Flex

Flex is a software tool used in web development that helps create layouts that adapt smoothly to different screen sizes and devices. It allows elements within a page to distribute space dynamically, either by stretching, shrinking, or aligning content as needed. Think of it as a flexible arrangement system that ensures websites look good and function well whether viewed on a phone, tablet, or desktop. Flex makes designing responsive, organized, and user-friendly interfaces more intuitive by providing control over how elements grow, shrink, and align within their containers.
