I have a modern communication site inside our SharePoint Online tenant, and we want to do the following modification to our top navigation area:-

  1. Change the background color to be dark blue

  2. Add a button on the top-right corner >> and when users click on this an external link will open.

Here is what we need to build:-

So can anyone advice how we can achieve the above 2 points?

An SPFx application customiser is limited to the top and bottom part of a page and does not change the out-of-the-box SharePoint navigation bar. Therefore, it wouldn't be possible to add the button.

Use page placeholders from Application Customizer (Hello World part 2)
