Do Japanese and Korean operating systems display the same style differently? _html/css_WEB-ITnose

Hello, as mentioned, why is this? It seems that some styles such as width: 33% and position: fixed are normal under the Chinese system, but there are problems under the Japanese and Korean operating systems. I can’t find such a document anymore on Google. Damn it, who knew? What's the difference between these?

Are the IE versions consistent?
In addition, the lengths occupied by Korean and Japanese are different. Does this affect the length of space occupied during parsing?

It is estimated that the default style of each browser is different
