Which gives
So is it possible that the "Box 4" go under the Box 1 and fill the space left, and if there was a Box 5 go under Box 2, etc... ? Just like Tetris :D
EDIT
Please note that there will be alot more boxes, not just 4 or 5, so I need a CSS solitions that everytime I call that class, it will imbricate it.
EDIT 2
Ok now using Masonry.js, it's they way I want to why their's so much space in the position top on each other. Look a the image. I need them much closer to each other like they show on their website.
I'm using this function
$('#equipe').masonry({
itemSelector: '.equipeBox'
});

Answer 1

Check out Masonary.js or this tutorial here.

Answer 2

try floating box 3 to right, the rest to left, or putting box 1 and 4 in a wrapper

Answer 3

According to the tetris rule, this layout is actually the best since box 3 is less high than box 1....
