如何控制html中的`div`重叠 [英] How to control `div` overlapping in html

问题描述

我正在创建一个网页，并且我有两个div，例如A和B. A的位置为fixed且位于页面顶部，而B的位置为absolute且位于页面中间.当它们重叠时，B排在A的顶部，但是我希望这可以反过来.我希望A胜于一切，但我不知道该怎么做.

I am creating a webpage, And I have two divs, A and B for instance. A's position is fixed and it's on top of the page, but B's position is absolute and is somewhere in the middle of the page. When they Overlap, B comes on top of A, But I want this to be the other way around. I want A to come on top of anything, but I don't know how to do that.

请注意，更改其位置不是一种选择.

Please note that changing their positioning is not an option.

先谢谢您. :)
