Tablet and Mobile Support


I'm trying to find any guide or support for instructions when it comes to adjusting the site for tablet/mobile view. And so far under the support forum, there's limited discussion about this -- rather, I'm looking for instructions.

Right now, I'm facing issues of trying to resize the text within the header or any sections. I've trying to apply "font-size: 10px" in CSS but no luck.

Any help would be great.
