Weird div margins, terrible unsolvable problem, sincerely looking for answers_html/css_WEB-ITnose
As shown in the picture above, the blue part is the background floating div, and the white part in the middle is the centered div. No margins are set.
My question is: Why are there margins above and below the white div part?
It’s so difficult to understand.

Post the code and you won’t be able to tell anything by looking at it this way.
