But set


The page is still messy when opening, and it is not executed in IE8 mode. What is the reason?

Pay attention to the inside This sentence: IE=EmulateIE8: Follow the DOCTYP mode.
This means that we also need to look at the doctype mode.
According to your intention here, it is mandatory. This should be used: IE=8
