CSS force image resize and keep aspect ratio

by

I am working with images, and I ran into a problem with aspect ratios.

<img src="big_image.jpg" width="900" height="600" alt="" />

As you can see, height and width are already specified. I added a CSS rule for images:

img {
  max-width: 500px;
}

But for big_image.jpg, I receive width=500 and height=600. How do I set images to be re-sized, whilst keeping their aspect ratios.

I’ve struggled with this problem quite hard, and eventually arrived at this simple solution:

object-fit: cover;
width: 100%;
height: 250px;

You can adjust the width and height to fit your needs, and the object-fit property will do the cropping for you.

More information about the possible values for the object-fit property and a compatibility table are available here: https://developer.mozilla.org/en-US/docs/Web/CSS/object-fit

Cheers.
