Comment (by cypherpunks):

 There is no slider any more (UI-wise), just 3 options.

 > no such procedure may exist for the @media CSS component

 Why? If it is possible to block browser window size detection, it should
 be possible to make it an option. Or are you saying that what was made
 possible (someone wrote code about it) cannot be unmade or put into
 conditional logic?
