Vanilla Framework CSS
You know how building a website can feel like a lot, especially when you’re trying to style every little thing yourself? Buttons, forms, layouts… it adds up fast. That’s where UI frameworks really save the day. They give you a bunch of premade design elements that you can just drop in and go. It’s like having a design starter pack that helps your site look clean and professional, without spending forever tweaking the details.
What is Foundation?
Foundation by Zurb is a responsive front-end framework designed for creating responsive and accessible websites quickly. It is known for its mobile-first approach and powerful grid system, Foundation provides a set of prebuilt components and tools that help developers create professional websites, prototypes, and production-ready apps.

What is Vanilla Framework CSS?
Vanilla Framework is an open-source, lightweight, and extensible CSS framework developed by Canonical (the creators of Ubuntu).

Unlike component-heavy frameworks such as Bootstrap or Foundation, Vanilla focuses on clean base styles, responsive layouts, and utility classes that can be extended into full design systems.
