TABS editing / responsiveness : Floating Region on tablet and phone

Hi there

1-How can I have text displayed in a responsive way in tabs.

I copied the tabs-panino preset CSS to my theme ( called it pricetabs in my theme COIFFURE A DOMICILE ) but it does not display text in a responsive way on a mobile . Is the anything I forgot to do ?

2- I am experimenting floating region … It displays only on desktop ! can I get it on tablet and mobile ? I did not see a show icon in responsive mode !

3- can you confirm that theupfront slider element is NOT responsive and truncate images … ( do you know of any responsive slider I could use instead )

4- Is there a way to hide a region when in Desktop Mode ?

Thanks have a nice day
