Tell us what’s happening:
Describe your issue in detail here.
I’ve looked through all of the questions about this. It says: After the h3 element with the Things cats love: text, add an unordered list (ul ) element. Note that nothing will be displayed at this point.
So I added and then I get the error Your ul element should have an opening tag. Opening tags have this syntax: <elementName>
I tried adding , but it’s still wrong. I can’t figure it out. Halp!

  **Your code so far**

Challenge: Learn HTML by Building a Cat Photo App - Step 20

Link to the challenge:

common problem. You wrote u1 instead of ul
( Unordered List ) so the second character is a lowercase L

Omg…I can’t believe I spent this much time on such a silly thing lol! Thank you!
