Frequently Asked Questions
Do I need any software or coding app to write HTML?
No. Notepad (on Windows) or TextEdit (on Mac) is enough. VS Code is better but not required for beginners.
How do I share my website?
Right now it works only on your computer. To share it online, you need web hosting (free options: Vercel, Netlify, GitHub Pages). Upgrade to this after your first project.
Is JavaScript hard?
JavaScript is one of the easiest programming languages to learn. This button project teaches the core: variables, events, and functions. That is 80% of what you need.
Can I use this as my school Computer Science project?
Yes. This is a perfect Class 11/12 project. You can expand it (add more features, better CSS, more interactivity) to match your school requirements.
