Hamburger nav on all devices with transparent background.

Can you make sure it's turned on?

Yep! Thanks. That makes it show up. Now...is there anyway to get rid of the black box around it and to adjust it's position relative to the top of the page and the side of the page?

By the way, the hamburger only has a black box around it on the home page. Not on the about page.

Try changing the Parent Items color under Primary Navigation:

That was it! Thank you, Leo.

No problem :)
