Gimp has a steep learning curve so stick at it. Best way to get to grips? Just keep experimenting, use the Gimp docs when required https://docs.gimp.org/2.10/en/
I can not see anything wrong with your procedure for a "Title bar" An alpha channel is just a mask that the display application uses to 'hide' part of the image. A customary way to display this is the checker pattern but not always, very much depends on the display application.
Here is the same image in three different programs: top displays white, middle checker, bottom (a web browser ) black.
Take your pick
Open the png image up again in Gimp. Does it have the checker pattern. Then it is ok. The real check is when you add to your web page.
Did you export to a png with a white background layer underneath? Exporting will flatten the image. Either turn the visibility of the background layer off or delete it leaving just the banner.

Quote:All well and good I thought. However, when I open the image it still has a white background! What am I doing wrong?
