Liquid templates: even/odd items in for loop

Question

If I have a for loop in Liquid (using Jekyll), how can I target even (or odd) items only? I have tried:

{% for item in site.posts %}
    {% if forloop.index

I think you'll want to use the cycle tag for this. For example:

{% for post in site.categories.articles %}
   

{% endfor %}

If you want different HTML markup for each cycle:

{% for item in site.posts %}
  {% capture thecycle %}{% cycle 'odd', 'even' %}{% endcapture %}
  {% if thecycle == 'odd' %}
    
echo something
  {% endif %}
{% endfor %}

You can find more information on it at Liquid for Designers, although the example there isn't particularly helpful. This Shopify support thread should also help.
