Today I encountered a very strange li a click problem. _html/css_WEB-ITnose

... Well, today I was going to make a pop-up window.

The task assigned to me by the background php is very simple for me because it is very simple for me to do this. I have done it no less than three times. The key is to know the principle of pop-up windows.

Click .youkeli to pop up .youkelogin, click .close1 in the pop-up window to close the pop-up window and return to the page.

Of course the problem I am talking about is not here, but that I gave youkeli to li. As a result, when I clicked the close button, I couldn't close it and kept switching between black and non-black screens. I was speechless.

After trying for a long time, I finally found the reason, so I added the .youkeli class to A. The result was successful and can be closed.

I originally wanted to find an expert to solve it, but later I found out the reason myself.

The summary is that the click effect of li is always so bad. In addition, the href should be ###, a dead link, not #, which jumps to the top, so this is also a detail.
