When text is entered on a page, a box is formed around the text. This box forms a container for that particular bit of text. Each box is like an island on the page that can be individually moved and reshaped.
It's also possible to pull out one line of text and move that to a different place or add it to another piece of text. You'll try this in the practice session.
