Adding Header to Pages

Hi All,

I am trying to add the same header to additional pages on my site http://www.nrcocp.com

I have inserted <?php include get_template_directory() . “/sections/big_title.php”; ?> into page.php and added the following to Custom CSS:

body {
background: url(“http://nrcocp.com/wp-content/uploads/2015/08/about-pic-2.jpg&#8221;) fixed !important;
}

However, the text in the header appears the same on all pages (e.g. About) and I would like to change it – for example, I want the text to say “About Us” on the header for the About page.

Is it possible to do this and if so, can you please advise.

Thanks in advance.
