Tip: You don’t have to modify every paragraph style in the template; for example, for a simple letter or document, you may want to modify only the body text style and a heading style.
In the Font section, choose a font and font size for the paragraph style you selected.
You can also use other controls in the Font section to choose character styles like bold and italic, and change the text color.
Tap the Update button that appears next to the paragraph style.
The default style is updated with your changes. You can Add and replace text in Pages on iPad
