this is a text box  - this test page has no header, (but it seems to have a menu bar - which LOOKS like a header to me)  I cannot change the color in the menu bar on this page.
xyz
abc
a 'divider' was placed below the text box

---

this is another text box, set inside a different "section" - the section needs "elements" inside it, thus, this text box.
xyz
another "section" is placed below, with nothing in the "drag elements here" space
