Quaff provides a responsive 12-column CSS grid. Use row for the
container and col-* for its children. For flex layouts,
alignment, sizing, and spacing, see CSS helpers.
You can add space between your columns using the q-gutter-* classes, where * is either xs, sm, md, lg, xl or none. Use q-gutter-x-* or q-gutter-y-* when spacing should only apply in one axis. The q-col-gutter-* names are supported as compatibility aliases for row
grids.
The following example uses q-col-gutter-x-md with q-col-gutter-y-sm:
Grid classes use the MD3 window sizes below, matching Quaff.screen. See adaptive layouts for navigation and
list/detail examples.
