Bootstrap
Bootstrap is an open-source frontend framework for responsive websites and web applications. It provides a grid system, utility classes, design foundations, and components such as navigation, dialogs, and forms. Interactive components use JavaScript; current Bootstrap versions no longer require jQuery.
Bootstrap can accelerate prototyping and consistent interfaces, but it does not replace a custom UX and design concept. Unmodified standard components can appear generic, while unnecessary bundled features increase payload. Production projects should assess design variables, components, delivered code, accessibility, and upgradeability deliberately.
Frequently asked questions
Bootstrap is an open-source frontend framework with CSS and JavaScript building blocks for responsive interfaces.
No. It helps when its components and conventions fit the project. Custom CSS may be leaner for small or highly distinctive websites.
