Using positioning I have used positioning. The key is that after the above div is pulled down, the contents of the two divs overlap. Is it possible to make the drop-down div float on top of it? http://www.m1905.com/ is like the upper left corner of this website.

Your positioning is useless, right? To make the drop-down div float on top, you need to use positioning. First relative positioning, then absolute positioning. Don’t forget to add the z-index attribute there for absolute positioning. There are many related special effects online. You can also learn how to use positioning

I defined it casually and did not write standardized css for you. It is useless under IE6 because IE6 does not support the fixed attribute. If you want to support IE6, simple CSS can no longer achieve it.
