Use navbar from a different theme

Is there a simple way to incorporate the navbar from a different theme within your site?
For example I would like to try incorporating the header nav from antimatter into my learn2-based theme, so that there is a header nav for different sites always present at the top of the page

Of course anything is possible, but this is going to require some HTML/CSS skills. It really is not a Grav-specific question, it's merely a web dev question. If that level of CSS work is beyond you, you might need to hire a developer because it's not a simple answer or a trivial process.

That's cool I can work out a way to do it. Was just checking if there was a 'quick win' first
