This step-by-step tutorial will help you build a fully responsive grid layout for collections or products — without apps, using lightweight Shopify theme coding.

You can use this for:

• Featured collections on the homepage
• Product recommendations
• Collection card grids
• Sale items / new arrivals section

✨ Final Output You Will Get

A responsive grid that:

• Shows 4 items on desktop
• Shows 2 items on tablets
• Shows 1 item on mobile

🧩 Step 1 — Create a New Section

Inside your Shopify admin:

1. Go to Online Store → Themes
2. Click Edit Code
3. Open Sections folder
4. Click Add a new section
5. Name it: responsive-grid.liquid

Paste the following code:

{% assign grid_items = section.settings.collection.products | default: section.settings.collection_list %}

{{ section.settings.heading }}

{% for product in section.settings.collection.products limit: section.settings.limit %}{% if product.featured_image %} {% endif %}

{{ product.title }}

{{ product.price | money }}

{% endfor %}

{% schema %}
{
  "name": "Responsive Collection/Product Grid",
  "settings": [
    {
      "type": "text",
      "id": "heading",
      "label": "Section Heading",
      "default": "Featured Products"
    },
    {
      "type": "collection",
      "id": "collection",
      "label": "Select Collection"
    },
    {
      "type": "number",
      "id": "limit",
      "label": "Max Products to Show",
      "default": 8
    }
  ],
  "presets": [
    {
      "name": "Responsive Grid Layout"
    }
  ]
}
{% endschema %}

🧩 Step 2 — Add Section to Your Theme

Now add it to a template:

1. Go to Online Store → Themes → Customize
2. Open your Home Page or any template
3. Click Add Section
4. Select Responsive Grid Layout

Choose a collection → Save.

🎉 You're Done!

You now have a fully responsive collection/product grid that automatically adapts to all screen sizes.

This setup is flexible, lightweight, and app-free — ideal for performance and customization.

If you'd like, I can also create:
