WEB TECHNOLOGY LAB — SIMPLE WORKING CODES (EXPERIMENTS 2–12)

Each experiment has its own folder. HTML experiments use index.html and styles.css.
Experiment 7 files are standalone JavaScript programs.

HOW TO RUN
1. HTML/CSS/DOM experiments: open that experiment's index.html in a browser.
2. Experiment 7: install Node.js, open a terminal in the experiment folder, run:
   node 7a.js   (change the filename for the required experiment)
3. Experiment 9 (AngularJS): open index.html while connected to the internet (AngularJS CDN).
4. Experiments 10–11 (React): these use React through CDN and Babel; open index.html with internet access.
5. Experiment 12 (Node.js + MongoDB): install Node.js, install MongoDB locally or use MongoDB Atlas.
   In the folder run: npm install, then npm start. Set MONGO_URI in your environment if needed.
   This is a basic CRUD API; use the browser or an API client to test the endpoints.

All designs are intentionally plain black and white. Experiment 3 uses a simple inline SVG map-style image so it works without a separate image download; hotspot coordinates are illustrative.
