Since this is only ever called with fixed TrackSizeComputationPhase values you could make it a template argument instead. Maybe not very important.

The functions that this method is resolving are not the ones passed as arguments but the minimum size and maximum size functions specified by authors when defining the grid, so I think the name is still accurate. > Since this is only ever called with fixed TrackSizeComputationPhase values > you could make it a template argument instead. Maybe not very important. Sure, I actually also had the same idea after uploading the patch.

Use of enum classes is not actually that important as these enums are not used outside the class. TrackSizeComputationPhase and DistributeSpacePhase probably don't need to be public (unless you plan to use them somewhere else too).

Agreed, I'm right now changing the functions to have a template parameter, something like: template <RenderGrid::TrackSizeComputationPhase phase> void RenderGrid::resolveContentBasedTrackSizingFunctionsForItems(GridTrackSizingDirection, GridSizingData&, const GridItemsSpanGroupRange&) which gives us a nice set of calls: resolveContentBasedTrackSizingFunctionsForItems<ResolveIntrinsicMinimums>(direction, sizingData, spanGroupRange); resolveContentBasedTrackSizingFunctionsForItems<ResolveMaxContentMinimums>(direction, sizingData, spanGroupRange); resolveContentBasedTrackSizingFunctionsForItems<ResolveIntrinsicMaximums>(direction, sizingData, spanGroupRange); resolveContentBasedTrackSizingFunctionsForItems<ResolveMaxContentMaximums>(direction, sizingData, spanGroupRange);
