Automatic.css (ACSS) is a CSS utility framework designed for developers and designers who build sites with visual page builders. It provides a structured system of classes and variables to apply styles, aiming to reduce repetitive coding and enforce design consistency across a project.

• Utility Class System: Apply common styles like spacing, colors, and typography directly in the page builder using predefined classes, reducing the need to write custom CSS for every element.
• Automatic Responsive Design: Built-in classes handle adjustments for different screen sizes, removing much of the manual work required to make layouts look correct on mobile devices.
• Global Design Tokens: Manage colors, spacing scales, and typography from a central location. Changing a token value updates it everywhere it's used, making site-wide styling changes quick.
• Component Styling with Variables: Style reusable components using CSS custom properties (variables) for consistent and maintainable code, which works with methodologies like BEM.
• Development Utilities: Includes features to solve common front-end issues, such as automatic unit conversion, focus styling for accessibility, and tools for managing clickable areas and text balance.
