CSS Image size, how to fill, but not stretch?

You can use the css property object-fit. ("sets how the content of a replaced element, such as an <img> or <video>, should be resized to fit its container.")

.cover { object-fit: cover; width: 50px; height: 100px; }

See example here

There's a polyfill for IE: https://github.com/anselmh/object-fit

Related: object-position (specifies the alignment of an element's contents within its box.)

If you want to use the image as a CSS background, there is an elegant solution. Simply use cover or contain in the background-size CSS3 property.

.container { width: 150px; height: 100px; background-image: url("http://i.stack.imgur.com/2OrtT.jpg"); background-size: cover; background-repeat: no-repeat; background-position: 50% 50%; }

​

While cover will give you a scaled up image, contain will give you a scaled down image. Both will preserve the pixel aspect ratio.

http://jsfiddle.net/HZ2FT/ (using contain)

This approach has the advantage of being friendly to Retina displays as per Thomas Fuchs' quick guide.

It's worth mentioning that browser support for both attributes excludes IE6-8.

Enhancement on the accepted answer by @afonsoduarte.
in case you are using bootstrap

Providing width:100% on the style. This is helpful if you are using bootstrap and want the image to stretch all the available width. Specifying the height property is optional, You can remove/keep it as you need .cover { object-fit: cover; width: 100%; /*height: 300px; optional, you can remove it, but in my case it was good */ } By the way, there is NO need to provide the height and width attributes on the image element because they will be overridden by the style. so it is enough to write something like this.

The only real way is to have a container around your image and use overflow:hidden:

HTML

<div class="container"><img src="ckk.jpg" /></div>

CSS

.container {
    width: 300px;
    height: 200px;
    display: block;
    position: relative;
    overflow: hidden;
}

.container img {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
}

It's a pain in CSS to do what you want and center the image, there is a quick fix in jquery such as:

var conHeight = $(".container").height();
var imgHeight = $(".container img").height();
var gap = (imgHeight - conHeight) / 2;
$(".container img").css("margin-top", -gap);

CSS solution no JS and no background image:

Method 1 "margin auto" ( IE8+ - NOT FF!):

div{ width:150px; height:100px; position:relative; overflow:hidden; } div img{ position:absolute; top:0; bottom:0; margin: auto; width:100%; }

Original:

Wrapped:

Method 2 "transform" ( IE9+ ):

div{ width:150px; height:100px; position:relative; overflow:hidden; } div img{ position:absolute; width:100%; top: 50%; -ms-transform: translateY(-50%); -webkit-transform: translateY(-50%); transform: translateY(-50%); }

Original:

Wrapped:

http://jsfiddle.net/5xjr05dt/1/

Method 2 can be used to center an image in a fixed width / height container. Both can overflow - and if the image is smaller than the container it will still be centered.

http://jsfiddle.net/5xjr05dt/3/

Method 3 "double wrapper" ( IE8+ - NOT FF! ):

.outer{ width:150px; height:100px; margin: 200px auto; /* just for example */ border: 1px solid red; /* just for example */ /* overflow: hidden; */ /* TURN THIS ON */ position: relative; } .inner { border: 1px solid green; /* just for example */ position: absolute; top: 0; bottom: 0; margin: auto; display: table; left: 50%; } .inner img { display: block; border: 1px solid blue; /* just for example */ position: relative; right: 50%; opacity: .5; /* just for example */ }

http://jsfiddle.net/5xjr05dt/5/

Method 4 "double wrapper AND double image" ( IE8+ ):

.outer{ width:150px; height:100px; margin: 200px auto; /* just for example */ border: 1px solid red; /* just for example */ /* overflow: hidden; */ /* TURN THIS ON */ position: relative; } .inner { border: 1px solid green; /* just for example */ position: absolute; top: 50%; bottom: 0; display: table; left: 50%; } .inner .real_image { display: block; border: 1px solid blue; /* just for example */ position: absolute; bottom: 50%; right: 50%; opacity: .5; /* just for example */ } .inner .placeholder_image{ opacity: 0.1; /* should be 0 */ }

http://jsfiddle.net/5xjr05dt/26/

Method 1 has slightly better support - you have to set the width OR height of image!

With the prefixes method 2 also has decent support ( from ie9 up ) - Method 2 has no support on Opera mini!

Method 3 uses two wrappers - can overflow width AND height.

Method 4 uses a double image ( one as placeholder ) this gives some extra bandwidth overhead, but even better crossbrowser support.

Method 1 and 3 don't seem to work with Firefox

Solution not requiring image as a background and will auto-resize without being cut-off or distorting.

Another solution is to put the image in a container with the desired width and height. Using this method you would not have to set the image as a background image of an element.

Then you can do this with an img tag and just set a max-width and max-height on the element.

