Introduction

In this tutorial, we'll explore a JavaScript function that generates CSS variables based on the input CSS rules. The goal is to create a more maintainable and flexible stylesheet by utilizing CSS variables.

Code Overview

Here's a JavaScript function that takes an input CSS string, extracts the rules and properties, and generates CSS variables:

function generateVariables() {

    // ... (your code)

}

How It Works

The function uses regular expressions to parse the input CSS and extract selectors, properties, and values. It then generates unique CSS variables for each distinct property value and updates the stylesheet accordingly.

Usage

Copy and paste your CSS code into the input field.

Click the "Generate" button to create CSS variables.

View the generated CSS with variables and copy it.
