Print magazines solved the hierarchy problem decades ago — drop caps pull you in, generous margins let the eye recover, and a serif–sans pairing signals "this is serious reading." This design system translates those same conventions into HTML and CSS, proving that editorial sophistication doesn't require a printing press.
1. Style Foundations (The "Atoms")
Foundational tokens and rules that sync design and code: colors, type, spacing, elevation, and iconography.
Design Philosophy
Content First
The design serves the content, not the other way around. Typography and layout choices prioritize readability and comprehension over decoration.
Editorial Heritage
Drawing from print magazine traditions—drop caps, pull quotes, generous margins—to create a premium reading experience on screen.
Systematic Flexibility
A consistent core system (typography, spacing, components) with accent color variations that give each project its own identity.
Quiet Sophistication
Avoiding trendy effects and AI-aesthetic clichés. The design feels timeless, professional, and distinctly human-crafted.
Color System
The palette is deliberately restrained. #f8f5f0 (Paper) was chosen over pure white because it reduces screen glare during long reading sessions — the same reason print magazines use off-white stock. The ink (#1a1a1a) is slightly softened from true black to avoid the harsh contrast that strains eyes. Each project gets a single accent color that acts like an editorial "highlight marker" — it brands the case study without overwhelming the content. The accent never touches body text; it's reserved for drop caps, labels, links, and interactive elements.
Core Palette
Five semantic colors form the foundation. These remain constant across all case studies.
Semantic Colors (Success, Warning, Error)
Use for feedback states, validation, and status indicators.
Neutral / Grayscale
Neutral scale for backgrounds, borders, and subtle hierarchy.
Project Accent Colors
Each case study has a unique accent color reflecting the project's brand or theme.
Design Tokens
Named variables (e.g. --color-brand-primary) keep design and code in sync. Use in CSS and
export to Figma/Sketch tokens.
Typography
Instrument Serif was chosen as the display face because it carries the authority of traditional editorial headlines without the weight of a Didot or Bodoni. Its moderate contrast and generous letterforms read clearly at 4rem while its italic cuts add personality to pull quotes and stat numbers. DM Sans handles everything else — body text, navigation, labels, captions. Its geometric construction and high x-height make it exceptionally legible at small sizes on screen. The serif–sans pairing is the defining editorial gesture: it signals "long-form, considered content" to the reader before they read a single word.
Primary Typefaces
Type Scale
Responsive type scale: H1–H6, Body, Label. Use these for consistent hierarchy.
Iconography
Icons use a 24px stroke-based style at 2px weight. Stroke icons were chosen over filled ones because they feel lighter — they complement the editorial aesthetic without competing with the serif headlines or creating visual heaviness. The 24px default pairs with body text; 16px is available for inline use alongside labels and captions.
Usage: prefer 24px for UI; 16px for inline; always pair with a label or tooltip for accessibility.
Grid & Layout
Column counts, gutter widths, and responsive breakpoints.
- Columns: 12-column grid on desktop; 8 on tablet; 4 on mobile.
- Gutter: 24px (var(--space-6)) between columns.
- Max container width: 1200px for article content.
- Breakpoints: 768px (mobile), 992px (tablet), 1100px (desktop), 1200px (wide).
Spacing Scale
8px base increment for margins and padding. Use tokens for consistency.
Elevation & Shadows
Z-index layers and shadow styles for depth.
- z-index: dropdown 100, sticky 200, modal 300, toast 400, tooltip 500.
- Shadows: xs → sm → md → lg → xl for cards, modals, and overlays.
Labels: xs, sm, md, lg, xl
2. Component Library (The "Molecules")
Components inherit the editorial aesthetic: 4px border-radius softens without making things feel childish, black primary buttons convey seriousness, and the serif headline font appears in stat numbers and card titles to maintain the magazine feel even inside interactive elements. Every component uses design tokens so a single CSS variable override can re-theme the entire system for a different project.
Buttons
Primary buttons are ink-black because the editorial system's personality comes from typography, not color. A black primary button says "this is the action" without fighting the per-project accent color. Danger buttons (semantic red) are the only exception — they break the monochrome deliberately to signal irreversible actions.
Form Elements
Inputs use the system sans at 1rem with generous padding for comfortable data entry. The focus state uses a subtle box-shadow (3px, black at 10% opacity) rather than a bright accent ring — this keeps the editorial calm intact while clearly marking the active field for keyboard users.
Navigation
The sticky sidebar mirrors the table of contents in a physical magazine. It uses the sans typeface at small size with generous letter-spacing — the same treatment as magazine section labels. On mobile, it collapses to a horizontal top bar, preserving the full viewport width for content.
Feedback & Overlays
Modals use the serif font for their title and a generous 8px border-radius to feel like a polished overlay, not a system dialog. Toasts are ink-colored by default and use semantic colors (green, amber, red) only when the message type is meaningful. The 40% backdrop opacity maintains reading context while clearly signaling a modal state.
Modal title
Body copy for the dialog. Keep it concise.
