Modulus % in Django template

I'm looking for a way to use something like the modulus operator in django. What I am trying to do is to add a classname to every fourth element in a loop. With modulus it would look like this: {% for p in posts %} <div class="post width1 height2 column {% if forloop.counter0 % 4 == 0 %}first{% endif %}}"> <div class="preview"> </div> <div class="overlay"> </div> <h2>p.title</h2> </div> {% endfor %} Of course this doesn't work because % is a reserved character. Is there any other way to do this?
You need divisibleby, a built-in django filter. {% for p in posts %} <div class="post width1 height2 column {% if forloop.counter0|divisibleby:4 %}first{% endif %}"> <div class="preview"> </div> <div class="overlay"> </div> <h2>p.title</h2> </div> {% endfor %}
