If I am not mistaken, you need to rearrange some of the content and fix some of the tagging.
Elements: html, h1, body – this is just for clarification
Tags are sorted like this -
Opening tags <[insert element]>
Closing Tags </[insert element]>
Together <[insert element]>…your content goes here…</[insert element]>
You are missing an opening tag for the body element
CatPhotoApp
goes directly under the opening tag of the opening tag of the HTML element
and the next step is asking you to make an h2 element for Cat Photos which would be this
Cat Photos
Remember to read carefully, use the correct tags, organize, and don’t be afraid to google or watch youtube.
