The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "how to solve the problem of absolute positioning elements being obscured"!

The specific methods are as follows:

Under ie7

Absolute positioning element even if the z-index value is high, if the parent element whose relative positioning is set does not set the z-index value, it is possible (of course, when the layout is masked) that it will be obscured by the element that sets the relative positioning later (even if the later relative positioning element does not set the z-index value).

The code is as follows:

If the upper and lower div cover each other, then the lower div will cover the upper div

The solution is as follows:

Sets the z-index value for the element with relative positioning set for the obscured absolute positioning element

The code is as follows:
