Our goal is to save birds

And this is the text that could accompany it. It is all optional so if you delete it in the Parabola Settings there will be no more caption with the black background. Just like in the next slide.

one bird at a time

You can also use links as well as most other HTML tags and even [shortcodes] inside the columns.
Our Western Location

more food for blue jays
And underneath the columns you can have 2 more text boxes that also support HTML tags and [shortcodes]. You can also choose to have just one text area or none. Deleting all text inside the appropriate input in the Parabola Settings will remove this whole text area.
As you can see it's really all up to you. You are free to do whatever you like.
It's a multi-universe of options and you are only limited by your (and our) imagination! Have fun!
