CSS for Cropping Images

I've been struggling with how to display images of various sizes in the same size. You can adjust the height and width of the image, or the max-height and max-width, but those will skew the aspect ratio.

To date, I'd been addressing this by putting the image in a sized div, and hiding the image that was outside the div, but this causes issues with positioning - you have to position the image the way you want it in the div - so the image is always cropped on top or on bottom, and not centered.

I just found a simple CSS solution to this:

img {
    object-fit: cover;
}

This will center and crop the image to a size specified by the image tag.
