Product Preview with Cart Animations and Background Styling

What are you most proud of, and what would you do differently next time?

I am happy with the slight design changes that I made. The background has a little bit more texture now without being overwhelming, and the Add to cart button has a little bit of animation to spice it up. I think I might simplify animations in the future. I have a feeling that my approach is too cumbersome - but I need to research this a little more.

What challenges did you encounter, and how did you overcome them?

I had a little bit of difficulty determining how to use the <picture> element at first. Once I figured it out I fell in love with how simple it is to responsively swap out images.

What specific areas of your project would you like help with?

Any feedback is great. If anybody has insight into css animations or the logic that controls them in the JS, I'd love some resources.
