<p class="order-number"><?= $block->escapeHtml(__('Your order number is: %1.', sprintf('<strong>%s</strong>', $block->escapeUrl($block->getViewOrderUrl()), $block->getOrderId())), ['a', 'strong']) ?></p>

<p><?= $block->escapeHtml(__('Your order # is: <span>%1</span>.', $block->getOrderId()), ['span']) ?></p>
<?php endif;?>
<h5><?= $block->escapeHtml(__('Get 25% Off your next order')) ?></h5>
<p class="order-disc-details">When your friends use your referral code to place their first order,you'll both get <span class="off-percentage">25% Off</span>. It's a win win 🙂</p>
