Setting fontSize of Textarea (bootstrap) at design time

Is there any way of setting a bootstrap textarea’s fontsize at design time. Changing the fontSize on the design form just seems to change the Header size and not the text within the textarea. I know I can change it at runtime using Textarea_contents.style.fontSize = “30px”, but is there any way of doing this at design time?

Not at this time. It’s something we should look at, though.
