This first image is of how the home page would look like

After scrolling down on any of the pages, the icons would shrink up into words and scrolling up would expand them back into icons

The shopping cart icon would expand slightly when hovered on and the items in the shopping cart would pop up.

Lastly, the piano and books page would have a similar look in that they would be separated into sections based on some criteria. For pianos, they would be separated by piano brands while for books they, they would be separated by what instruments the books would be for. A search bar would also pop up at the top right of the main body for people to directly search for the item they are looking for. Each section would allow users to scroll through them as well.
