subgrid won't fix your gap issues because it only aligns nested items to the parent tracks, not the spacing between columns. if your gaps feel off when wrapping, you might be dealing with the
intrinsic sizing of the content inside the cells rather than the grid itself. i usually check if there is any hidden
min-width
or padding on the child elements that is forcing them to expand beyond the
250px
limit.
it's almost always a margin issue on the children . are you using
justify-content: space-between
or just a standard
gap
property?
