Bootstrap is the most popular HTML, CSS, and JavaScript framework for building responsive, mobile-first websites and web applications. It provides a comprehensive set of prebuilt components, a grid system, and Sass-based styling for faster front-end development.
Use cases
- build a responsive website without writing custom css
- rapidly prototype a web app ui
- create a mobile-first landing page
- style forms, modals, and navbars with prebuilt components
- use a grid system for page layouts
- customize theme colors with sass variables
When to choose
- you need a battle-tested, widely documented css framework with a huge ecosystem
- you want to ship a responsive ui quickly without a design system of your own
- your team wants consistent, prebuilt components like dropdowns, modals, and carousels
When to avoid
- you need a highly custom, unique visual design out of the box
- you prefer utility-first styling like tailwind css
- you want a full application framework with state management rather than styling
