postcss-color-hex-alpha enhances CSS color handling by enabling the use of 8-character hex codes (e.g., #RRGGBBAA) for specifying colors with alpha transparency in PostCSS. This plugin interprets these hex codes, translating them into standard rgba() notations, ensuring wider browser compatibility. Streamline your CSS workflow by leveraging concise hex codes for opacity settings directly within your stylesheets. Supports consistent color definition across design systems and simplifies CSS maintainability.
