How to customize Single Page Header

Hello, you need to go to the General Options > Page Title section of the customizer to customize the page header.

Thanks, but I would like to customize it more, I want to add my own text, etc.
Can you please tell me the file that I need to modify?
Thanks!

Hi, do you want to change the title for your entire website or only on single post?

Hi, i would like to change it for the whole website.

Take care.

Hi, okay, use this code in the functions.php file of your child theme:

function my_alter_page_header_title( $title ) {
 
    $title = 'Custom Title';
 
    // Return the title
    return $title;
    
}
add_filter( 'ocean_title', 'my_alter_page_header_title', 20 );
