Hello.
This html is in an outside file for dynamic fetching. The file, and sub parts are deliberately not valid XML because we have no guarantee that we will be given valid XML in a production environment. There are multiple bits of text in the file, of various appearances. In a production setting these bits would come from different sources, but for the test page we do it this way.

Here we have the self rolling image again. This time it is setting up without using an id, so that it does not need to worry about id confusion.
