Design Process

Follow this workflow for creating HTML designs:

1. Discovery & Planning

  • Understand the purpose and goals
  • Identify target audience
  • Review content and requirements
  • Establish design direction

2. Visual Design

  • Choose appropriate color palette (2-3 colors for balance)
  • Select typography system (2-3 fonts maximum)
  • Establish visual hierarchy with size, weight, color
  • Plan grid system and alignment
  • Design with white space intentionally

3. HTML Structure

  • Use semantic HTML5 elements (<header>, <nav>, <main>, <article>, <section>, <footer>)
  • Implement proper heading hierarchy (h1-h6)
  • Add accessibility attributes (ARIA labels, alt text)
  • Include skip navigation links
  • Structure for responsive behavior

4. Class Naming

  • Use descriptive, meaningful class names
  • Follow BEM or similar methodology for consistency
  • Add modifier classes for variations
  • Prepare for CSS implementation

5. Accessibility

  • Add descriptive alt text for images
  • Include ARIA labels for navigation
  • Ensure semantic structure
  • Test keyboard navigation path
  • Check color contrast ratios

6. Responsive Considerations

  • Mobile-first approach
  • Flexible images (width="x" height="y" with max-width CSS)
  • Viewport meta tag
  • Touch-friendly sizing (44x44px minimum)
  • Readable text sizes (16px minimum for body)

Typography Best Practices

When implementing typography:

  • Limit type sizes: 3 sizes establish clear hierarchy (large for emphasis, medium for importance, small for details)
  • Line length: 45-75 characters for optimal readability
  • Line height: 1.5× font size as starting point, adjust for typeface
  • Font pairing: Contrast personalities (display + neutral) with similar proportions
  • Hierarchy through contrast: Use size, weight, and spacing to signal importance

Color Usage Guidelines

When working with color:

  • Start with monochromatic: Single hue with variations is safest, most sophisticated
  • Limit palette: 2-3 colors maximum for balance and hierarchy
  • Reserve bright colors: Use for calls-to-action and emphasis only
  • Check accessibility: Ensure WCAG contrast ratios (4.5:1 for body text, 3:1 for large text)
  • Consider psychology: Choose colors that align with brand message and audience expectations

Grid and Layout Principles

When structuring layouts:

  • Use grids consistently: 12-column or 4-column systems provide flexibility
  • Align to grid: All elements should snap to column edges or centers
  • Vary column spans: Mix full-width, half-width, third-width for visual interest
  • Consistent gutters: Maintain uniform spacing between columns
  • Adapt for mobile: Collapse multi-column layouts to single columns on small screens

Accessibility Checklist

Every HTML design must include:

  • ✓ Semantic HTML elements for structure
  • ✓ Proper heading hierarchy (only one h1, logical h2-h6 progression)
  • ✓ Alt text for meaningful images (empty alt for decorative images)
  • ✓ ARIA labels for navigation and interactive elements
  • ✓ Skip navigation link for keyboard users
  • ✓ Sufficient color contrast
  • ✓ Keyboard-accessible interactive elements
  • ✓ Viewport meta tag for responsive behavior
  • ✓ Lang attribute on html element
  • ✓ Descriptive link text (avoid "click here")

Common Patterns to Implement

Familiarize yourself with these common web design patterns:

Hero Sections: Large, prominent area at page top with headline, description, and call-to-action

Card Layouts: Contained content blocks with image, heading, description, and link

Grid Galleries: Multi-column layouts showcasing visual content

Feature Lists: Services or benefits presented in multi-column format with icons

Testimonials: Customer quotes with attribution, often in cards or blockquotes

Call-to-Action Sections: Focused areas prompting specific user actions

Footer Navigation: Multi-column footer with links, contact info, and branding

Quality Standards

Before considering a design complete, ensure:

  1. Visual Hierarchy: Can users instantly identify the most important elements?
  2. Readability: Is all text comfortably readable at intended sizes?
  3. Balance: Does the design feel stable and well-distributed?
  4. Consistency: Are spacing, colors, and typography used consistently?
  5. Accessibility: Does the design meet WCAG 2.1 AA standards?
  6. Responsiveness: Does the layout work on mobile, tablet, and desktop?
  7. Performance: Are images optimized and loading attributes used?

Examples and Inspiration

When seeking inspiration:

  • Study the reference files for principle applications
  • Review asset templates for pattern implementations
  • Analyze award-winning websites (Awwwards, CSS Design Awards)
  • Examine minimalist designs for white space usage
  • Look at editorial layouts for typography excellence
  • Study luxury brands for sophisticated color usage

Troubleshooting Common Issues

Hierarchy unclear: Increase size contrast between levels, use weight variations

Feels cluttered: Add more white space, remove unnecessary elements, group related items

Colors clash: Simplify palette, use monochromatic scheme, check color harmonies

Not accessible: Check contrast ratios, add semantic HTML, include ARIA labels

Doesn't scale: Use relative units, test at multiple sizes, embrace fluid layouts

Too generic: Add personality through typography, strategic color use, or unique layouts

Collaboration with Designers

When working with design briefs or mockups:

  • Ask about grid system and alignment intentions
  • Clarify typography choices (fonts, sizes, weights)
  • Understand color palette rationale
  • Discuss responsive behavior expectations
  • Confirm accessibility requirements
  • Request asset optimization guidance
