CSS Flexbox is a layout module in CSS that provides a flexible and efficient way to lay out, align, and distribute space among elements within a container. Flexbox allows items to align vertically or horizontally and can be used to build responsive and flexible web designs with ease. It provides greater layout control on web pages, allowing for dynamic and intricate designs that adjust to viewport size, making it a powerful tool for responsive web design.
