CSS Specificity Calculator
Calculate, compare, and validate CSS selector specificity weights using W3C standards.
Tailwind Excellence Prover
AI agents build bloated styling layers containing arbitrary values, div-only layouts, inaccessible contrast, and legacy configurations. This prover enforces strict design token structures (@theme), utility-first compliance, semantic HTML, mobile-first layouts, and interactive focus states.
Room Proportion Checker
Checks if a room's dimensions meet ergonomic and architectural standards for visual harmony.
Design Prover
Every AI frontend looks identical: hero, 3 cards, 3 cards, CTA, rounded-xl, shadow-lg, blue/gray/white. Design Prover forces the agent to prove its design has dramatic hierarchy, unpredictable layout, intentional whitespace, commanding typography, and color with actual personality.

Before you connect
Questions about CSS Grid Validator.
The practical details behind the request, access and result.
How can I use CSS Grid Template Area Validator to fix my layouts?
You pass your grid-template-areas string to the MCP, and it will identify any rows that don't match or areas that aren't rectangular.
Does CSS Grid Template Area Validator work with Claude or Cursor?
Yes, you can connect this MCP to any compatible client like Claude, Cursor, or Windsurf to validate your CSS code instantly.
Can the CSS Grid Template Area Validator find holes in my grid?
Yes, it specifically checks for gaps within your named areas to ensure every part of your layout is a solid rectangle.
Will CSS Grid Template Area Validator catch column mismatches?
It will. It compares the number of columns in each row and flags any discrepancies immediately.
Is this MCP useful for automated UI testing?
Absolutely. You can use it to verify that CSS generated by your agents meets structural requirements before it is ever applied to a component.
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` capability work?
The validate_grid_template_area capability 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.
