Bug of site variable

I have a code like this
--- html
{% for item in site.social %}
<li>
<a href="{{ item.url }}"><i class="fa fa-{{ item.icon }}"></i>
</a>
</li>
{% endfor %}

and in site.yaml I have 

social:
url:

• https://fr-fr.facebook.com/
• https://github.com/
  icon:
• facebook-square
• github
  TXTCopy

  
  and wen I refresh my webpage I have 2 <li>
  but the value of item.url and item.icon are empty
  

Your data is not structured correctly for that loop. You'd need something like:

social:
  - url: URL1
    icon: ICON1
  - url: URL2
    icon: ICON2