CSS:

.imgContainer {
    display: block;
    width: 150px; 
    height: 100px;
}

.imgContainer img {
    max-width: 100%;
    max-height: 100%;
}

HTML:

<div class='imgContainer'>
    <img src='imagesrc.jpg' />
</div>

Now when you change the size of the container the image will automatically grow as large as it can without going outside the bounds or distorting.

If you want to center the image vertically and horizontally you can change the container css to:

.imgContainer {
    display: table-cell;
    width: 150px; 
    height: 100px;
    text-align: center;
    vertical-align: middle;
}

Here is a JS Fiddle http://jsfiddle.net/9kUYC/2/

Not using css background

Only 1 div to clip it

Resized to minimum width than keep correct aspect ratio

Crop from center (vertically and horizontally, you can adjust that with the top, lef & transform)

Be careful if you're using a theme or something, they'll often declare img max-width at 100%. You got to make none. Test it out :)

https://jsfiddle.net/o63u8sh4/

<p>Original:</p>
<img src="http://i.stack.imgur.com/2OrtT.jpg" alt="image"/>

<p>Wrapped:</p>
<div>
    <img src="http://i.stack.imgur.com/2OrtT.jpg" alt="image"/>
</div>


div{
  width:150px; 
  height:100px; 
  position:relative;
  overflow:hidden;
}
div img{
  min-width:100%;
  min-height:100%;
  height:auto;
  position:relative;
  top:50%;
  left:50%;
  transform:translateY(-50%) translateX(-50%);
}

Building off of @Dominic Green's answer using jQuery, here is a solution that should work for images that are either wider than they are high or higher than they are wide.

http://jsfiddle.net/grZLR/4/

There is probably a more elegant way of doing the JavaScript, but this does work.

function myTest() {
  var imgH = $("#my-img").height();
  var imgW = $("#my-img").width();
  if(imgW > imgH) {
    $(".container img").css("height", "100%");
    var conWidth = $(".container").width();
    var imgWidth = $(".container img").width();
    var gap = (imgWidth - conWidth)/2;
    $(".container img").css("margin-left", -gap);
  } else {
    $(".container img").css("width", "100%");
    var conHeight = $(".container").height();
    var imgHeight = $(".container img").height();
    var gap = (imgHeight - conHeight)/2;
    $(".container img").css("margin-top", -gap);
  }
}
myTest();

I helped build a jQuery plugin called Fillmore, which handles the background-size: cover in browsers that support it, and has a shim for those that don't. Give it a look!

---

This will Fill images to a specific size, without stretching it or without cropping it

img{
    width:150px;  //your requirement size
    height:100px; //your requirement size

/*Scale down will take the necessary specified space that is 150px x 100px without stretching the image*/
    object-fit:scale-down;
}

---

after reading StackOverflow answers the simple solution I got is

.profilePosts div {

background: url("xyz");
background-size: contain;
background-repeat: no-repeat;
width: x;
height: y;

}

---

Try something like this: http://jsfiddle.net/D7E3E/4/

Using a container with overflow: hidden

EDIT: @Dominic Green beat me.

I think it's quite late for this answer. Anyway hope this will help somebody in the future. I faced the problem positioning the cards in angular. There are cards displayed for array of events. If image width of the event is big for card, the image should be shown by cropping from two sides and height of 100 %. If image height is long, images' bottom part is cropped and width is 100 %. Here is my pure css solution for this:

https://i.stack.imgur.com/cNPxd.png

HTML:

 <span class="block clear img-card b-b b-light text-center" [ngStyle]="{'background-image' : 'url('+event.image+')'}"></span>

CSS

.img-card {
background-repeat: no-repeat;
background-size: cover;
background-position: 50% 50%;
width: 100%;
overflow: hidden;
}

---

you can do it by 'flex' display. for me!:

.avatar-img { display: flex; justify-content: center; align-items: stretch; border-radius: 50%; border: 1px solid #dee2e6; height: 5.5rem; width: 5.5rem; overflow: hidden; } .avatar-img > img { flex-grow: 1; object-fit: cover; }

---

To fit image in fullscreen try this:

background-repeat: round;

---

<div class="container">
     <img src="http://i.stack.imgur.com/2OrtT.jpg"/>
</div>

<style>
.container {
       width: 150px;
       height: 100px;
       overflow: hidden;
}
</style>

---

As far as I know, there is a plugin to make this simple.

jQuery Plugin: Auto transform <img> into background style

<img class="fill" src="image.jpg" alt="Fill Image"></img>

<script>
    $("img.fill").img2bg();
</script>

Besides, this way also fulfills the accessibility needs. As this plugin will NOT remove your tag from your codes, the screen reader still tells you the ALT text instead of skipping it.

---

you have to use background-size : cover in the css

js code

 <div>
   <div className={styles.banner}>banner</div>
 </div>

css code

.banner{
  background: 
    url("./images/home-bg.jpg");
  background-size: cover;
  height: 53rem;
  width: 100%;
}

object fit is not working

background-size: contain is also not working
