Although it's rare for header nav items to wrap they can and this would overlap and obscure page content. This only occurs on the desktop responsive mode. This one-liner fix prevents wrapping because our layout doesn't support wrapping anyway. This fixes #7920.

In the following screenshots I modified the template to add the text "wrapping" to trigger the bug more easily.

The header (
<nav>) and page content (<main>) are in separate CSS flow layouts because the header isposition:fixedso when the header wraps it can't push the page content down. They only appear to be adjacent due to thenavbar-offsetCSS on<body>.This wrapping bug can be caused in several ways
This CSS fix could cause horizontal scrolling but it doesn't for me, and that seem preferable to obscuring the page content.
I considered another approach to allow wrapping and use JS to measure the height of the header (repeatedly as the user may resize their browser) and use the header height to set the
navbar-offsetbut that seemed unnecessarily complicated.You may be asking yourself whether this is a lot of text for a one-liner fix, and yes — yes it is. You're welcome.
