Header is not full width on pages and posts

I have managed to get the content to be full width on pages and posts but not the header image. It makes no difference what size the header image is, if I add it through customize or use custom header plug-in etc. Can you advise what I should be doing.
Examples:


Hello @nobeatenpath,

Please try to use the following CSS code.

You can add CSS code in DashboardAppearanceCustomizeAdditional CSS (WordPress 4.7 and up). Also you can add CSS code directly to style.css file of your child theme.

.header-inner {
    width: 100%;
}

Please feel free to ask any other questions that you might have.

Kind Regards, Roman.

Perfect! Thanks for getting back to me so quickly

And have a nice day!

Kind Regards, Roman.
