Our verdict
Bulma is a ready-made styling kit: you include one CSS file and use its prebuilt classes for layout and common UI pieces, with no JavaScript included. Tailwind CSS is a set of small utility classes you combine directly in your HTML to build a custom look from scratch. Bulma suits people who want a quick, consistent baseline with less custom CSS; Tailwind suits developers who want full control of their own design and are comfortable with utility-class markup.
Pick Bulma if you want a quick, consistent styling baseline with a single CSS file and you're happy to add your own JavaScript for interactive parts.
Pick Tailwind CSS if you're building your own custom interface and prefer styling elements directly in your markup with small utility classes.

What each one is
Bulma
Bulma is a CSS framework based on Flexbox. It ships as a single CSS file with ready-made classes for layout and common interface elements, so you can style a web page without writing much custom CSS. It contains no JavaScript, so you add your own scripts for any interactive behavior.
Tailwind CSS
Tailwind CSS is a CSS framework built around small, single-purpose utility classes that you combine directly in your HTML or templates to style elements. Instead of writing separate stylesheets for each component, you apply classes for layout, spacing, color, and typography. The README describes it as a way to rapidly build custom user interfaces.

- Projects that already have their own JavaScript and only need a style layer

Strengths
Bulma

- Customizable through Sass source files and variables
Tailwind CSS
- Utility classes let you style elements without leaving your markup
- The project is widely used, with about 98,000 GitHub stars and an MIT license
- Documentation is hosted at tailwindcss.com and discussions are active on GitHub
Not ideal for
Bulma
- People who need interactive components like modals or dropdowns out of the box, since Bulma has no JavaScript and you must supply it
- Projects that must support Internet Explorer fully, since the README says IE 10+ is only partially supported
- Teams that want a heavily opinionated design system with a fixed look, since much of the appearance is meant to be customized
Tailwind CSS
- People who prefer writing traditional semantic CSS files; the utility-class approach is a different style of working
- Beginners with no HTML or CSS basics, since the framework assumes you already understand those languages
- Projects that need a ready-made set of visual components out of the box; the README describes a framework for building custom interfaces, not a component library
Trade-offs
Bulma
- Browser support is limited to recent versions of major browsers, with only partial support for IE 10+
- Interactive behavior must be written or added separately
- The README notes the project is in constant development, so details may change between releases
Tailwind CSS
- Heavy use of utility classes can make markup look dense to people unfamiliar with the approach
- The README is minimal and points to the external website for detailed documentation
- Specific setup steps and configuration are not described in the README provided
