Core Framework is a free platform for building and customizing modular CSS frameworks through a visual interface. It is designed for web developers and designers who need a tailored, organized approach to styling without starting from scratch or managing complex codebases.

Visual Interface: Configure every aspect of your CSS framework using a graphical interface, allowing you to adjust settings and see changes in real-time without manual coding.

Modular Utility System: Build with a utility-first approach, enabling you to add, remove, or edit individual CSS classes, variables, and components to fit specific project needs.

Custom Color Management: Define and manage color palettes visually, with tools to generate shades, tints, and transparent variants automatically, output as CSS variables and utility classes.

Responsive Scaling Tools: Create fluid typography and spacing scales using calculators that let you set minimum and maximum values, generating appropriate CSS for consistent responsiveness.

Export Ready Stylesheets: Once configured, download or export a complete, auto-prefixed, and organized CSS file that is production-ready for integration into any website or application.
