function education_hub_site_branding_override(){
    ?>
        <div class="site-branding">

            <?php if ( is_front_page() || is_home() ) : ?>
                <h1>
            <?php endif; ?>
            <?php education_hub_the_custom_logo(); ?>
            <?php if ( is_front_page() || is_home() ) : ?>
                </h1>
            <?php endif; ?>

            <?php $show_title = education_hub_get_option( 'show_title' ); ?>
            <?php $show_tagline = education_hub_get_option( 'show_tagline' ); ?>
