Clean Css
clean-css is a Node.js CSS optimizer that functions as a minifier, bundler, and source map generator. It reduces stylesheet file sizes by removing whitespace and comments while optimizing colors and units to improve page load times.
The tool features a plugin-driven pipeline that allows for custom optimization transformations and the preservation of specific code fragments via marker-based exclusions. It includes browser compatibility targeting to ensure optimized styles remain functional across specified browser versions.
The project provides capabilities for bundling multiple stylesheets into a single output, asynchronously inlining remote resources, and rebasing relative asset URLs. It also generates source maps to link optimized stylesheets back to their original source code.
Features
- CSS Minification - Reduces stylesheet file sizes by removing unnecessary whitespace, characters, and redundant rules.
- Stylesheet Bundling - Combines multiple stylesheets into a single optimized bundle to reduce network requests.
- Source Map Generators - Generates mapping files that link minified CSS back to the original source code for debugging.
- CSS Bundlers - Aggregates and processes multiple CSS files into a single output to improve page load performance.
- CSS Minifiers - Shrinks stylesheet file size through rule merging, character removal, and color optimization.
- CSS Optimizers - Provides a comprehensive suite of tools for shrinking and optimizing CSS files to improve page load times.
- CSS AST Transformations - Implements programmatic modification of CSS structures through tree traversal and rule merging.
- CSS Transformation Plugins - Allows the integration of custom plugins to perform specialized CSS transformations during the optimization process.
- Browser Compatibility Configurations - Automates code compatibility adjustments by targeting specific browser versions.
- Plugin-Based Architectures - Features a plugin-driven architecture that allows external modules to hook into the CSS transformation pipeline.
- Browser Compatibility & Utilities - Adjusts optimization levels to ensure resulting styles remain functional across specified browser versions.
