Really? When I first heard about Bootstrap I found it pretty easy to look at almost all of the documentation in under an hour, and it covered all of these things, except the hover dropdown, which is simple css, and the media queries.
From the first bullet point in the "Grid System":
>Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
I guess you might not think to look for it in the documentation, but if you don't think to look for it, that means you probably aren't using it, and don't need it... I still wouldn't really call any of these things tips or tricks, it's just actually reading the documentation of what framework you're using, which apparently people don't do?
