I posted this question on the page layout forum, but did not get any
answers. I hope someone can answer me here.

Hi!
Can I use relative font size in herited styles?
What I mean is that I would like to create a template that for example has a
"body text" of Arial, 12 points... I would like to define a "large body
text" style which is based on the "body text" but the font size is let's say
10% larger or just say "large", and other styles that are based on body
style. Now if I change the font size of the base style, which is "body
text", I don't have to worry about the other styles that are based on "body
text", because they will change automatically as well.

Is it possible to do this in Word?
