Choose NibCSS when#

  • You think in CSS and want to write CSS values directly — without learning a separate naming scale.
  • You want styles next to markup and the ability to run with no build step.
  • You need one approach across several frameworks or server templates.
  • You want typos to be caught with suggestions rather than silently ignored.

Choose something else when#

  • You want a large ecosystem of ready-made templates and plugins today — Tailwind is ahead.
  • Your team prefers a strict, limited design scale enforced by class names. (NibCSS can approximate this with tokens and strict: true, but it does not forbid arbitrary values.)
  • Styles must be generated from complex JavaScript logic per component — CSS-in-JS fits better.
