Bootstrap provides a collection of pre-designed HTML, CSS, and JavaScript components, such as navigation bars, buttons, forms, and more, to help developers build consistent and visually appealing websites.One of the key features of Bootstrap is its responsive design, which means that websites built with Bootstrap automatically adapt and scale to different screen sizes, making them suitable for both desktop and mobile devices.

Responsive Web Design (RWD) is an approach to web design that aims to create web pages that provide an optimal viewing and interaction experience across a wide range of devices, from desktop computers to mobile phones. The goal is to ensure that the website's layout, images, and other elements adapt and respond appropriately to different screen sizes and resolutions. Responsive Web Design aims to create a seamless user experience, eliminating the need for separate designs or versions for different devices. This approach has become increasingly important with the proliferation of various devices and screen sizes in the modern digital landscape.
