Show Header on all pages?

Hi,
to show the header on all pages you need to remove line 37
if ( is_home() || is_front_page() ) {
and line 56
}
in the file header.php

To remove the site title, go to the customizer and uncheck the “show text in header” option.

To remove a title from a page format, it’s best to you create a new template:

Copy page.php and rename this copy to something distinctive.
At the top of the new file, inside the php tag, add:

/*
Template Name: Your template name of choice
/*

Then find and remove this line:
<h1 class="post-title"><?php the_title(); ?></h1>

Then activate the template for the page that you don’t want to display titles on.
