adding extra info to the logo container

Hey,

There is a lot of space left if you allign logo to the left, so I wonder if its possible to stick another div there… lets say with a custom text?

with something like this?

//text to header
function add_custom_text() {
?>
<div class=”custom_text”>helping you help others</div>
<?php
}
add_action(‘??????’, ‘add_custom_text’, 10, 0);
