Templates

Templates control what's rendered on each type of page in a theme.

The Skeleton Theme scaffolds JSON templates to make it easy for merchants to customize their store.

None of the template types are required, and not all of them are included in the Skeleton Theme. Refer to the template types reference for a full list.

Sections

Sections are Liquid files that allow you to create reusable modules of content that can be customized by merchants. They can also include blocks which allow merchants to add, remove, and reorder content within a section.

Sections are made customizable by including a {% schema %} in the body. For more information, refer to the section schema documentation.

Blocks

Blocks let developers create flexible layouts by breaking down sections into smaller, reusable pieces of Liquid. Each block has its own set of settings, and can be added, removed, and reordered within a section.

Blocks are made customizable by including a {% schema %} in the body. For more information, refer to the block schema documentation.

Schemas

When developing components defined by schema settings, we recommend these guidelines to simplify your code:

• Single property settings: For settings that correspond to a single CSS property, use CSS variables:

  <div class="collection" style="--gap: {{ block.settings.gap }}px">
    ...
  </div>
  
  {% stylesheet %}
    .collection {
      gap: var(--gap);
    }
  {% endstylesheet %}
  
  {% schema %}
  {
    "settings": [{
      "type": "range",
      "label": "gap",
      "id": "gap",
      "min": 0,
      "max": 100,
      "unit": "px",
      "default": 0,
    }]
  }
  {% endschema %}
  

• Multiple property settings: For settings that control multiple CSS properties, use CSS classes:

  <div class="collection {{ block.settings.layout }}">
    ...
  </div>
  
  {% stylesheet %}
    .collection--full-width {
      /* multiple styles */
    }
    .collection--narrow {
      /* multiple styles */
    }
  {% endstylesheet %}
  
  {% schema %}
  {
    "settings": [{
      "type": "select",
      "id": "layout",
      "label": "layout",
      "values": [
        { "value": "collection--full-width", "label": "t:options.full" },
        { "value": "collection--narrow", "label": "t:options.narrow" }
      ]
    }]
  }
  {% endschema %}
  

CSS & JavaScript

For CSS and JavaScript, we recommend using the {% stylesheet %} and {% javascript %} tags. They can be included multiple times, but the code will only appear once.

critical.css

The Skeleton Theme explicitly separates essential CSS necessary for every page into a dedicated critical.css file.
