Issues with Sticky Transparent Header

I’ve seen and read through the other posts related to header issues but not seen any solutions from the developer.

I’m currently exploring other options because it seems these issues have existed for some time and haven’t been addressed.

Like others, the notification bar is not playing nice with my sticky / transparent header. Would love someone to explain how to add the css necessary to keep them both where they should be. On initial load things seem fine but after scrolling the notification bar covers the header.
