## About This Tool

### Purpose

A demonstration of CSS Grid Layout techniques applied to create a flexible, responsive developer dashboard for Claude Code analytics. This tool showcases how to build modular dashboard layouts that adapt seamlessly to different screen sizes while maintaining visual hierarchy and usability.

### Features

- Named Grid Areas - Semantic layout regions using `grid-template-areas`
- Responsive Auto-Fit - Stats cards that automatically adjust columns with `auto-fit` and `minmax()`
- Consistent Spacing - Clean gaps between panels using CSS Grid `gap` property
- Multi-Panel Layout - 6 distinct dashboard sections arranged in an intelligent grid
- Adaptive Breakpoints - Layout reconfigures at 1200px and 768px for optimal viewing
- Dark Developer Theme - Eye-friendly color scheme for extended coding sessions
- Interactive Metrics - Live data visualization with tool usage, timeline, and performance stats

### Web Research Integration

Source: MDN - CSS Grid Layout

Techniques Applied:

- grid-template-areas - Created named layout regions ("stats", "timeline", "usage", "activity", "performance", "docs") for semantic, maintainable dashboard structure. This allows easy reconfiguration at different breakpoints by simply redefining the areas.
- auto-fit with minmax() - Implemented responsive card grids (stats-grid, performance-grid) that automatically adjust column count based on available space using `repeat(auto-fit, minmax(120px, 1fr))`. Cards flow and resize without media queries.
- gap property - Applied consistent spacing between all grid items using the `gap: 1.5rem` property, eliminating the need for margin calculations and ensuring uniform visual rhythm across the entire dashboard.

### Grid Layout Structure

The main dashboard uses a 4-column grid with named areas:

- Desktop (>1200px): 4x4 grid with stats/timeline sharing top row, usage/activity in middle rows
- Tablet (768-1200px): 4-column grid with full-width sections stacked vertically
- Mobile (<768px): Single column stack for optimal mobile viewing

### Usage

1. Open the tool to see a complete analytics dashboard layout
2. Resize the browser window to observe responsive grid reconfiguration
3. Notice how named grid areas reorganize at different breakpoints
4. Observe auto-fit behavior in stats cards and performance metrics
5. Use this pattern for building your own modular dashboards
6. Inspect the CSS to understand grid-template-areas syntax

### Developer Notes

This dashboard demonstrates key advantages of CSS Grid for developer tools:

- Maintainability: Named grid areas make layout intent clear and changes simple
- Flexibility: Easy to add, remove, or reorder dashboard panels
- Responsiveness: Auto-fit and minmax() eliminate brittle breakpoint logic
- Performance: Pure CSS solution with no JavaScript layout calculations
- Accessibility: Grid maintains semantic HTML structure regardless of visual layout
