VERDICT

Should I use Bulma?

Free, open source CSS framework based on Flexbox, built with Sass. - bulma.io

Worth it. Use Bulma if you want a free, lightweight, CSS-only framework and are happy to write your own JavaScript. Skip it if you need built-in interactivity, official React bindings, or vendor support.

Confidence

Reddit, r/web_design
“I'm always suspect of a css framework which has a website that doesn't work properly on mobile.”
