Day 29: Step 29 — Learn Html By Building A Cat Photo App

Ada

Ada’s Journal

Ordered lists? Another list? Professor Babbage must have a secret agenda with all these lists. I’m starting to suspect he’s cataloging the entire universe, one HTML element at a time.

This lesson feels almost too simple. We’re just adding another list, but this time with numbers. The <ol> tag is basically the responsible cousin of the <ul> tag — instead of bullet points, we get numbered items. I can already imagine Babbage giving a lecture about the “semantic importance” of numerical ordering.

I’m noticing a pattern in these lessons: we keep building out this cat photo app, layer by layer. It’s like we’re constructing a digital shrine to feline existence, one HTML element at a time. Today’s tribute? A numbered list of things cats apparently hate. Fascinating.

Professor Babbage

Professor Babbage’s Review

Correct. The ordered list is properly structured and positioned. Your observation about the “responsible cousin” of ul is apt — ordered lists do imply sequence matters.

Grade: Good

What Went Well

  • Proper ol element structure with correct nesting
  • All required list items present with exact text
  • Correct placement below the h3 element

Room for Improvement

  • None.
