Build me a simple personal learning hub for my notes, with sections for CSS, JavaScript, React, Next.js, and Node.js.

I want it to feel clean and easy to browse, like a place where I can keep short lessons, examples, and quick reminders in one spot. Make it simple to open a topic, read the notes, and jump between sections without any clutter. If it helps, add a homepage that shows the main categories and lets me add or edit notes later, even if the editing part is basic for now.

Keep the design minimal and readable, and make sure it works well on desktop and mobile. Use the existing learning topics as the guide, and if you need anything current from the docs or best practices, look it up online first.
