This is something where the penny just will not drop for me: altering the text size in a variant.

What method can I use to edit the text size without it altering the other variants but maintain the sharing? As an example, I would like the text to say Hello World at size 18 on the mobile site and size 16 on the main site but still be able to alter the colour/spelling etc and have it reflect on both variants.

Ideally I would like to simply grab the diagonal selection handles an resize the sucker as I would an image. A while ago, boy advised me to look into Styles, which, while I learned a lot, made me rock back and forth in a corner and sob quietly.

I am determined to get comfortable with this as I can't afford to keep replacing smashed keyboards.
