## Description

Writing complex CSS Grid layouts is a headache, especially when you're relying on an AI client to generate the code for you. One small typo in a template-area string and your entire layout collapses into a mess of overlapping elements or empty gaps. This MCP acts as a safety net for your frontend workflow. You can pass any grid string to it, and it will immediately tell you if your rows are uneven or if an area isn't a perfect rectangle. It's like having a senior developer double-checking your CSS structure in real time. Since Vinkius manages this tool, you just connect your preferred client and start validating layouts instantly without any manual setup. You stop guessing why a layout looks broken and start knowing it's correct.

## Tools

### validate_grid_template_area
Checks if your CSS Grid Template Area string is structurally sound and rectangular. It identifies mismatched columns or irregular shapes immediately.

## Prompt Examples

**Prompt:** 
```
Is this CSS grid area string valid: "header header\nsidebar main"?
```

**Response:** 
```
The validation result shows the grid is valid with 2 columns and 2 rows.
```

**Prompt:** 
```
Check this template: "a b\nc d e"
```

**Response:** 
```
The validation failed due to a column mismatch error between the first and second rows.
```

**Prompt:** 
```
Validate this grid: "header header\nheader footer"
```

**Response:** 
```
The template is valid and forms a consistent 2x2 structure.
```

## Capabilities

### Detect column mismatches
It finds when rows in your grid have different numbers of columns.

### Verify area integrity
It ensures every named area forms a solid, unbroken rectangle.

### Spot layout holes
It identifies gaps or missing pieces within your grid definitions.

### Confirm structural soundness
It checks that the entire template string is consistent and valid.

## Use Cases

### Broken layout detection
A developer asks their agent to create a dashboard, but the columns don't align. The MCP flags the error immediately.

### Component testing
When building new UI components, you use the validator to ensure the grid-template-areas string is perfectly rectangular.

### Code review automation
An agent generating CSS for a pull request uses this MCP to verify that no irregular shapes were introduced into the codebase.

## Benefits

- Stop layout breaks by catching mismatched column counts in your template strings.
