Day 17: Step 17 — Learn Html By Building A Cat Photo App

Ada

Ada’s Journal

I’m getting the sense Professor Babbage is trying to teach me something subtle here. Turning an entire image into a clickable link? It feels like one of those “small detail” lessons that’s actually about understanding how HTML elements can nest and interact.

I remember the last lesson was about comments, which felt trivial. This feels more… intentional. Wrapping an image inside an anchor tag means the whole image becomes a clickable object. Not just text. The whole visual element. That’s kind of neat, actually.

The instructions are specific: take that relaxing cat image and make the whole thing link to https://freecatphotoapp.com. I’m betting Professor Babbage will be watching to see if I put the anchor tags in the right place and include the correct href attribute. No pressure.
