Bulma is a CSS framework. This means it provides CSS classes to help you style your HTML code. As such, the sole output is a single CSS file: bulma.css. It provides ready-to-use frontend components that you can easily combine to build responsive web interfaces. Because Bulma solely comprises CSS classes, the HTML code you write has no impact on the styling of your page.
The framework is based on Flexbox.
This is free and open source software.
Key Features
- 100% responsive – every element in Bulma is is mobile-first and optimizes for vertical reading.
- Modular – only import what you need. Bulma consists of 39 .sass files that you can import individually.
- Easy to learn and customize courtesy of hundreds of Sass variables. These variables exist at 4 levels:
- initial variables: global variables with literal values
- derived variables: global variables with values that reference other variables, or are computed
- generic variables: for the HTML elements which carry no CSS class
- element/component variables: variables that are specific to a Bulma element/component
- Modern – built with Flexbox, a CSS 3 web layout model. It is in the W3C’s candidate recommendation stage. The flex layout allows responsive elements within a container to be automatically arranged depending upon screen size.
- No JavaScript is required. No CSS knowledge is needed either.
