Answer 1

It's possible to use django built-in widthratio template tag and add filter:

• add 5 to forloop.counter {{forloop.counter|add:5}}
• subtract 5 from forloop.counter {{forloop.counter|add:"-5"}}
• devide forloop.counter by 5 {% widthratio forloop.counter 5 1 %}
• multiply forloop.counter by 5 {% widthratio forloop.counter 1 5 %}
