@mfickler The notebox is working, if you look at your first box you have it showing up properly – http://i.imgur.com/H8DWRCX.png
Your second box is setup with the black box code, but you have the words “This is a Note box.” added inside which is probably what is making it look confusing – http://i.imgur.com/uFfYOt3.png
If you look at your code, the first box shows this –
<div class="note-box">
While the second box (in black) shows this –
<div class="black-box">
The second box is supposed to be black since you added the “black-box” code but you added "This is a Note box."
as the text. Let me know if you have any questions.
