I am attaching a screenshot of what I want to achieve in the “Private Content.”
I believe the trick is to get <?php get_template_part('headers/header-structure', $hstrucutre); ?> to show up before “st-pusher” (<div class="st-pusher" style="background-color:#fff;">).
However, when I edit “header.php” and put <?php get_template_part('headers/header-structure', $hstrucutre); ?> before <div class="st-pusher" style="background-color:#fff;"> then the header shows up over the mobile navigation / menu and blocks it.
I’ve solved it temporarily by specifying the “background-color” for “.main-header” in my custom.css file.
