Under normal circumstances, the div and Div measured between 12 is set 12 is good, but this is floating, floating margin does not merge, will be superimposed, so the overlay is 12px, then each blue div margin is set to 6px;
Also measures the red background border according to the nearest blue div distance is 18px =6+12;
So set the outer div padding:12px
Closed float I set the overflow:hidden here with the parent element.
For reference: Those years we cleaned up the float
