Fomantic-UI
Spectre 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 Fomantic-UI?
Fomantic-UI is a modern version of the popular Semantic UI, made and improved by the community. It is a tool for building websites that are responsive, easy to style, and user-friendly, fast.
It focuses on semantic class names that read like natural language, making code more intuitive and easier to understand. Since it’s a fork, it has continued where Semantic UI left off, with new features, updates, and active maintenance by the community.
Key Features of Fomantic-UI
