Can you tell me how to make such a grid?

Question

css

You need to automatically line up the blocks like here.
Those. i do

.article-block
 .article
 .article
 .article
 .article
 .article

I set article-blockdisplay:flex, they will line up as they should.
Example
I'll make the first "article" with the help first-childof setting my own styles, my own size. How do I line up the remaining 4 "articles" using flexbox as shown in the picture. And all this should be in one block .article-block, since it will just fall out there as a list using php. Is it possible? In which direction to dig? Send pliz.
