If it is just static text than you can create a page and use text widget and associate this page in your navigation. if you want to change the UI of that page than you can do that either by adding inline style or update the CSS or Sass according to your requirements.
Hope this helps!
Perhaps the rich text widget would meet your needs. It can be used to input rich text with formatting, it can also used to render it later.

I am not sure how you are trying to achieve this. Please can you share what you trying to do in bit more detail as a comment or by editing / updating your question?
I tried both the Apps but I am not sure how to add content as that field is frozen
