The nav bar is surrounding by a header element and can’t expand the full width of the page.

So you can color the nav elements background only without getting into more advanced CSS that’s needs to be tinkered with.

You can see this by using a custom-css setting and the following Band-aid CSS:

nav.header__inline-menu {
    width: 100%;
    margin: 0 auto;
    text-align: center;
    background-color: red;
}
