Bulma is a modern CSS framework based on Flexbox.

Bulma is in early but active development! Try it out now:

npm install bulma

Feel free to raise an issue or submit a pull request.

Bulma is a CSS framework. As such, the sole output is a single CSS file: bulma.css

You can either use that file, "out of the box", or download the Sass source files to customize the variables.

There is no JavaScript included. People generally want to use their own JS implementation (and usually already have one). Bulma can be considered "environment agnostic": it's just the style layer on top of the logic.

This repository is only for the Bulma source files.
The website (which includes the documentation) is in another repo: https://github.com/jgthms/bulma-website

If you encounter a typo or a lack of documentation, submit an issue there.

Bulma uses autoprefixer to make (most) Flexbox features compatible with earlier browser versions. According to Can I use, Bulma is compatible with:

• Chrome 45+
• Edge 13+
• Firefox 43+
• Internet Explorer 10+
• Safari 9+
