The CSS Working Group has published a Candidate Recommendation of CSS Grid Layout Module Level 2 and an updated Candidate Recommendation of CSS Grid Layout Module Level 1. This CSS module defines a two-dimensional grid-based layout system, optimized for user interface design. In the grid layout model, the children of a grid container can be positioned into arbitrary slots in a predefined flexible or fixed-size layout grid. Level 2 expands Grid by adding “subgrid” capabilities for nested grids to participate in the sizing of their parent grids. Comments are welcome by 18 October 2020.
