Has anyone encountered abnormal effects of css border inset and outset under the new version of IE?_html/css_WEB-ITnose

An old page, I suddenly discovered during a recent visit that the inset and outset have turned into gray borders. I created a new test page with only one DIV style "border-top-style: inset; border-right" "-style: inset; border-left-style: inset; border-bottom-style: inset" still displays abnormally in IE.
Is this style canceled in the new version of IE? Have any other friends encountered this?

I found the place that should be modified
Now under IE, you must add the border COLOR after inset and Embedding outset can be effective. Older versions of IE don't seem to need to specify the border color, so pages written before will not run properly with current browsers.
