755# Astral Design System Integration
> Design reference for incorporating astral.sh visual elements into Astro Blue Documentation
## Overview
This document catalogs key design elements from [astral.sh](https://astral.sh) and provides guidance for integrating them into our Starlight-based documentation theme. The astral.sh design combines bold typography, vibrant accent colors, and distinctive geometric patterns to create a modern, tech-forward aesthetic.
**Current Theme Alignment**: Our existing theme already uses similar colors (dark purple, lime green accent in dark mode), making astral.sh elements a natural evolution rather than a complete redesign.
---
## Color System
### Primary Colors
```css
/* Dark Purple - Brand Primary */
--astral-purple-dark: rgb(43, 27, 52); /* #2B1B34 - Headers, footers, CTA sections */
--astral-purple-deeper: rgb(38, 18, 48); /* Already in theme as --astral-primary */
/* Lime Green - Vibrant Accent */
--astral-lime: rgb(215, 255, 100); /* #D7FF64 - Already in theme! */
--astral-lime-muted: rgb(190, 230, 80); /* Slightly less vibrant variant */
/* Sage/Olive Green - Secondary Accent */
--astral-sage: rgb(130, 139, 113); /* Product cards, subtle backgrounds */
--astral-olive-dark: rgb(107, 115, 94); /* Darker sage for depth */
```
### Background & Neutral Colors
```css
/* Backgrounds */
--astral-cream: rgb(242, 240, 235); /* Main page background */
--astral-beige-light: rgb(248, 246, 242); /* Subtle variation */
--astral-white: rgb(255, 255, 255); /* Card backgrounds */
/* Text & Borders */
--astral-text-dark: rgb(20, 20, 20); /* Primary text */
--astral-text-medium: rgb(100, 100, 100); /* Secondary text */
--astral-border-light: rgba(0, 0, 0, 0.08); /* Subtle borders */
```
### Implementation Notes
- **Existing match**: Our `--astral-primary-light` (lime green) already matches astral.sh accent
- **New additions**: Cream/beige backgrounds, sage green for product-style cards
- **Dark mode**: Keep existing dark mode purple/lime scheme
---
## Typography
### Font System
**Primary Font**: Inter (or system sans-serif fallback)
- Clean, modern, highly readable
- Wide range of weights available
### Type Scale & Styles
```css
/* Hero Headings - Bold Impact */
.hero-heading {
font-size: clamp(3rem, 8vw, 6rem);
font-weight: 700;
line-height: 1.1;
letter-spacing: -0.02em;
text-transform: uppercase; /* "NEXT-GEN PYTHON TOOLING" */
}
/* Section Headings */
.section-heading {
font-size: clamp(2rem, 4vw, 3rem);
font-weight: 600;
line-height: 1.2;
letter-spacing: -0.01em;
}
/* Small Caps Labels */
.label-caps {
font-size: 0.75rem;
font-weight: 600;
letter-spacing: 0.08em;
text-transform: uppercase; /* "RUFF", "ANNOUNCEMENTS" */
color: var(--astral-text-medium);
}
/* Body Text */
.body-large {
font-size: 1.125rem;
line-height: 1.7;
font-weight: 400;
}
```
### Typography Patterns Observed
1. **All-caps for emphasis**: Used sparingly but effectively (hero text, labels)
2. **Bold hierarchy**: Heavy weights (600-700) for headings
3. **Generous line-height**: Similar to our existing theme (1.75 for body)
4. **Tight letter-spacing on headings**: Creates modern, compact feel
---
## Geometric Pattern System
### Signature Design Element: Pixelated Shapes
The most distinctive astral.sh element is the **lime green pixelated/blocky pattern** used decoratively throughout the site.
#### Pattern Characteristics
- **Style**: Square/rectangular blocks arranged in organic, flowing shapes
- **Color**: Lime green (#D7FF64)
- **Usage**:
- Behind hero text as abstract shapes
- Corner decorations on cards/sections
- Diagonal stripe patterns for visual interest
#### Pattern Types
**1. Diagonal Stripe Pattern**
```
Appearance: Repeating diagonal lines in lime green
Usage: Card corners, section accents
Implementation: Can use CSS gradients or SVG pattern
```
**2. Blocky Organic Shapes**
```
Appearance: Pixel-art style abstract forms
Usage: Hero section background, large decorative elements
Implementation: SVG shapes or CSS grid-based patterns
```
### Implementation Approaches
**Option A: SVG Patterns (Recommended)**
```html
<!-- Define reusable SVG pattern -->
<svg class="pattern-defs">
<defs>
<pattern id="diagonal-stripes" width="20" height="20" patternUnits="userSpaceOnUse">
<rect width="10" height="20" fill="var(--astral-lime)" transform="rotate(45)" />
</pattern>
</defs>
</svg>
<!-- Use pattern as background -->
<div class="card-accent" style="background: url(#diagonal-stripes)"></div>
```
**Option B: CSS-Only Patterns**
```css
.pattern-diagonal {
background: repeating-linear-gradient(
45deg,
var(--astral-lime) 0px,
var(--astral-lime) 10px,
var(--astral-purple-dark) 10px,
var(--astral-purple-dark) 20px
);
}
```
**Option C: Custom SVG Graphics**
```
Create custom blocky shapes in Figma/Illustrator
Export as optimized SVG
Use as positioned background images
```

