# SimpleShop Theme Studio - Complete Implementation Summary
## Overview
This document summarises the complete Theme Studio feature developed for SimpleShop - an open-source POD (print-on-demand) e-commerce platform built with Phoenix/Elixir/LiveView. The Theme Studio allows sellers to customise their shop's appearance through a constrained but flexible system of presets and options.
## Design Philosophy
### Core Principles
1. **"One theme, infinite variations"** - Rather than offering multiple themes, we provide one solid foundation with curated customisation options
2. **Constrained creativity** - Limit choices to prevent poor design outcomes while maintaining perceived variety
3. **No professional photography required** - Defaults work well with product mockups, not just lifestyle imagery
4. **Mobile-first** - All features work on touch devices (no hover-only interactions)
5. **Ethical design** - No dark patterns like countdown timers or fake urgency
### Target Audience
- Solo POD creators (artists, illustrators, designers)
- Small catalogs (typically <50 products)
- Non-technical users who found WooCommerce too complex
- Budget-conscious sellers (£5-10/month target price)
## Feature Architecture
### Preset System
Nine curated presets that combine multiple settings into cohesive looks:
```elixir
@presets %{
gallery: %{
mood: "warm",
typography: "editorial",
shape: "soft",
density: "spacious",
grid: "3",
header: "centered",
accent: "#e85d04"
},
studio: %{
mood: "neutral",

## Data Model
### Theme Settings Schema
```elixir
defmodule SimpleShop.Shops.ThemeSettings do
use Ecto.Schema
import Ecto.Changeset
embedded_schema do
# Core preset (optional - if set, provides defaults)
field :preset, :string
# Branding
field :shop_name, :string
field :logo_mode, :string, default: "text-only"
field :logo_url, :string
field :logo_size, :integer, default: 36
field :logo_recolor, :boolean, default: false

field :header_position_x, :integer, default: 50
field :header_position_y, :integer, default: 50
# Theme tokens
field :mood, :string, default: "neutral"
field :typography, :string, default: "clean"
field :shape, :string, default: "soft"
field :density, :string, default: "balanced"
field :accent_color, :string, default: "#f97316"

field :quick_add, :boolean, default: true
field :show_prices, :boolean, default: true
field :pdp_trust_badges, :boolean, default: true
field :pdp_reviews, :boolean, default: true
field :pdp_related_products, :boolean, default: true
end
end
```
### CSS Custom Properties
The theme system uses CSS custom properties for real-time updates. Key variables:
```css
/* Primitives (fixed) */
--p-space-1 through --p-space-24
--p-radius-none through --p-radius-full
--p-font-inter, --p-font-fraunces, etc.
--p-text-xs through --p-text-4xl
/* Theme tokens (dynamic) */
--t-surface-base, --t-surface-raised, --t-surface-sunken
--t-text-primary, --t-text-secondary, --t-text-tertiary
--t-border-default, --t-border-subtle
--t-accent (HSL-based for easy manipulation)
--t-font-heading, --t-font-body
--t-heading-weight, --t-heading-tracking
--t-radius-button, --t-radius-card, --t-radius-input
--t-density (multiplier)
/* Semantic aliases */
--color-page, --color-card, --color-heading, --color-body
--font-heading, --font-body, --weight-heading
--space-xs through --space-2xl
--radius-button, --radius-card
```
## LiveView Implementation Notes
### Real-time Preview
The theme editor should provide instant visual feedback. In Phoenix LiveView:
```elixir
defmodule SimpleShopWeb.ThemeEditorLive do
use SimpleShopWeb, :live_view
def mount(_params, _session, socket) do
{:ok, assign(socket,
settings: default_settings(),
preview_page: "home"
)}
end
def handle_event("update_setting", %{"key" => key, "value" => value}, socket) do
settings = Map.put(socket.assigns.settings, String.to_atom(key), value)
{:noreply, assign(socket, settings: settings)}
end
def handle_event("apply_preset", %{"preset" => preset_name}, socket) do
preset = Map.get(@presets, String.to_atom(preset_name))
settings = Map.merge(socket.assigns.settings, preset)
{:noreply, assign(socket, settings: settings)}
end
def handle_event("change_preview_page", %{"page" => page}, socket) do
{:noreply, assign(socket, preview_page: page)}
end
end
```
### CSS Generation
Generate CSS custom properties from settings:
```elixir
defmodule SimpleShop.Theme.CSSGenerator do
def generate_css(settings) do
"""
:root {
--t-accent-h: #{accent_hue(settings.accent_color)};
--t-accent-s: #{accent_saturation(settings.accent_color)}%;
--t-accent-l: #{accent_lightness(settings.accent_color)}%;
/* ... other properties */
}
#{mood_css(settings.mood)}
#{typography_css(settings.typography)}
#{shape_css(settings.shape)}
#{density_css(settings.density)}
"""
end
end
```
## File Uploads
### Logo Upload
- Accepted formats: PNG, JPG, WebP, SVG
- Max size: 2MB recommended
- SVG special handling: Store raw content for recolouring feature
- Storage: Local or S3-compatible (user's choice for data sovereignty)
### Header Image Upload
- Accepted formats: PNG, JPG, WebP
- Max size: 5MB recommended
- Responsive serving: Generate multiple sizes
## Preview Pages
The demo includes 7 preview pages to show theme in context:
1. **Home** - Hero, categories, featured products, testimonials
2. **Collection** - Product grid with filters
3. **Product (PDP)** - Gallery, details, add to cart, reviews
4. **Cart** - Line items, totals, checkout button
5. **About** - Brand story, values
6. **Contact** - Contact form, details
7. **Error (404)** - Error state styling
## Research Findings: POD Theme Best Practices
### What POD Sellers Actually Use
- **Free themes dominate**: Dawn, Spotlight, Studio most popular
- **Premium choice**: Streamline ($350) best for growing POD brands
- **Impulse** is fashion-focused, not ideal POD default
### Key Requirements for POD
1. Large product imagery (mockups need to shine)
2. Clean/minimal design (products are the focus)
3. Quick setup (non-technical users)
4. Mobile-responsive (60%+ traffic)
5. Works with small catalogs
6. No reliance on lifestyle photography
### What to Avoid
- Countdown timers (dark pattern)
- Complex promotional systems
- Hover-only interactions
- Features requiring professional photography
- Enterprise complexity
## Recommended Next Steps for Phoenix Implementation
### Phase 1: Core Theme System
1. Create ThemeSettings schema and migrations
2. Build CSS generator module
3. Implement preset system
4. Create basic LiveView editor with sidebar controls
### Phase 2: Branding
1. Logo upload with LiveView uploads
2. SVG parsing and recolouring
3. Header image with positioning controls
### Phase 3: Preview System
1. Live preview component
2. Page switching (home/collection/product/etc.)
3. Mock data for preview products
### Phase 4: Persistence
1. Save to shop record
2. Apply to storefront templates
3. CSS caching strategy
## Prototype File
The complete working HTML prototype is available at:
- `/home/claude/theme-demo-v28.html`
- `/mnt/user-data/outputs/theme-demo-v28.html`
This 6,277-line file contains all CSS, HTML structure, and JavaScript logic that can be referenced when building the Phoenix/LiveView implementation.
## Combination Count
With current options, the system offers:
- 4 moods × 7 typographies × 4 shapes × 3 densities × 3 grids × 3 headers = **3,024 base combinations**
- Plus accent colours, layout width, button styles, shadows, etc.
- Marketing claim: "100,000+ possible combinations"
