Inappropriate paragraph in grid system documentation's "How it works" section ("Sounds good?")

Created by: Chealer

The documentation's first section on the Grid system asks "Sounds good?".

As pointed out in issue #23754 (closed) , "sounds not so good", so assuming a positive answer with "Great, let’s move on to seeing all that in an example." is pretentious at this time. In any case, it would be preferable to avoid unnecessarily questioning the reader. Since the paragraph is not immediately followed by examples, I would suggest to just remove it, or to fix and move down.
