scrollbar-width: none;
I just encountered this problem in the project and tried it at random. You can try
(compatibility is not guaranteed, my version is FF64)


/ Google hides /
:-webkit-scrollbar {display:none}
html {
/ hide scroll bars. When IE overflows, you can still scroll /
overflow:-moz-scrollbars-none; under Firefox
}


as above, it is recommended that the auto-completion prefix tool be introduced into the project, so that there is no need to consider every attribute that needs to be compatible with a prefix.
