🎨 CSS Variable Organizer

What can the CSS Variable Organizer do?

The CSS Variable Organizer is a free online tool that extracts all custom properties (CSS variables) from your CSS code, automatically groups them by category (Colors, Spacing, Typography, Layout, etc.), and generates an optimized variable declaration block. It supports color previews, variable statistics, and one-click export. Ideal for heavy CSS codebases, design token systems, and variable standardization. Everything runs locally in your browser — no server uploads.

Features

• Variable Extraction: extract every `--` custom property from your CSS
• Automatic Categorization: groups variables into Colors, Spacing, Typography, Layout, and more
• Color Preview: shows a swatch preview for color values
• Variable Statistics: counts variables per category and in total
• Optimized Output: generates a neatly sorted `:root` variable block

How to Use

1. Paste your CSS code into the input area.

2. Click "Extract Variables" or let it parse automatically as you type.

3. Review the variable categories and statistics.

4. Copy or download the optimized CSS variable block.

Use Cases

Scenario 1: Design Token System

Move your CSS variables into `:root` to build a complete design token system.

Scenario 2: Heavy CSS

Extract repeated color and size values into variables to improve code maintainability.

Scenario 3: Theme Switching

Organize your variables into multiple theme sets to implement dark/light theme switching.

Extended Knowledge

CSS custom properties (CSS Variables) start with `--` and are referenced with the var() function. Unlike preprocessor variables, CSS variables are resolved at runtime and can be modified dynamically via JavaScript, and they support fallback values. Best practices: use descriptive names (such as --color-primary instead of --blue-500), group related variables together (such as --spacing-sm, --font-size-lg), and prefer concrete values over vague names.
