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:

Visual Hierarchy: Can users instantly identify the most important elements?
Readability: Is all text comfortably readable at intended sizes?
Balance: Does the design feel stable and well-distributed?
Consistency: Are spacing, colors, and typography used consistently?
Accessibility: Does the design meet WCAG 2.1 AA standards?
Responsiveness: Does the layout work on mobile, tablet, and desktop?
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
