Look inside

My Little Cookie Shop’s website looks pretty nice, but there’s a problem with an accordion feature on the store’s page. Instead of allowing the user to expand or collapse pastry categories, the content abruptly appears and vanishes. To make sure Max’s competitive edge doesn’t vanish, too, you’ll make the sections glide open and close, as well as fix an arrow’s rotation problems, using CSS and JavaScript. Also, to respect all users, you’ll use media query to disable animations for users whose browser settings indicate they prefer reduced motion.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
