DESIGN NOTE:

Don't worry, this is a hidden canvas. You can delete it after you read this. FYI, this top section is going to look strange, but it functions beautifully in the live preview, so don't delete the second section that appears blank / to have a weird gap! It's so the text will load over it beautifully. 

Since the text is white and hard to see, just briefly turn the text black to edit, then back to white, or you can make it black and change the top background colors instead! — Jen
