Liquid

Liquid is the templating language YouCan themes are built with. It lets you mix static HTML with logic and store data, so a theme can render a different page for every product, collection, or cart without writing a line of application code.

<h1>{{ product.name }}</h1>

{% if product.available %}
  <span>{{ product.price | money }}</span>
{% else %}
  <span>{{ 'product.sold_out' | t }}</span>
{% endif %}

Building blocks

Objects	Store data you can output or loop over, like product or cart.
Tags	Logic that controls a template: conditionals (if, unless, case), loops (for), and helpers (form, paginate, render). Browse the full list under Developer Tools ▸ Liquid ▸ Tags in the sidebar.
Filters	Functions applied to a value with the pipe (|) character, for formatting and transforming output, for example {{ product.price | money }}. Browse the full list under Developer Tools ▸ Liquid ▸ Filters in the sidebar.
Basics	The primitive types and operators Liquid expressions are built from.

Where Liquid runs

Liquid renders layouts, templates, sections, and snippets. Which objects are available depends on where you are: some, like cart and settings, are global; others, like product, only exist on the template they belong to. Each template type page documents the objects it receives.
