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

Question

I have an image, and I want to set it a specific width and height (in pixels)

But If I set width and height using css (width:150px; height:100px), image will be stretched, and It may be ugly.

How to Fill images to a specific size using CSS, and not stretching it?

Example of fill and stretching image:

Original Image:

Stretched Image:

Filled Image:

Please note that in the Filled image example above: first, image is resized to 150x255 (maintained aspect ratio), and then, it cropped to 150x100.

Answer 1

You can use the css property object-fit.

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

<img src="http://i.stack.imgur.com/2OrtT.jpg" class="cover" width="242" height="363" />
