Brine: full width navigation

I am having some issues with making the navigation go full width. Any help would be most appreciated.

In Design>Styles I have set branding position to Top Center and Primary Nav Position to Bottom Center. Also, I have a secondary navigation button that is set to Bottom Right.

All navigation tabs are where they should be, however the background color that I have set to white is not going to the left side of the primary navigation. See attached screenshot.

Here is my CSS code for the background color:/* primary nav bkgd colour */.Header-nav { width: 100%; height: 50px; background-color: white;
}

Thank you.

@zukdesign Can you share site url? Easy to check CSS!

I appreciate your help. I would prefer to share just the CSS. This is a passworded client site.

@zukdesign If you can't share here. You can send me a message via contact form on my blog.

Ok thanks, I have done that.

.Header-inner.Header-inner--bottom {
   background: #fff;
}

Perfect! Thank you so much! I tried a variation of all of those, I wasn't out by much.
