CSX CSS Utilities for TypeStyle

CSX (CSS eXpressions) is a utility library designed to simplify the creation of strongly typed CSS values and functions within TypeScript environments, primarily serving as a companion to the TypeStyle library. It offers a comprehensive set of helpers for common CSS properties and units, such as `color`, `rgb`, `hsl`, `px`, `em`, `percent`, as well as shorthand properties like `margin` and `padding`. The current stable version, 10.0.2, reflects ongoing development with a recent focus on aligning its output more closely with the CSS Object Model (CSSOM) for improved consistency and testability across different browsers and testing setups. This includes changes to color function spacing and the addition of optional alpha parameters for `rgb()` and `hsl()`. CSX maintains an active release cadence, delivering continuous enhancements and bug fixes. Its core differentiator lies in providing a robust, type-safe API for dynamic CSS value generation, significantly reducing runtime errors and improving code maintainability compared to raw string concatenation or less-typed approaches.
