Bootstrap framework

Bootstrap is a popular front-end web development framework that provides a set of pre-built HTML, CSS, and JavaScript components and tools for building responsive, mobile-first websites and web applications.

Bootstrap was developed by Twitter and was initially released in 2011. Since then, it has become one of the most widely used CSS frameworks, with a large and active community of developers and contributors.

Here are some of the key features and benefits of using Bootstrap:

• Responsive design: Bootstrap provides a set of pre-built CSS classes and components that make it easy to create responsive layouts that adjust to different screen sizes.
• Mobile-first approach: Bootstrap’s design philosophy is based on a mobile-first approach, which means that the framework is optimized for mobile devices and then scaled up to larger screens.
• Pre-built components: Bootstrap provides a large collection of pre-built HTML, CSS, and JavaScript components, such as navigation bars, forms, modals, and carousels, that can be easily customized and integrated into your web projects.
• Consistent styling: Bootstrap provides a consistent and cohesive set of styles and components that can help to improve the overall look and feel of your web projects.
• Extensibility: Bootstrap can be easily extended and customized using custom CSS and JavaScript, as well as third-party plugins and add-ons.
