是否可以仅在浮动 div 之间创建边距,而 parent 两侧没有边距。
所以基本上:
no margin <div> |margin| <div> |margin| <div> |margin| <div> no margin
no margin <div> |margin| <div> |margin| <div> |margin| <div> no margin
no margin <div> |margin| <div> |margin| <div> |margin| <div> no margin
no margin <div> |margin| <div> |margin| <div> |margin| <div> no margin
no margin <div> |margin| <div> |margin| <div> |margin| <div> no margin
像那样。
