Isn't there a regular text editor to bold/italics/whatever to font without having to use custom CSS? I thought for sure there used to be. I did bold something with a key stroke, but it doesn't hold once I click off of the field.

On which form are you working? Which text do you want to change?

You can bold/italics field labels on the Card Forms.

This can't be done on the Classic Forms. Also, please note that Card Forms can't be customized with CSS.

The Paragraph field can be customized in both layouts.
