The tagline in Forever is generated through the file greeting.php.
The file greeting.php is called in via index.php, as you can see at line 160:
<?php
if ( is_home() && ! is_paged() ) {
get_template_part( 'greeting' );
get_template_part( 'recent-posts' );
}
?>
The firest thing you’ll need to do is set up a child theme, so your tweaks won’t be overwritten when updating the theme. Here are some guides in case you haven’t made one before:

Once your child theme is ready, make a copy of the file index.php from the parent theme and place it into the child theme folder.
Remove this line to un-display the tagline from the current spot.
get_template_part( 'greeting' );
Alternatively, you can “comment out” that line by adding two slashes in front of it:
//get_template_part( 'greeting' );
Leave the rest of that code intact.
Next, after line 22, add this new block of code to display the tagline after the header:
<?php
if ( is_home() && ! is_paged() ) {
get_template_part( 'greeting' );
}
?>
This puts the tagline just below your main menu.
If you want to put it immediately below your site title instead, you’ll also need to copy the file.php into your child theme – why not see if you can figure out how to add it there based on what you’ve learned so far. 🙂
