Suggestion for a CSS exercise

This is related to exercise at https://www.freecodecamp.org/learn/responsive-web-design/applied-visual-design/push-elements-left-or-right-with-the-float-property

This follows the exercise on ‘absolute’ and ‘fixed’ properties.
However, float differs from them in a major way, where other elements wrap around the floated elements. This is neither evident from exercise, nor mentioned in the text.

I would suggest expanding a bit more on this in the exercise or text.
