/*
I'm playing with flexbox to build a future proof fluid and responsive grid system.
Flexbox is AWESOME on this task because it do every single thing a grid user need:
- fluid columns with fluid gutters;
- fluid columns with fixed gutters;
- fixed columns with fluid gutters;
- fixed columns and fluid columns on the same row;
- nested grids with or without side gutters;
- centered columns;
- centered nested grids with or without side gutters;
- equal heights of columns on the same row;
- responsive layouts with media queries changing only the flex-basis property.
While building a solid system and a generator tool (I'm developing an inline-block grid generator tool) I'm playing here.
