Fix: Expandos no longer show pointer cursor on whole element

[danielledeleo]

Proposed changes

Expandos were showing the pointer cursor on all elements in the expanded section, not just the expando link.

Also of note is the change to the first example that forces a <p> tag to be generated, improving whitespace.
