Hello,

I'm kinda new to web-developing and I've searched my way here for some help regarding css and boxes. I found a picture with a basis I'd like to start working with, but I have no clue how to code those actual boxes in css to make them line up as I wish.

Here's a picture that I'd like my website's boxes to look like.

Any help is appreciated, thanks!
