Halfmoon is a highly customizable, drop-in CSS replacement for Bootstrap 5, built with CSS variables and three core themes with dark mode support. It ships no JavaScript of its own, relying entirely on bootstrap.bundle.js so it works with any Bootstrap-compatible component library.

Use cases

  • replace bootstrap css with a more customizable alternative
  • add dark mode to a bootstrap-based website
  • build a responsive dashboard with a css framework
  • create custom themes using css variables
  • support rtl layouts in a bootstrap project
  • use bootstrap components with react or vue without changing js

When to choose

  • you already use Bootstrap 5 and want a drop-in stylesheet swap with dark mode
  • you need deep theming via CSS variables with minimal effort
  • you want to keep using bootstrap.bundle.js and existing Bootstrap component libraries

When to avoid

  • you need a framework with its own JavaScript components
  • you want utility-first styling like Tailwind
  • you don't use Bootstrap and prefer a standalone design system
