Website Design System
Rules and patterns for the Envilder website's pure CSS design system.
When to Use
- Creating new Astro components or page sections
- Adding or modifying CSS (global or scoped)
- Choosing between existing utility classes
- Defining new CSS variables
- Reviewing PRs that touch website styling
Themes
The site uses data-theme attribute on <html>. Two themes are supported:
| Theme | Selector | Palette |
|---|
| Retro (default) | :root | Game Boy green |
| Light | [data-theme="light"] | Warm neutrals |
Rules
- All colors MUST use CSS variables: never hardcode hex values
- New variables MUST be defined in both
:root (retro) and
[data-theme="light"] blocks in global.css
- Never modify the theme switcher mechanism or its localStorage key
color: var(--color-text);
background: var(--color-bg);
color: #8bac0f;
background: #1a1a2e;
Responsive Breakpoints
Mobile-first approach. Default styles target mobile; expand with min-width.
| Breakpoint | Target | Pattern |
|---|
| Default | Mobile | Single column, compact spacing |
min-width: 640px | Tablet | 2-column grids, expanded spacing |
min-width: 1024px | Desktop | 3-4 column grids, full layout |
Grid Utilities
Use existing grid classes: .grid-2, .grid-3, .grid-4.
Spacing & Layout
Use the spacing scale defined in global.css:
- Variables:
--space-xs through --space-4xl
- Container max-width:
--max-width (1200px)
Typography
| Use | Font | Access |
|---|
| Section titles / pixel style | Press Start 2P | Via .pixel-card h3 or custom class |
| Body text | Inter | Default (inherited) |
| Code / terminal | JetBrains Mono | <code>, <pre>, or mono class |
- Use
clamp() for fluid typography
- Never use fixed
px font sizes
Component Patterns
Reuse existing CSS classes for visual consistency:
| Class | Purpose |
|---|
.pixel-card | Bordered cards with pixel corner notches |
.pixel-icon | Emoji with pixelated filter |
.pixel-shadow | 4px offset retro shadow |
.badge | Small label badges |
.pixel-divider | Section separator |
.scanlines | CRT overlay effect (use sparingly) |
.section | Standard section wrapper with vertical padding |
File Locations
| What | Where |
|---|
| Global CSS | src/website/src/styles/global.css |
| Components | src/website/src/components/*.astro |
| Layout | src/website/src/layouts/BaseLayout.astro |
Constraints
- DO NOT install CSS frameworks or UI libraries: use existing pure CSS
- DO NOT hardcode colors: always CSS variables from
global.css
- DO NOT use fixed pixel font sizes: use
clamp() or relative units
- DO NOT break existing responsive layouts when adding new sections
- DO NOT add JavaScript frameworks (React, Vue): Astro components +
<script> tags only
- ONLY add new CSS variables if defined in both theme blocks
