What is Shopify Horizon? The Future of Theme Development
Discover Shopify Horizon, the revolutionary theme system that's replacing Dawn with AI-powered block generation and unprecedented flexibility for store customization.

What is Shopify Horizon? The Future of Theme Development
Shopify Horizon represents a fundamental shift in how Shopify themes work. Rather than being a single theme, Horizon is a flexible foundation that powers 10 distinct theme presets, each sharing the same underlying codebase but offering dramatically different visual appearances.
The 10 Horizon Presets
- Atelier: Editorial, magazine-style layouts perfect for content-rich brands
- Fabric: Clean, product-focused design ideal for fashion and lifestyle brands
- Dwell: Warm, homely aesthetic great for home goods and crafts
- Plus 7 additional presets covering various industries and aesthetics
Think of Horizon as a character in a game with 10 different skins—same abilities and power level, but each preset creates a totally different visual experience.
Why Horizon Matters: Dawn's Evolution
Horizon is replacing Dawn as Shopify's default theme. Here's what makes it revolutionary:
The Problems with Traditional Themes
- Rigid structure: Moving elements required code knowledge
- Limited customization: Stuck with predetermined layouts
- Time-consuming changes: Simple modifications took hours
Horizon's Solution
- Complete flexibility: Rearrange any element without code
- AI-powered creation: Generate custom blocks through simple descriptions
- Nested block system: Create complex layouts up to 8 levels deep
- Visual editing: See changes in real-time as you build
Bottom line: The new system eliminates the bottleneck of requiring code changes for smaller layout modifications, speeding up the entire design iteration process.
Understanding Theme Blocks
The Lego Principle
Theme blocks work like digital Lego pieces. Each block serves a specific purpose—headers, product grids, testimonials, banners—but unlike traditional themes, you can combine these in creative ways based on your business needs.
Dawn's accordion was limited to simple text answers. With Horizon, each accordion item can contain a number of different blocks.
Dawn vs Horizon Comparison
Dawn Accordion (Limited)

- Simple text-only answers
- Fixed structure
- No customization options
Horizon FAQ (Flexible)
- Multiple block types within each item
- Unlimited combinations possible
- Can include videos, images, forms, and AI-generated blocks
In the Horizon example, we can see that recommended products have been added into the accordion, but there are unlimited combinations available.
AI Block Generation Explained
The Game-Changing Feature
Horizon includes AI block generation, allowing you to create custom blocks for your specific needs. You describe what you want and AI creates it.
How AI Generation Works
Step 1: Describe Your Vision
- "Create a product comparison table with checkmarks and pricing columns"
- "Build a testimonial slider with star ratings and customer photos"
- "Generate a FAQ section with expandable answers"
Step 2: AI Generates Functional Code
- HTML structure
- CSS styling
- Interactive functionality
- Schema with settings
Step 3: Visual Customization
Use Horizon's visual editor to adjust settings:
- Colors and fonts
- Spacing and sizing
- Layout and positioning
- Content and imagery
Step 4: Iterative Improvements
Send follow-up instructions:
- "Make the buttons larger"
- "Change the color scheme to match my brand"
- "Add animation effects"
AI Prompt Examples
Effective Prompts (Detailed & Specific):
✅ "Create a customer review section with 5-star ratings, customer photos, verified purchase badges, review filtering by star rating, and a prominent 'Write a Review' button with modal popup"
✅ "Build a product grid with 4 columns on desktop, 2 on tablet, hover effects showing quick-view and add-to-cart buttons, sale badges for discounted items, and lazy loading for performance"
✅ "Generate a hero banner with background video, overlay text with fade-in animation, two call-to-action buttons (primary 'Shop Now' and secondary 'Learn More'), and responsive text sizing for mobile"
Less Effective Prompts (Too Basic):
❌ "Create a review section"
❌ "Add a product grid"
❌ "Make a hero banner"
Getting Started with Horizon
Step 1: Shift Your Mindset
Old thinking: "I need to find the perfect theme"
New thinking: "I'll build my perfect store using flexible components"
This mental shift is crucial. You're not shopping for a finished product; you're acquiring building materials.
Step 2: Choose Your Starting Point
Visit the Shopify Theme Store and explore Horizon presets. Don't overthink this choice—you can completely transform any preset using blocks.
Quick Selection Guide:
- E-commerce focused: Start with Fabric
- Content-heavy brands: Try Atelier
- Cozy, personal brands: Consider Dwell
- Unsure: Pick any—you'll customize it anyway
Step 3: Explore Theme Blocks
Get familiar with your building materials:
1. Understand block nesting - See how blocks fit inside other blocks
2. Test block combinations - Try different blocks together on a test page
3. Explore block settings - Check what customization options each block offers
4. Note what's missing - Identify gaps where AI generation might be needed
Step 4: Start with Simple AI Experiments
Begin with basic requests to understand the system:
1. First experiment: "Create a simple banner with my store name and a call-to-action button"
2. Second experiment: "Build a three-column feature section highlighting our top benefits"
3. Third experiment: "Generate a customer review section with star ratings"
Step 5: Learn Through Exploration
Dedicate time to experimentation:
- Try different block combinations
- Test AI generation with various prompts
- Explore nested block possibilities
- Study how successful stores use Horizon
My Recommendation
After exploring Horizon extensively, it's clear this represents the new standard and will be the main supported theme system moving forward. The combination of visual flexibility and AI-powered customization democratizes advanced store design in ways we haven't seen before.
If you're starting a new store or planning a major redesign, Horizon should be your default choice. The initial time investment in learning the system pays dividends in long-term flexibility and reduced dependence on developers.
