[Theme: Customizr] Header Width and Alignnemnt

Hi, I am trying to make my theme’s header to be the fixed width, I have found a snippet

@media all and (min-width: 1080px) and (max-width: 1920px) {
.tc-header {
width: 1170px;
margin: 0 auto;
}

however the issue with this is it makes the header move to the right side, and I need it to be centered also, it the code makes header background same size as the header, leaving white on the side. I want it to look like the footer, header to be same size as the footer widget area, and have the background stretched full screen. Any help would be appreciated.

Thanks in advance