height: 100%;
background: rgba(215, 255, 100, 0.3);
border-radius: 4px;
}
```
---
## Layout Patterns
### Full-Width Sections
astral.sh uses full-width colored sections to create visual rhythm and hierarchy.
```css
.section-full {
width: 100%;
padding: 6rem 2rem;
}
.section-purple {
background: var(--astral-purple-dark);
color: white;
}
.section-cream {
background: var(--astral-cream);
}
.section-sage {
background: var(--astral-sage);
color: white;
}
.section-content {
max-width: 1200px;
margin: 0 auto;
}
```
### Spacing System
```css
/* Generous whitespace following astral.sh patterns */
--spacing-xs: 0.5rem; /* 8px */
--spacing-sm: 1rem; /* 16px */
--spacing-md: 2rem; /* 32px */
--spacing-lg: 4rem; /* 64px */
--spacing-xl: 6rem; /* 96px */
--spacing-2xl: 8rem; /* 128px */
/* Section spacing */
.section {
padding-block: var(--spacing-xl);
}
/* Component spacing */
.card {
padding: var(--spacing-lg);
}
.button {
padding: var(--spacing-sm) var(--spacing-md);
}
```
### Header Design
```css
.site-header {
position: sticky;
top: 0;
background: var(--astral-cream);
border-bottom: 1px solid var(--astral-border-light);
padding: 1rem 2rem;
z-index: 100;
}
.header-content {
max-width: 1400px;
margin: 0 auto;
display: flex;
justify-content: space-between;
align-items: center;
}

## Integration with Current Theme
### What Already Matches
Our existing theme (`src/styles/custom.css`) already includes:
✅ **Purple color scheme** - `--astral-primary: rgb(38, 18, 48)`
✅ **Lime green accent** - `--astral-primary-light: rgb(215, 255, 100)`
✅ **Clean typography** - Generous line-height (1.75), modern sans-serif
✅ **Minimal design** - Inspired by Mintlify/PYX, similar philosophy
✅ **Dark mode support** - Lime green accent in dark mode
### What Would Be New
🆕 **Geometric patterns** - Pixelated shapes, diagonal stripes
🆕 **Cream/beige backgrounds** - Currently uses pure white/gray
🆕 **Product card style** - Large colored cards with decorative patterns
🆕 **Badge components** - Version/status indicators
🆕 **Full-width sections** - Alternating colored backgrounds
🆕 **All-caps typography** - Hero headings, labels
🆕 **Performance charts** - Terminal-style code blocks with bars
### CSS Variables to Add
```css
:root {
/* Extend existing palette */
--astral-cream: rgb(242, 240, 235);
--astral-sage: rgb(130, 139, 113);
--astral-lime-muted: rgb(190, 230, 80);
/* Typography */
--font-heading-hero: 700;
--font-label-caps: 600;
--letter-spacing-caps: 0.08em;
/* Spacing (if not already defined) */
--spacing-xl: 6rem;
--spacing-2xl: 8rem;
}
```

## Implementation Approach
### Phase 1: Foundation (CSS-Only)
**Low effort, high impact changes**
1. Add new color variables (cream, sage, lime-muted)
2. Create button component styles (primary, secondary, tertiary)
3. Add badge/label utility classes
4. Implement spacing system adjustments
**Files to modify:**
- `src/styles/custom.css` - Add variables and component styles
### Phase 2: Components (Astro Components)
**Medium effort, adds new capabilities**
1. Create `Badge.astro` component for version/status indicators
2. Create `ProductCard.astro` for feature showcases
3. Create `AnnouncementBar.astro` for top-of-page announcements
4. Create `PerformanceChart.astro` for benchmarks/comparisons
**Files to create:**
- `src/components/Badge.astro`
- `src/components/ProductCard.astro`
- `src/components/AnnouncementBar.astro`
- `src/components/PerformanceChart.astro`
### Phase 3: Patterns (SVG + CSS)
**Higher effort, distinctive visual elements**
1. Create SVG pattern library
- Diagonal stripes
- Pixelated organic shapes
- Corner accents
2. Implement pattern system in CSS
3. Add pattern backgrounds to cards/sections
**Files to create:**
- `src/assets/patterns/diagonal-stripes.svg`
- `src/assets/patterns/blocky-shape-1.svg`
- `src/styles/patterns.css`
### Phase 4: Layout Enhancements
**Larger structural changes**
1. Implement full-width section system
2. Add alternating background colors
3. Create hero section layouts
4. Enhance header with announcement bar
**Files to modify:**
- `astro.config.mjs` - Enable full-width layouts
- `src/components/Header.astro` - Add announcement bar
- Create new layout components for landing pages

## Priority Recommendations
### High Priority (Quick Wins)
These provide immediate visual improvement with minimal effort:
1. **Add cream background option** - Single CSS variable
2. **Create badge component** - Simple, reusable, valuable for docs
3. **Implement button styles** - Better CTAs throughout docs
4. **Add all-caps labels** - CSS utility class for section headers
### Medium Priority (Enhanced Polish)
Moderate effort with strong visual impact:
1. **Product card component** - Great for feature pages
2. **Announcement bar** - Highlight important updates
3. **SVG diagonal stripe pattern** - Subtle decoration
4. **Performance chart component** - Useful for benchmarks
### Lower Priority (Nice to Have)
Higher effort, primarily aesthetic:
1. **Custom blocky SVG shapes** - Distinctive but time-intensive
2. **Full-width section system** - Requires layout changes
3. **Testimonial card component** - Limited use in technical docs
4. **Header redesign** - Current header is functional

Next-Gen
<span class="text-accent">Documentation</span>
</h1>
<div class="hero-actions">
<a href="/getting-started" class="button-primary">Get Started</a>
<a href="/docs" class="button-tertiary">Browse Docs</a>
</div>
</div>
<!-- Decorative pattern background -->
<div class="pattern-background" aria-hidden="true"></div>
</section>
```
### Feature Showcase
```astro
---
import ProductCard from '../components/ProductCard.astro';
import Badge from '../components/Badge.astro';
---
<ProductCard color="sage" icon="/icons/feature.svg" label="Performance" pattern="diagonal">
