Contain an image within a div?

Question

I want to contain an image into a 250 x 250 div, forcing the image to resize but not stretch. How can I do this? By the way, the image will usually be bigger than the div itself, which is why resizing comes into the picture.

<div id = "container">   <img src = "whatever" /> </div>  #container { width:250px; height:250px; border:1px solid #000; } 

Here's a jsfiddle which someone can edit:

Answer 1

object-fit, behaves like background-size, solving the issue of scaling images up and down to fit.

The object-fit CSS property specifies how the contents of a replaced element should be fitted to the box established by its used height and width.

https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit

.cover img {     width: 100%;     height: 100%;     object-fit: cover;     overflow: hidden; }

Browser Support

There's no IE support, and support in Edge begins at v16, only for img element: https://caniuse.com/#search=object-fit

The bfred-it/object-fit-images polyfill works very well for me in IE11, tested on Browserstack: demo.

Alternative without polyfill using an image in SVG

For Edge pre v16, and ie9, ie10, ie11:

You can crop and scale any image using CSS object-fit and object-position. However, these properties are only supported in the latest version of MS Edge as well as all other modern browsers.

If you need to crop and scale an image in Internet Explorer and provide support back to IE9, you can do that by wrapping the image in an <svg>, and using the viewBox and preserveAspectRatio attributes to do what object-fit and object-position do.

(The author explains the technique thoroughly, and duplicating the detail here would be impractical.)

Answer 2

Use max width and max height. It will keep the aspect ratio

#container img  {  max-width: 250px;  max-height: 250px; }
