The "grid" is a graphic design principle [1] that existed long before CSS. You can implement this in CSS with flexbox or something else. If you don't care about vertical alignment of elements at different heights on your page then you probably don't need a grid framework.

I'm familiar with grids as a design profile. My point was that most 'grid system' libraries add no value and make some things worse.
