Liquid is an open-source templating language that was developed by Shopify. It uses tags, objects, and filters to render out content into a theme.
For an in-depth Liquid reference, check out the official Liquid documentation. {: .tip}
A tag is a piece of logic that will tell the templating engine what to do. This includes operations like if, for, foreach, and capture. For example:
{% highlight liquid %} {% raw %} {% if page.title == 'Home' %} Do something if condition is true {% else %} Do something if condition is false {% endif %} {% endraw %} {% endhighlight %}
Note that each tag is ended with the same tag, prepended with end.
An object is a piece of data that has attributes with content. An object can be your site, a post, a set of posts, and so on. For example:
{% highlight liquid %} {% raw %} {{ page.title }} {% endraw %} {% endhighlight %}
Filters are used to modify the output of attributes (i.e., strings, numbers, variables, and objects):
{% highlight liquid %} {% raw %} {{ 'sales' | append: '.jpg' }}
{% endraw %} {% endhighlight %}
