Bulma is a free Flexbox-based, open-source CSS framework. Bulma solves a lot of difficulties whether you need a visual element, or you want to understand how to codify a component. The main benefit of using Bulma is that it is fully Flexbox-based in its box model. No more floats and percentages with CSS. The CSS framework has made it easy to create components and patterns for UI design. To create a cohesive interface for front-end developers, Bulma utilizes several techniques. We just need to describe the design of our website using semantic classes that are not elements or, in other words, idiomatic templates. It is possible to think of these semantic templates as interconnecting building blocks we use to quickly build websites. These components are also out-of-the-box responsive, meaning we can concentrate more on our content than on the code. Features of Bulma: Responsively Well-documented Solid foundation Various components Modular Bulma Advantage: Lightweight Easy to Use Responsive Design Based on Flexbox Highly customizable and modularizable Simple syntax Bulma Disadvantage: The CSS of this framework runs very slow on the IE web browser. It is still in the development phase and the final version is yet to come. Fairly new, not as large of a community Conclusion: Bulma is unbelievably lightweight and simple to use, similar in design to the Bootstrap CSS. It makes it simple for developers with any background to customize and create applications, and it also ensures that front-end experts can build next-level designs with integrated Flexbox responsivity.