60%
Data Display
Tables use a borderless top with a subtle bottom-border per row — the same visual language as a magazine index. Badges are small, rounded labels using semantic backgrounds to indicate status. The tooltip component was designed for editorial UIs where space is tight and context is needed without cluttering the layout.
| Name | Role | Status |
|---|---|---|
| Alice | Designer | Active |
| Bob | Developer | Pending |
Selection
Sliders and segmented controls.
Legacy Components
These components are specific to case study pages. The stat grid uses italic serif numbers because research metrics deserve the visual weight and personality of a headline font — readers scan numbers before text, and the serif italic makes them unmissable. The 1px-gap card grid uses a clever CSS technique: the parent element's background color becomes the border, eliminating the need for individual border properties.
Stat Grid
Used in hero sections to highlight key metrics. 1px gap creates the grid effect.
Card Grid
Problem statements, findings, and features. Dark 1px borders create visual separation.
First Problem
Description of the problem or finding. Keep it concise and scannable.
Second Problem
Description of the problem or finding. Keep it concise and scannable.
Third Problem
Description of the problem or finding. Keep it concise and scannable.
Inline Quote
Pull quotes and testimonials with accent-colored left border.
Dark Results Section
High-contrast section for highlighting key outcomes and impact metrics.
Key Outcomes
This dark section creates visual contrast and signals important results or conclusions. It breaks the reading rhythm intentionally.
Layout Structure
Page Anatomy
Every case study follows this structural pattern:
(sticky)
Lede → Sections → Components → Skills → Footer
Spacing System
Consistent spacing creates rhythm and hierarchy:
- Section gap: 4rem between major sections
- Component gap: 3rem between components within sections
- Paragraph gap: 1.25rem between paragraphs
- Grid gap: 1px for card/stat grids (creates border effect)
- Article padding: 4rem horizontal on desktop
Max Widths
- Article container: 1200px
- Body text: 680px (optimal line length)
- Lede paragraph: 800px
3. Pattern Library (The "Organisms")
Patterns assemble atoms and molecules into product-level compositions. Each pattern encodes a design opinion: search bars are always inline with filters (not hidden behind a toggle), empty states use a large icon and a single CTA (invitation over frustration), and authentication cards are centered with generous shadow to feel trustworthy. These patterns were designed to look native to the editorial system while solving universal UX problems.

Responsive Behavior
The design adapts at three breakpoints:
- 1100px: Hero becomes single column, grids stack
- 992px: Navigation moves to top, horizontal layout
- 768px: Reduced type scale, simplified spacing
Navigation transforms from a sticky sidebar to a horizontal top bar on tablet and mobile, preserving space for content.
4. Governance & Documentation (The "Rules")
An editorial design system is only as good as its consistency. These rules exist because the serif–sans pairing, the warm paper tone, and the restrained color palette can be undermined by a single off-brand component. Governance isn't bureaucracy — it's the discipline that makes the system feel like a coherent publication rather than a collection of parts.
Accessibility (A11y)
- WCAG: Target Level AA. Ensure sufficient contrast (4.5:1 for body text, 3:1 for large text).
- ARIA: Use
aria-labelon icon-only buttons,aria-livefor dynamic content,role="dialog"for modals. - Keyboard: All interactive elements focusable; support Tab order; Escape closes modals; Enter/Space activate buttons.
- Focus: Visible focus ring (e.g. 2px outline or box-shadow). Don’t remove focus styles without a replacement.
Content Strategy
- Voice & tone: Clear, professional, and concise. Avoid jargon in UI copy.
- Grammar: Use sentence case for headings and buttons; title case only when appropriate (e.g. product names).
- Labels: Use actionable button labels ("Save changes" not "Submit"). Error messages should explain what went wrong and how to fix it.
Developer Handover
How to install and use the library in code.
- Install: No NPM package yet; copy
design-system.htmlstyles or extract CSS variables and component classes into your project. - Code snippets: Use the same class names (e.g.
.btn .btn-primary,.form-input) for consistency. React/Vue components can wrap these classes. - CSS: All tokens are in
:root. Override--color-brand-primary,--paper, etc. for theming.
Contribution Model
- Suggest: Propose new components or tokens via issue or doc update; include use case and mockup if possible.
- Test: New components must work across breakpoints and meet contrast/keyboard requirements.
- Add: Update this design system page and the shared CSS/component library; document usage and props.
Asset Library

- Sync design tokens (colors, spacing, type) with this page so design and code stay aligned.
Implementation Notes
CSS Custom Properties
All colors and font stacks are defined as CSS variables in :root, making theme changes
trivial—just update the accent color per project.
Grid Technique
Card grids use a clever technique: the parent has the border color as background, with 1px gap, and children have the paper color. This creates borders without actual border properties.
Drop Cap
The lede paragraph uses ::first-letter pseudo-element for the drop cap effect, floated left
with careful line-height tuning.
App Examples
A design system's true test is whether it adapts across platforms. The editorial aesthetic — serif headlines, warm paper, and restrained color — must work on a streaming TV interface, a smartwatch notification, and a mobile blog feed. These examples demonstrate that the same design tokens produce interfaces that feel cohesive regardless of screen size.
