i spent the week basically coding a huge chunk of the backend/frontend of the extension and also learning a lot about how Chrome Extensions work using the docs online and learned how to handle different events like the service workers that work in background.js and the content scripts that will run and inject html into websites like the one shown in the image below.
actual popup that shows for the browser extension is can be seen here which uses basically html with javascript that populates it with the “distractor” tabs
the dino is also animated on the actual extension using the translate3d css tag
