In one WordPress.com blog, when I write a post, I see small print onscreen. In another blog, I see large print onscreen. How can I change the size of the print I see? Note: this is not a question about how to change the size of the print that appears in the resulting blog post. I am not asking about HTML. I am asking about something that, I am guessing, is set by the theme I have chosen. Thanks!
The blog I need help with is raywoodcock.wordpress.com.
