Why choose Bulma
Simple grid system
To build a Bulma grid, you only need a single .columns container to wrap as many .column items as you want.
Easy-to-learn syntax
With simple readable class names like .button or .title, and a straightforward modifiers system like .is-primary or .is-large, it’s easy to pick up Bulma in minutes.
More about modifiers
Font Awesome 5 support
Bulma is compatible with both Font Awesome 4 and Font Awesome 5 thanks to the .icon element.
100+ useful CSS helpers
Bulma ships with more than 100 helpers to specify color, display, and spacing.
Responsive helpers – Typography helpers – Other helpers
No JavaScript
By focusing only on CSS, Bulma provides a lightweight solution that can easily be implemented in any development context.

Why choose Bootstrap
jQuery plugins
Bootstrap includes useful jQuery plugins to add interaction to your website.
Big community
Considering how long it has been around, Bootstrap has a larger community than Bulma. As a result, more tools (like theming and plugins) are available, and more questions are answered around the internet.
Internet Explorer compatibility
While 90% of Bulma works in IE11, Bootstrap has better compatibility with this browser.
Additional elements
Bootstrap has some elements like list group, wells, or page header that Bulma doesn’t have.
Accessibility
Bulma has introduced some support for accessibility, but Bootstrap has strong and pervasive compatibility with WCAG 2.0 guidelines.
