Hooking into the HTML header container

Question

I'm trying to hook into the header.php of wordpress theme(s) more specifically, right before the closing header tag </header>. I'd like to do this in a programmatic way so when I switch themes I don't have to remember to go include the method of a custom hook <?php my_cool_hook(); ?>

Is there a way to accomplish this? I've tried looking through the available actions but so far I haven't found any that would suite my needs.

Thanks.

Unless a theme provides such a hook there is no way to do this with actions and filters. If a hook is provided then it will be theme specific, no generic WP solution exists.

For a full list of the hooks that a theme should implement, see here:

https://developer.wordpress.org/themes/advanced-topics/plugin-api-hooks/

At the moment this includes:

• wp_head() Goes at the end of the element of a theme’s header.php template file.
• wp_body_open() Goes at the begining of the element of a theme’s header.php template file.
• wp_footer() Goes in footer.php, just before the closing tag
• wp_meta() Typically goes in the Meta section of a Theme’s menu or sidebar.
• comment_form() Goes in comments.php directly before the file’s closing tag ()

Note that aside from wp_head and wp_footer, there is no guarantee that the theme developer knew to add them, or did so correctly, particularly wp_body_open and wp_meta
