Change font size in simple pages - Text field

I tried to change the font size in the text field of a simple page by editing the source code, but with no success. it is giving me only some options like paragraph, heading1, heading2, heading 3, heading4, heading5, heading 6, and preformatted. I want to put my own size, please any help on that?

What did you try to do that didn’t work?

I’ll jump on board here. Short of coding, is there any way that I can include paragraph breaks in the text? No matter how many blank lines I add in the text box, when I go to the page there’s a single block of text.

I too am referring to a simple page.
