title: Change wc_empty_cart_message function in WooCommerce 3.1
body: <p>I've been trying to change my layout for the empty-cart message. I've removed the action, and try to replace it.</p>
  
  <p>I'd like to change the htm structure output from:</p>
  
  <pre><code>&lt;p class="empty-cart"&gt;&lt;/p&gt; 
  </code></pre>
  
  <p>to:</p>
  
  <pre><code>&lt;div class="col-12 offset-md-1 col-md-10"&gt;&lt;p class="empty-cart"&gt;&lt;/p&gt;&lt;/div&gt;
  </code></pre>
  
  <p>My actual code <em>(in functions.php file of my theme)</em>:</p>
  
  <pre><code>/** Change the output for empty-cart within a div */
  remove_action( 'wc_empty_cart_message', 'wc_empty_cart_message', 10 );
  add_action( 'wc_empty_cart_message', 'wc_empty_cart_message', 10 );
  
  function custom_wc_empty_cart_message() {
  echo '&lt;div class="col-12 offset-md-1 col-md-10"&gt;&lt;p class="cart-empty"&gt;'
  . wp_kses_post( apply_filters( 'wc_empty_cart_message', __( 'Your cart is currently empty.', 'woocommerce' ) ) ) . '&lt;/p&gt;&lt;/div&gt;';
  }
  </code></pre>
  
  <p>But this code doesn't work. Does anyone has a suggestions on how to make this work? </p>
