How to implement blocks with scalable images on bootstrap?

Question

Bootstrap

I am getting acquainted with bootstrap little by little, I did not know how to formulate the question correctly, in general I wanted to make something like blocks, with images that also scale depending on the width of the display. For example, like the section "Our work" on flatata.com
Would be tips on how to implement this.

Answer 1

if we are talking about bootstrap 3, then there is a special class for scaling .img-responsive images

Answer 2

img { max-height: 100%; }
Blocks are scaled from the screen size and images take max. block width. To do this, you just need to use bootstrap's rubber blocks.
