Foundation Building Blocks

In plain words

Foundation Building Blocks is a free library of pre-coded UI components designed to accelerate web development. It provides developers with ready-made interface elements that can be integrated into projects, reducing the time needed to build common design patterns from scratch. The library serves developers and development teams who want to speed up their workflow by using tested, reusable components rather than coding everything from the ground up.
