This document discusses using the Foundation front-end framework for both prototyping and production. It notes that Foundation is useful for prototyping because it allows for low-fidelity, quick iteration optimized for development speed. However, it also argues that Foundation is suitable for production use, as it results in high-fidelity, stable, highly customized sites and apps optimized for end user speed. The document promotes Foundation by highlighting its large community, wide usage in both small and large projects, and emphasis on best practices like responsive design, accessibility, and modern coding standards.
