Final answer:
Bootstrap is a front-end web development framework, not a back-end framework.
Step-by-step explanation:
Bootstrap is a framework for front-end web development, not back-end web development. It is a popular open-source toolkit for designing responsive and mobile-friendly websites. Bootstrap provides a collection of CSS and JavaScript components that make it easier to create a visually appealing and interactive user interface.
For example, Bootstrap includes pre-built CSS classes for creating responsive grids, typography, forms, buttons, navigation menus, and more. These components can be customized and easily integrated into a web project, saving developers time and effort.
In summary, Bootstrap is a front-end web development framework, not a back-end framework.
