I want to hide the scrollbar in Firefox Browser so i used the following in css:
scrollbar-width: none;
when i validate the css file in W3C css validator it shows me the following error:
Property scrollbar-width doesn't exist : none
how to fix this error?
According to https://developer.mozilla.org/en-US/docs/Web/CSS/scrollbar-width the Browser support isn't quit there yet.
The validator probably doesn't recognize it for this reason.
EDIT: To learn how to hide the scrollbar for different browsers see w3schools
