Interactive CSS Grid Layout Template Generator and Code Tool

CSS Grid Layout Template Builder Specification

Overview

This web application is a visual interface that simplifies the creation of complex CSS Grid layouts. It allows developers to define columns, rows, and named grid areas without writing manual code, providing an instant preview and exportable CSS.

Layout Structure

• Header: Contains the app name and a global reset button.
• Sidebar (Left): Controls for grid dimensions (Number of columns/rows, gap settings in px/rem/fr).
• Workspace (Center): A canvas where users can draw grid cells, name areas, and resize columns/rows interactively.
• Inspector (Right): Real-time code display panel with syntax highlighting and a 'Copy to Clipboard' button.

Key Features

1. Dynamic Grid Editor: Add or remove columns and rows via buttons or keyboard shortcuts.
2. Area Naming System: Assign semantic names (e.g., 'header', 'sidebar', 'main', 'footer') to specific grid regions.
3. Gap Adjustment: Real-time sliders for row-gap and column-gap.
4. Responsive Preview: Toggle buttons to test the layout at desktop, tablet, and mobile breakpoints.
5. Unit Flexibility: Toggle between px, %, and fr units for precise sizing.
6. Code Export: Automatically generates formatted CSS blocks for grid containers and grid items.
7. Presets Library: Common patterns like 'Dashboard layout' or 'Card grid' available as starting points.

Visual Design & Animations

• Color Palette: High-contrast neutral palette (whites, grays, and deep blues) to ensure the focus remains on the layout.
• Animations:
  • Dragging to resize columns should have a fluid 'rubber-band' feel using CSS transitions.
  • Smooth fading animations when adding or removing grid tracks.
  • Visual feedback (highlighting) when hovering over defined grid areas.

Interactive Specifications

• Drag-and-Drop: Use HTML5 drag-and-drop or pointer events to adjust column/row sizes.
• Direct Editing: Click on an area name to rename it, which instantly updates the grid-template-areas CSS property.
• Copy Functionality: Single-click copy for the CSS block, with a toast notification confirmation.
