Material UI v9 Patterns

Purpose

Target Material UI 9.2.x, the current stable major as of 2026-08-03. Inspect the consuming project's package.json before changing code; preserve its installed major unless the user requests an upgrade.

For detailed examples, read only the relevant resource:

• resources/component-library.md: component and layout examples
• resources/styling-guide.md: sx, styled, slots, and CSS layers
• resources/theme-customization.md: themes, CSS variables, and color schemes

Version and installation

Use compatible major versions for Material UI packages:

npm install @mui/material@^9.2.0 @mui/icons-material@^9.2.0 @emotion/react @emotion/styled
