What are the benefits of using responsive design frameworks like Bootstrap for PHP projects targeting mobile users?

Responsive design frameworks like Bootstrap offer a grid system and pre-built components that make it easier to create mobile-friendly PHP projects. By using Bootstrap, developers can ensure that their websites are optimized for various screen sizes and devices, providing a better user experience for mobile users. This can lead to increased engagement, lower bounce rates, and ultimately higher conversion rates.
