Interface Design
Design Principles
1. Clarity
Make the interface obvious. Users shouldn't have to guess.
2. Consistency
Same actions, same results. Maintain patterns throughout.
3. Feedback
Respond to every action. Show progress, confirm success, explain errors.
4. Efficiency
Minimize steps. Optimize common workflows.
5. Forgiveness
Allow undo. Confirm destructive actions. Recover gracefully.
UI Patterns
Navigation
- Top Nav: Primary navigation, global actions
- Side Nav: Section navigation, hierarchical content
- Breadcrumbs: Show location in hierarchy
- Tabs: Switch between related views
Forms
- Label above input
- Clear validation messages
- Inline validation where helpful
- Logical field grouping
- Clear call-to-action
Feedback
- Loading states
- Success confirmations
- Error messages
- Empty states
- Progress indicators
Actions
- Primary action prominent
- Secondary actions subtle
- Destructive actions require confirmation
- Disabled states clear
Layout Principles
Visual Hierarchy
- Size indicates importance
- Color draws attention
- Spacing groups elements
- Alignment creates order
Grid System
.container {
display: grid;
grid-template-columns: repeat(12, 1fr);
gap: 1rem;
}
