Grids for web layouts with no gutters: simpler, more practical and more flexible (ilyabirman.net)

Yep! This is the main reason I use a hand-rolled grid and not one of the many common/popular ones.

I am not a CSS expert, but I would think there must be a reason frameworks like Bootstrap went with the gutter approach? I don't know what it is, but I suspect there is a reason because otherwise this is so much simpler to deal with.
