You can change their design in Layout Mode, or connect the elements to other content––display a post date instead of an author for example. You can also change them for each post. You must have a post title, but you can choose to have no author or different authors and each post can have a unique background image.
To connect a text widget to the title or author:
- Right click the widget to open the context menu.
- Select Connect to Data.
- Choose a connection.
