It's a very broad question but of course you can. Even with pure css, no packages or other languages, you can create stuff like hover animations (moving elements on your webpage based on where your mouse goes and what you click) and because of modern HTML/css you can also make it responsive for other devices.

The first steps in creating one is doing a bit more research on the setup of a text editor (where you will code in) and then trying to either learn the code from a tutorial or let a language AI like ChatGPT write you one.

This is a great place to start for a beginner: W3Schools - HTML Editors

P.S. W3Schools is a very complete online documentation hub for web development and is great for beginners, so check out their tutorials and content.
