Does anyone know if it's possible to change the cursor appearance with CSS?
It is probably likely through coding, although it is dependent on whether Wix will support it through tracking and analytics or with code on everypage as you won't be able to use the site code tab. However you'll have to research and find that out yourself.
Wix does not allow access to the DOM so this is not possible.
Feel free to post a Feature Request.
@Yisrael (Wix) , will it ever be possible to access the DOM, or will we always need to wait for Wix to release every single feature separately?
Difficult to say. Prohibiting access to the DOM prevents the user from breaking things - and therefore makes life much easier for support personnel. 😊 It also makes life easier for the site owner.
Perhaps "gated" access to the DOM could be provided if the technical issues and difficulties could be properly addressed.
