CSS subgrid is a feature in CSS Grid Level 2 that allows nested grids to inherit the track sizing of their parent grid for consistent layouts.
It eliminates the need for manual coordination of column and row sizes, simplifying layout creation.
CSS subgrid offers benefits like alignment consistency, simplified code, responsive design support, and flexibility for complex layouts.
As of June 2025, CSS subgrid is supported in major modern browsers, offering improved layout capabilities.
To use subgrid, define a parent grid container and a nested grid, setting grid-template-columns and grid-template-rows to 'subgrid' for inheritance.
Example code snippets demonstrate setting up subgrid for card layouts and nested form layouts for aligned designs.
Tips for effective use include using subgrid judiciously, combining with other grid features, providing fallbacks for older browsers, testing responsiveness, and debugging layouts.
Common pitfalls include ensuring the parent element is a grid container, correct span values for nested grid items, and setting explicit gap on nested grids if needed.
CSS subgrid streamlines layout creation, offering a powerful tool for responsive and visually appealing designs with minimal manual effort.
Experiment with examples, combine subgrid with other features, and explore real-world scenarios to leverage the full potential of CSS subgrid.
