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.
