Add classes ExplicitTrackSizing and MetaGridTrackSize which will allow for managing properties like auto-fill and minmax. In the following CSS example there are 3 classes that will be used: grid-template-column: repeat(auto-fill, minmax(50px, 1fr) 75px); ExplicitTrackSizing - will contain the entire value. e.g. repeat(auto-fill, minmax(50px, 1fr) 75px) With a flag if it's a repeat, as well as references to the MetaGridTrackSizes which is the next step down. MetaGridTrackSize: Contain the individual grid track sizes. Here there are two: minmax(50px, 1fr) as well as 75px. This way can keep track if it's a minmax function or not, and the references to both GridTrackSizes in the case it is, or in just the one if it is not. GridTrackSize: Is the most basic element, in this case there are three in total; two of which are held by the first MetaGridTrackSize, and the third is held by the second MetaGridTrackSize. Examples: 50px, 1fr and 75px.
