How do I fit an image (img) inside a div and keep the aspect ratio?

Question

I have a 48x48 div and inside it there is an img element, I want to fit it into the div without losing any part, in the mean time the ratio is kept, is it achievable using h

Answer 1

Unfortunately max-width + max-height do not fully cover my task... So I have found another solution:

To save the Image ratio while scaling you also can use object-fit CSS3 propperty.

Useful article: Control image aspect ratios with CSS3

img {
    width: 100%; /* or any custom size */
    height: 100%; 
    object-fit: contain;
}
