You can scale font size separately for each view without touching the actual underlying style. So instead of changing 12pt to 16pt, just change text scaling setting for that particular view from 100% to 130%. It is in the Home tab of every view except Desktop.
Yes, but instead of me having to go into every page for each device type and setting the font size appropriately (and then having to go into every page for every device type should the client change their mind) why can’t we have a “five-part” style in which we can set the size for each device type?
It’s not so different from what I do with media queries in CSS currently (when I hand code).
