grid-lanes-subgrid-001a.html The 4c was placed below 4a instead of 4b, because the item-tolerance property defaults to 16px. Changing to 0px will correctly set it below 4b. grid-lanes-subgrid-002a.html Heights were off because they were not being properly set. They are set by the grid-template-rows in the -ref case. Needed to force item 4b to span across 2, because it is participating in the grid.
