BRAND NEW LAYOUTS WITH CSS SUBGRID

Summary from the TLDR Dev newsletter

CSS Subgrid allows developers to extend CSS Grid layouts through the DOM tree, enabling new UI possibilities and better semantic markup. It allows nested elements to participate in the parent grid, solving issues with nested layouts and sibling responsiveness. Devs can use `grid-template-rows: subgrid` and `grid-template-columns: subgrid` to inherit the grid template.
