Full Width header image

What theme are you using?

I’m currently using the Pitch theme.

The theme forum would be a better place to post:

Looks like you’ll probably need to make a child theme and modify the header.php file so that the header area is outside the HTML structure limiting the width –

Thanks I’ll post this on the Themes forum.
