Visual foundations
Build a hierarchy that makes the screen easy to understand at a glance.
Lesson
A clear interface guides attention. Size, weight, contrast, position, and spacing tell people what matters first. Start with the content and task; decorative color comes later.
Key ideas
- Hierarchy and grouping
- Type scale
- Contrast and semantic color
- Consistent spacing
Practice challenge
Turn the starter content into a welcome card with three levels: title, description, and action. Make the title stand out and the button easy to find.
- The title is at least 24 px.
- The description is smaller than the title.
- There is clear spacing between content and action.
