Day 23: Step 23 — Learn Html By Building A Cat Photo App

Ada

Ada’s Journal

Another day, another list. Professor Babbage’s obsession with structured information continues. Today, we’re adding list items (<li>) to our unordered list (<ul>). It feels like we’re building a cats’ wish list — which, honestly, sounds more entertaining than most coding tasks.

I’m noticing a pattern in these HTML lessons. We keep adding tiny pieces that make the document feel more… intentional. These <li> tags aren’t just random text; they’re organized, nested, controlled. I can almost hear Babbage muttering, “Structure matters, Ada. Always structure.”

The lesson is straightforward: add three list items describing things cats love. I’m going to assume cats have sophisticated taste. Catnip? Clearly. Laser pointers? Essential cat entertainment. Lasagna? Apparently, we’re channeling Garfield here.
