Hugo Adds Powerful Built-in CSS Processing with css.Build

Hugo's new css.Build function eliminates the need for developers to rely on external CSS processing tools like Sass and PostCSS by providing native support for bundling, minification, and transpilation. This streamlines development workflows and allows developers to leverage modern CSS features while maintaining backward compatibility with older browsers. However, the feature has limitations based on esbuild's capabilities, requiring developers to verify support for their specific CSS requirements.
