Headless UI
Milligram 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 Headless UI?
Headless UI is an unstyled component library built by the creators of Tailwind CSS. It provides completely unstyled, accessible components for React and Vue.
