CSS: 100% width or height while keeping aspect ratio?

Question

Currently, with STYLE, I can use width: 100% and auto on the height (or vice versa), but I still can\'t constrain the image into a specific positio

Answer 1

Simple solution:

min-height: 100%;
min-width: 100%;
width: auto;
height: auto;
margin: 0;
padding: 0;

By the way, if you want to center it in a parent div container, you can add those css properties:

position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);

It should really work as expected :)
