Web Design Mastery

Production-grade UI design principles from Refactoring UI by Adam Wathan & Steve Schoger.

Core Design Workflow

1. Start with a Feature, Not a Layout

  • Design the actual piece of functionality first
  • Don't start with navigation, sidebar, or shell
  • Details come later—work in grayscale first
  • Don't design too much—work in cycles

2. Establish Systems Before Designing

Define these systems up front to eliminate decision fatigue:

Spacing Scale (px):

| Token | Size | Use Case | |-------|------|----------| | 1 | 4 | Micro gaps | | 2 | 8 | Tight, within components | | 3 | 12 | Related elements | | 4 | 16 | Section padding | | 6 | 24 | Between sections | | 8 | 32 | Major separation | | 12 | 48 | Large gaps | | 16 | 64 | Hero spacing | | 24 | 96 | Maximum separation |

Type Scale (px):

| Size | Use Case | |------|----------| | 12 | Labels, meta, fine print | | 14 | Body text, default | | 16 | Emphasis, subheadings | | 18 | Section headings | | 20 | Card titles | | 24 | Page section titles | | 30 | Page headings | | 36 | Hero subheading | | 48 | Hero heading | | 60-72 | Display text |

Shadow Scale (5 levels):

| Level | Use Case | |-------|----------| | 1 | Buttons, subtle lift | | 2 | Cards, inputs | | 3 | Dropdowns, popovers | | 4 | Sticky elements | | 5 | Modals, dialogs |

3. Build Hierarchy, Not Decoration

  • Primary: Dark color (headlines, key actions)
  • Secondary: Grey (supporting text, dates)
  • Tertiary: Light grey (metadata, copyright)

Key principles:

  • Size isn't everything—use weight and color
  • Emphasize by de-emphasizing competing elements
  • Labels are a last resort—combine with values
  • Semantics are secondary to hierarchy

4. Apply Depth Meaningfully

  • Light comes from above
  • Shadows convey elevation (closer = more attention)
  • Use two-part shadows for premium look
  • Consider overlapping elements for layers

5. Finish with Polish

  • Supercharge defaults (bullets → icons, style quotes)
  • Add accent borders for visual interest
  • Design empty states as first impressions
  • Use fewer borders—prefer shadows or spacing

Color System

Categories needed:

  1. Greys (8-10 shades): Text, backgrounds, panels, borders
  2. Primary (5-10 shades): Actions, active states, links
  3. Accents (per semantic): Success, warning, error states

Process for defining shades:

  1. Pick base color (500) that works as button background
  2. Pick edges (100 for tinted bg, 900 for text)
  3. Fill gaps: 700, 300 → 800, 600, 400, 200

Key rules:

  • Use HSL for intuitive adjustments
  • Increase saturation at lightness extremes
  • Rotate hue toward bright (60°, 180°, 300°) for lighter
  • Greys can be warm (yellow/orange tint) or cool (blue tint)
  • Accessibility: 4.5:1 contrast for normal text, 3:1 for large

Anti-Patterns

NEVER do:

  • Grey text on colored backgrounds (hand-pick colors instead)
  • Fill the whole screen when content needs less
  • Use grids religiously (fixed widths often better)
  • Ambiguous spacing (more space between groups than within)
  • Relative sizing that doesn't scale
  • Scale icons beyond intended size
  • Rely on color alone for meaning
