Blocks of different widths?

Question

PHP

Hello. Tell me how such logic can be implemented in rails, or rather block calculation.
For example, there are blocks equal in width and height (picture below)
Everything is ok.

Further, for example, 1 becomes equal in width to two small ones

. But when, when adding one more, for example, a small one, this large one goes down accordingly.

At the same time, 3 small and an empty block remain on top. How do others do it? How do they get so that with such a mixture at the top there are 4 blocks and not 3?
A vivid example of where this is normal is the site www.the-village.ru
Please tell me how they do it? Somehow they calculate how many blocks in width or what?
I will be very grateful for advice.
