• Usage: Educational highlights, training materials

2. Spacing System (8px Grid) - MANDATORY

Always use multiples of 8 for ALL spacing:

• 8px - Tight spacing (icon-to-label, tight groups)
• 16px - Default spacing between related elements, form field spacing
• 24px - Spacing between component groups, card padding (minimum)
• 32px - Section padding, comfortable card padding
• 48px - Large section gaps, major spacing
• 64px - Major layout divisions, page sections

Rules:

• NEVER use arbitrary spacing values (no 15px, 20px, 37px, etc.)
• Always round to nearest 8px multiple
• Consistent spacing creates visual rhythm
• Exception: 4px allowed for very tight micro-spacing (but prefer 8px)

3. Typography

Font Families

• Digital/Screen: Arial (fallback) or Rotis Sans Serif (if licensed)
• Maximum 2 font families per interface
• System font stack: Arial, -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto

Typography Hierarchy

Headings:

• H1: 32-40px (page titles) - MLP Blau Dark (#033D5D)
• H2: 24-28px (section headers) - MLP Blau Dark (#033D5D)
• H3: 20-24px (subsections) - Text Dark (#2B2B2B)
• Body: 16px minimum (NEVER smaller for readability)
• Small text: 14px (metadata, captions, fine print)

Text Rules:

• Line height: 1.5-1.6 for body text
• Maintain clear visual hierarchy through size AND color
• MLP Blau Dark for main headings (mandatory)
• Text Dark for body content
• Text Medium for secondary information

Accessibility Requirements (Barrierefreiheit)

WCAG Compliance - MANDATORY:

• Text under 18px: minimum 4.5:1 contrast ratio to background
• Larger elements (18px+): minimum 3:1 contrast ratio
• CRITICAL: Never communicate information through color alone
  • ✓ Error: Red color + "Fehler:" text + X icon
  • ✗ Error: Just red color
• All interactive elements need visible focus states for keyboard navigation

4. Shadows and Depth

Subtle Shadows (Preferred):

box-shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24);

Rules:

• Use subtle shadows, avoid dramatic effects
• Prefer borders (Titanium #BEB6AA) over shadows when appropriate
• Reserve stronger shadows for modals and elevated elements
• NEVER combine heavy shadow AND border on same element

5. Border Radius

Standard Radii:

• 4px - Subtle (inputs, small buttons)
• 8px - Moderate (cards, larger buttons)
• 12px - Pronounced (featured elements)

Rules:

• Not everything needs to be rounded
• Use consistently within each component type
• Sharp corners (0px) acceptable for cards and containers
• Fully rounded only for avatars, pills, badges

6. Interactive States - MANDATORY

Every interactive element MUST have clear states:

Buttons:

• Default: Base styling with subtle shadow
• Hover: Background darkens 10-15%, slight shadow increase
• Active: Background darkens 20%, shadow reduces
• Disabled: Opacity 0.5-0.6, cursor: not-allowed, no hover effect
• Focus: Visible outline (2px solid, offset 2px)

Links:

• Default: Underline or clear color differentiation
• Hover: Color shift or underline appears
• Visited: Optional subtle color change
• Focus: Visible outline

Form Inputs:

• Default: Border with subtle color
• Hover: Border color intensifies
• Focus: Border color change + outline
• Error: Red border + error message below
• Disabled: Gray background, cursor: not-allowed

Mobile-First Approach

Mobile Rules:

• Touch targets: Minimum 44x44px
• Padding: Minimum 24px on mobile
• Font sizes: 16px minimum (prevents zoom on iOS)
• Spacing: Use 8px grid but may tighten on very small screens

10. Special Notes for Trainers/Dozenten

As a trainer creating materials for different audiences:

General Financial Planning:

• Use standard MLP palette
