Motion graphics 15 with the three dots on either side. how can I tell which ones will allow font size change- Just try them?
I don't have Motion Graphics 015 title, but from what I've seen, so much of CL template offerings always have massive restrictions when it comes to just basic customizations. Basically, you only have the controls they expose to you, which in this case is not font size.
In your OP you said you "change the size of text", just how did you do that? As mentioned prior, you can scale everything but I see no way through the exposed controls that you have to change font size, just other attributes of the template text blocks.
