Flat Design
Flat design uses simple shapes, solid colors, and clear flat areas, with little fake depth.
Another example
A public transit app uses clear icons, solid colors, and bold type instead of shine.
Main parts
- 01Content surface
- 02Distinct visual treatment
- 03Action and readability check
Use it when
Use it when speed, easy reading, and calm visuals matter more than real-looking materials.
Do not use it when
Never remove all signs that something can be used. Flat controls still need clear states and edges.
Name used in code
solid planes + minimal depth Before you ship
Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience.
Outcome: Use or define Flat Design to make the visual experience clear and easy to use. User context: A public transit app uses clear icons, solid colors, and bold type instead of shine. Design concept to apply: Flat Design. Why it fits: Use it when speed, easy reading, and calm visuals matter more than real-looking materials. Do not use it when: Never remove all signs that something can be used. Flat controls still need clear states and edges. Design requirements: Set the content order, shared design values, and reusable components. Define how the layout changes by screen size and state. Keep useful design choices separate from decoration. Inclusion and resilience: Check contrast, zoom, languages, themes, and reduced motion when needed. Do not use color or effects as the only way to show meaning. Acceptance criteria: The design stays clear on phones and desktops, at zoom, in every theme, and in all supported languages. Interactive states stay clear and consistent. Evidence and limits (evidence boundary): No single official standard controls the whole term. Its meaning may change across teams, platforms, or frameworks. Unknowns to confirm: Brand limits, amount of content, supported themes and languages, target devices, and design-system rules.

Release checks: Check content order, shared design values, component consistency, contrast, zoom, and layout changes by screen size. Verify every theme, language, and state. If there is motion, offer an equal reduced-motion experience. Before changing code, report the evidence you found, gaps, severity, and the smallest safe fix.
