  1. Open your project in Codex.
  2. Copy and paste the prompt below.
  3. Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/thedaviddias/Front-End-Checklist/blob/HEAD/skills/css-grid/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/css-grid, but wait for my approval before writing files or running scripts.

Use CSS Grid for two-dimensional layouts

CSS Grid solves layout problems that previously required JavaScript or complex CSS hacks — aligning items across both axes simultaneously, creating named layout areas, and building responsive grids that adapt to content. Using Flexbox for two-dimensional layouts results in workarounds like fixed widths that break responsiveness.

Quick Reference

  • Use Grid for two-dimensional layouts (rows AND columns); use Flexbox for one-dimensional
  • grid-template-areas provides a visual representation of the layout in your CSS
  • minmax() and auto-fill/auto-fit create responsive grids without media queries
  • Subgrid allows nested elements to align to the parent grid's tracks

Check

Look for float-based or Flexbox layouts in this CSS that are trying to control both rows and columns — they may be better implemented with CSS Grid.

Fix

Convert this two-dimensional layout to use CSS Grid with appropriate grid-template-columns, grid-template-rows, and grid-template-areas.

Explain

Explain CSS Grid fundamentals: tracks, cells, areas, fr units, minmax, and auto-fill vs auto-fit.

Code Review

Review stylesheets, component styles, and responsive states related to Use CSS Grid for two-dimensional layouts. Flag exact selectors, declarations, or breakpoints that violate the rule in the rendered UI.
