
overflow-y: hidden ! important;
overflow-x: hidden ! important;
background-color: #f8f8f8;
background-image: url('index.png');
/*background-size: cover;*/
background-size: contain;
background-repeat: no-repeat;
background-position: right;
}
Background image is not Set Perfect then his css is problem create so his css file change to below code
html {
background-image: url("example.png");
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
}
%; background-size: 100% 100%;"
I'm not sure what you're looking for exactly, but you really should check out these excellent blog posts written by Chris Coyier from CSS-Tricks:
http://css-tricks.com/how-to-resizeable-background-image/
http://css-tricks.com/perfect-full-page-background-image/
Read the descriptions for each of the articles and see if they're what you're looking for.
The first answers the following question:
Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. Also, have it resize larger or smaller as the browser window changes. Also, make sure it retains its ratio (doesn't stretch weird). Also, doesn't cause scrollbars, just cuts off vertically if it needs to. Also, comes in on the page as an inline tag.
The second post's goal is to get the following, a "background image on a website that covers the entire browser window at all times. "
Hope this helps.
Just add this one line:
.your-class {
height: 100vh;
}
vh is viewport height.
This will automatically scale to fit the device' browser window.
Check more here: Make div 100% height of browser window
body{
background-image: url(../url/imageName.jpg);
background-attachment: fixed;
background-size: auto 100%;
background-position: center;
}
Try this,
element.style {
background: rgba(0, 0, 0, 0) url("img/shopping_bgImg.jpg") no-repeat scroll center center / cover;
}
I had the same issue, unable to resize the image when adjusting browser dimensions.
Bad Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
}
Good Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
background-size: contain;
}
The key here is the addition of this element -> background-size: contain;
Here's what worked for me:
background-size: auto 100%;
width: 100%;
height: 100vh;
background: url("../img/hero-bg.jpg") top center;
background-size: cover;
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
if you set min-height, for example:
min-height: 100vh;
You can use the below code to fit your background easily
body {
background: url(images/background.svg);
min-height: 100vh;
background-repeat: no-repeat;
background-size: cover;
}
Setting background size does not help, the following solution worked for me:
.class {
background-image: url(blablabla.jpg);
/* Add this */
height: auto;
}
It basically crops the image and makes it fit in, background-size: contain/cover still didn't make it fit.
