PostCSS

PostCSS is a tool used by web developers to enhance and streamline CSS, which is the language used to style websites. It works by processing CSS code through plugins—small, specialized programs—that can automatically add features, fix issues, or optimize styles. This allows developers to write cleaner, more efficient CSS and easily incorporate modern CSS features or workflows. Essentially, PostCSS acts like a customizable pre-processor that improves how styles are written, maintained, and applied, making the overall styling process more efficient and adaptable for complex web projects.
