did you check your console to see the result of this console.log? You appear to be using a property reserved for arrays on an object. My log shows me "My house number is undefined" which is not the expected behaviour.

I ran your demo and I can see the buttons move up and down the page when the image changes to the next slide. if you had to improve the UX of this app, what would you change?

Thanks for the feedback! I would improve the UX by keeping the navigation buttons fixed in a consistent position, so they don’t shift when the image changes. I’d also add smoother transition effects between slides and ensure the carousel is responsive for different screen sizes.

this is an interesting approach but I am sure there is a better way to do this. Have you tried separating the image and control buttons on the page. Perhaps having different containers for them?

<img id="carousel-img" src="./assets/cute-cat-a.png" alt="cat-pic" />

<button type="button" id="backward-btn">Backwards</button>
<button type="button" id="forward-btn">Forward</button>

<button id="auto-forward">Auto Forward</button>
<button id="auto-backward">Auto Back</button>
<button id="stop">Stop</button>

<label for="delay-input">Delay between images (seconds): </label>
<input type="number" id="delay-input" min="1" max="10" value="2" />

Thank you! I appreciate the feedback.
I’ll keep refining the UX to make the carousel smoother and more consistent.
