All these replies, and none of them have mentioned why your original
approach doesn't work.

When iterating through a form in your template, each field instance
returned is not a field from form.fields, it is a BoundField that
represents the corresponding field from form.fields.

The original field object is available in bfield.field . Therefore,
with your original code, you can do this in the template:

   {% for bfield in form.visible_fields %}
       <div class="{{ bfield.field.div_css }}" >
       ....
       </div>
   {% endfor %}
