Whenever web authors work with a grid spanning some area within another grid, the children of the innermost grid are unaware of the outermost grid structure, which could potentially be a disadvantage if authors want those items to be aligned to other descendants of the outermost grid. A "subgrid" is a nested grid container whose row and column definitions are deferred to its parent; with such concept in mind, the problem above is mitigated by inheriting the grid properties and alignment from the spanned grid area in its parent grid.
