People often use pop-up layers when writing div css. Due to a bug in IE6, when multiple tags are used to repeatedly write pop-up layers, the subsequent layers will be laminated on top of the pop-up layer. This problem occurs in Firefox.

The principle is as follows: Use Jquery to increase the z-axis of the pop-up layer in sequence. Highly. The code is very simple and the effect is very significant. Hoho!
