not showing tagline

The tagline of this theme is showing on the Page Title (And I think It’s good enough for SEO). We didn’t design space to display Tagline on this theme. Let me know where you want to display the Tagline, I will suggest a solution for you.

To resolve this issue, you can open the header.php file. replace the following code (line 33 -> 47)

<div id="header">
    <div id="header-inner">
        <div id="branding">
            <h1 id="site-title">
                <a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a>
            </h1>
            </div>
        <div id="navigation">
            <div>
                <?php wp_nav_menu( array( 'theme_location' => 'primary', 'container' => false ) ); ?>
             </div>
        </div>
        <?php do_action( 'after-navigation' ); ?>
    </div>
</div>

With new code:

<div id="header">
    <div id="header-inner">
        <div id="branding">
            <h1 id="site-title">
                <a href="<?php echo esc_url( home_url( '/' ) ); ?>" title="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>" rel="home"><?php bloginfo( 'name' ); ?></a>
            </h1>
            <h2><?php bloginfo('description'); ?></h2>
        </div>
        <div id="navigation">
            <div>
                <?php wp_nav_menu( array( 'theme_location' => 'primary', 'container' => false ) ); ?>
             </div>
        </div>
        <?php do_action( 'after-navigation' ); ?>
    </div>
</div>
