Text to right of header

is it that page – correlating to your avatar ;)
You like to have to the right side of your logo a text – maybe like here on the board itself. And maybe on scroll the same effect ?

Sorry – i didn’t recognized it is divi on that page. – then a link would be nice.

PS: The board here did it with subtext –
f.e.: you can use any html here but you can use site name and description for it.
this for child-theme functions.php:

add_filter('avf_logo_subtext', 'kriesi_logo_addition');
function kriesi_logo_addition($sub)
{
  $sub .= "<span class='logo-title'>";
  $sub .= get_bloginfo( 'name', 'display' );
  $sub .= "</span>";
  $sub .= "<span class='logo-title logo-subtitle'>";
  $sub .= get_bloginfo( 'description', 'display' );
  $sub .= "</span>";
  return $sub;
}

Rest will be quick css work
