What does it mean if the validation fails?

A failure means your grid has either inconsistent column counts between rows or a named area that is not a perfect rectangle.

How does the `validate_grid_template_area` tool work?

The `validate_grid_template_area` tool parses your string by newlines and spaces, then performs a deterministic 2D array traversal to check for structural integrity.

Can I use the period symbol in my template string?

Yes, the period `.` represents an empty cell and is a valid part of your grid structure.

The CSS Grid Template Area Validator ensures that your grid-template-areas strings are structurally sound. It checks for consistent column counts across all rows and verifies that every named area forms a perfect, solid rectangle without holes or irregular shapes. This prevents broken layouts in UI-generating agents.
