How to make the same adaptive gallery?

Question

css

Good afternoon, tell me how to implement the same adaptive gallery as here *tyk* . In the Featured Works block. The site, apparently, is written on the constructor, so it is difficult with the code there. The question is how to make the same smooth adaptability on each browser window size reduction

In your example, done here on this: link .
This can be repeated on pure flex + media queries and even without flex on css, but there will be a little more code.
