Ok, I am on the right lines. I added this to my additional.css

.navbar {
    position: fixed;
    width: 97.6%;
    z-index: 1;
}

It kinda works in a comical way.. The thing that escapes me is how should it know where the top of the screen is?
Scrolling the page leaves it exactly where it was, but when I scroll to the top of the page, it should stop and then fix itself there...

Good fun so far...
