Description: The Bootstrap grid is a design system that allows for responsive design in web applications. This system is based on a structure of rows and columns that facilitates the organization of content in the user interface. Bootstrap employs a fluid design approach, meaning that elements automatically adapt to the screen size of the device, whether it is a desktop computer, tablet, or mobile phone. The grid is divided into 12 columns, allowing developers to create complex and flexible layouts by combining different column widths. Additionally, Bootstrap includes predefined classes that simplify the implementation of the grid, enabling designers and developers to focus on the functionality and aesthetics of the website. This system not only enhances the user experience by ensuring that content is accessible and readable on any device but also accelerates the development process by providing a solid and consistent foundation for creating responsive web applications. In summary, the Bootstrap grid is an essential tool for any developer looking to create modern and responsive websites.
