Hi,Yes, you would need to modify the application.To limit the zoom extent, you need to follow the developer instructions and edit app/storymaps/core/Core.js to include the maxZoom property to the arcgisUtils.createMap call.To style the carousel, apply those instructions with a CSS like:#footerDesktop .carousel li:nth-child(2) {
border-right: 2px solid #CCC;
}
