In Firefox and IE browsers, div display is abnormal or the location of margin and position is abnormal.

If you are a website friend, you may encounter problems in my questions. You need to worry too much. Let me talk about my practices. Very simple.

We recommend that you use Firefox to test the webpage compatibility. After all the settings are completed, we will start the following steps on the premise that Your webpage is completed on Firefox, and it is compatible. In addition, sogou browser is also the IE kernel, and some ul-li and span may have different lengths. In this case, simply change the length.
First, place the following statement at the top of the page, and then the downstream statement will not work. Some other Div definitions may fail. In this case, you only need to add the position to absolute on the expected Div or parent Div. Of course, if not, leave a message for me. Thank you.
