Sfumato is a command line interface (CLI) tool that generates CSS for your web-based projects. You can create HTML markup and use pre-defined utility class names to style the rendered markup, without actually writing any CSS code or leaving your HTML editor!
The resulting HTML markup is clean, readable, and consistent. And the generated CSS file is tiny, even if it hasn't been minified!
Check out the documentation and try Sfumato on your next web project.
