# Material UI styling
Agent skill for picking the correct styling layer in Material UI (narrowest scope first). SKILL.md is the entry and index; AGENTS.md is the full guide.
## When to apply
- Choosing among `sx`, `styled()`, theme `components`, or global CSS for a change
- Overriding component slots or state safely
- Comparing `sx` vs `styled()` semantics (spacing, theme shortcuts)
## Sections in AGENTS.md (by priority)
| Order | Topic | Scope |
| :---- | :----------------------------- | :------------------------------------ |
| 1 | Quick decision | Pick `sx` → `styled` → theme → global |
| 2 | `sx` prop | One-off / local |
| 3 | `styled()` | Reusable wrapper |
| 4 | `createTheme({ components })` | All instances |
| 5 | `GlobalStyles` / `CssBaseline` | HTML baseline / globals |
| 6 | `sx` vs `styled()` table | Foot-gun prevention |
