The Grid Element could be upgraded with some additional grid features and capabilities that now have very good browser support, with the exception of native masonry layouts which is still experimental.
Subgrid
Let nested grids or cells inherit track sizing and line names from the parent grid.
Native Masonry / Grid Lanes
A toggle for native grid masonry-style layouts. Still experimental though but nice to keep an eye on.
Named grid lines and grid-template-areas
Visual controls for naming lines and defining areas.
