AI-Created Design System: A Mobile-First Approach
From responsive components to automated accessibility checks — Design partner Yuna shares her AI-driven design system experience.
Why Mobile First?
A significant share of Korean web traffic comes from mobile (per KISA Internet Usage Survey). Yet many services still design for desktop first and "adapt" to mobile. This creates critical UX flaws on mobile.
Yuna's Design Principles
1. Minimum 48px Touch Target
We set minimum touch areas of 48×48px for buttons, links, and interactive elements on mobile. Anything smaller dramatically increases mis-tap rates.
2. Content Hierarchy First
On mobile screens, only one key piece of information should show at a time. Desktop sidebar info converts to accordions or tabs.
3. Dark Mode Default
Dark mode is the default to improve battery efficiency on OLED devices and reduce eye strain for nighttime users.
4. word-break: keep-all
When Korean text breaks mid-word, readability drops significantly. We apply word-break: keep-all to all text blocks.
What AI Checks Automatically
- Color contrast ratio (WCAG AA standard: 4.5:1 or higher)
- Touch target size verification
- Minimum 13px font size check
- Image alt text presence
- Keyboard navigation support
