As of the requirement you don't need any pre-installations to run and test the assignment. Steps:-
- Simply unzip the folder. Make sure all the files are in one folder.
- You can double click on index.html to open the assignment in a server or if you want the visualization of the code then open in VS Code.
- Make sure you have installed the Extension (Live Server).
- Right Click on your mouse and click on Open with Live server.
- Done! The assignment is visual and functional.
N.B: I could've added the routing/hosting via PhP or React but as It wasn't mentioned in the question, I skipped it for ensuring testing friendliness.
If you want to test if the PiP window is dragable or not. Make sure you are dragging by clicking the GREY border of the window preview.
