Based on the doc, I tested your code and below you can find a simple version of html, change it based on your need. For the view you should remove page_kwarg = 'posts'. Make sure that you have more post objects than 3!

{% for post in page_obj %}
    {{ post.title }}<br>
{% endfor %}

<div >
    <span >
        {% if page_obj.has_previous %}
            <a href="?page=1">&laquo; first</a>
            <a href="?page={{ page_obj.previous_page_number }}">previous</a>
        {% endif %}

        <span >
            Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}.
        </span>

        {% if page_obj.has_next %}
            <a href="?page={{ page_obj.next_page_number }}">next</a>
            <a href="?page={{ page_obj.paginator.num_pages }}">last &raquo;</a>
        {% endif %}
    </span>
</div>
