Online store

Liquid & theme code

Open Online Store → Themes → Edit code. A theme has three kinds of files:

Path	Purpose
`sections/*.liquid`	A section merchants can add in the theme editor. Settings come from its {% schema %} block.
`snippets/*.liquid`	Reusable partials: {% render 'name', var: value %}.
`assets/custom.css`	Loaded on every storefront page after theme styles.
`assets/custom.js`	Runs once per page load (good place for custom pixels).

Section schema

Liquid

<section class="sf-page">
  <h2>{{ section.settings.heading }}</h2>
  {%- for block in section.blocks -%}
    <p>{{ block.settings.text }}</p>
  {%- endfor -%}
</section>

{% schema %}
{
  "name": "Testimonials",
  "settings": [{ "type": "text", "id": "heading", "label": "Heading", "default": "What customers say" }],
  "blocks": [{ "type": "quote", "name": "Quote", "settings": [{ "type": "textarea", "id": "text", "label": "Quote" }] }],
  "max_blocks": 6
}
{% endschema %}

Setting types: text, textarea, richtext, url, image, color, checkbox, range (min/max/step), select (options), collection, product, menu, page, header.

Rules

Liquid is sandboxed: no JavaScript execution, no access to object prototypes, render-time and memory limits. Errors show in the theme editor preview and render nothing on the live store.
Files are validated on save (Liquid syntax and schema JSON). Max 256 KB per file. Every save is versioned; restore from Versions.
Names: lowercase letters, numbers, - and _.
