The content in the html head tag is displayed in the body_html/css_WEB-ITnose

Today the boss said that the homepage of a website displays abnormally under IE. Looking at the code, I found that all the elements in the head have gone to the body, and the first line of the body begins with a pair of double quotes. Wendu Niang said it was an encoding problem. Many people said it was because the file was encoded in the utf-8 BOM format, so she used Notepad to create a new file and then encoded it in the utf8 BOM-free format and saved it, overwriting the saved file. file, ok, problem solved.
