What is Bootstrap?

Bootstrap is a free, open-source front-end framework designed to simplify the creation of responsive and mobile-first websites. Built using HTML, CSS, and JavaScript, it offers pre-designed components, templates, and utilities to help developers build consistent, visually appealing, and responsive web pages quickly.

Key Features of Bootstrap

What is Bootstrap?
  • Responsive Design

Provides a grid system with responsive breakpoints for layouts.
Dynamically adjusts web pages for different screen sizes.

  • Reusable Components

Includes pre-styled UI elements like buttons, forms, modals, tooltips, and more.
Built-in JavaScript components work without external libraries like jQuery.

  • Mobile-First Approach

Bootstrap Breakpoints


Bootstrap’s grid system is based on breakpoints that allow developers to create responsive layouts. These breakpoints adapt content to fit different screen sizes:

Extra Small (xs): < 576px
Small (sm): ≥ 576px
Medium (md): ≥ 768px
Large (lg): ≥ 992px
Extra Large (xl): ≥ 1200px
Extra Extra Large (xxl): ≥ 1400px

Breakpoints are used to define when content should adjust or change layout. Developers can combine these with utility classes like .col-sm-6 or .d-md-none to control the visibility and alignment of elements based on screen size.
