    Responsive Design

    Bootstrap includes a wide range of pre-built components such as navigation bars, buttons, forms, modals, and more. These components are customizable and can be easily integrated into your projects.

    JavaScript Plugins

    Bootstrap comes with a set of JavaScript plugins that add interactivity to your web pages. These plugins include features like modals, tooltips, carousels, and dropdowns. They can be used with data attributes or JavaScript code.
