Hello...I never did "get" how to make the hamburger navigation properly...and now I would like the "hamburger" background to be clear or translucent. Is that possible?

Can someone make a video or give me explicit instructions so I can finally understand how to do this?

I'm so sorry to ask...but a medical condition does hamper me sometimes in remembering and "getting" what others are saying that are technical. Video is always welcome or pictures...I know I'm a pain..but I REALLY APPRECIATE you and your patience with me.

Here's the site I am presently working on...and it's ONLY the mobile version I need assistance with, PLEASE!

Thanks you, always!
