Matter UI Skills

Matter UI 设计指南

Opinionated constraints for building Matter-style interfaces with AI agents.

用于借助AI Agent构建Matter风格界面的约束性指南。

When to Apply

适用场景

Reference these guidelines when:

Building dark-mode interfaces
Creating Matter-inspired design systems
Implementing UIs with Inter font and 4px grid

参考以下指南的场景：

构建深色模式界面时
创建受Matter启发的设计系统时
实现采用Inter字体和4px网格的UI时

Colors

色彩规范

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 0
MUST use
```
#000000
```
as page background (
```
surface-base
```
)
MUST use
```
#5560EC
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 19 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主界面必须使用深色背景（亮度<20）——检测到的亮度：0
页面背景（
```
surface-base
```
）必须使用
```
#000000
```
主要操作和焦点状态（
```
accent
```
）必须使用
```
#5560EC
```
应精简调色板（当前检测到19种颜色）
为保证无障碍性，文本对比度必须至少达到4.5:1

MUST use 4px grid for spacing
SHOULD use spacing from scale: 1px, 2px, 4px, 5px, 6px, 7px, 9px, 10px
SHOULD use 2px as default gap between elements
NEVER use arbitrary spacing values (use design scale)
SHOULD maintain consistent padding within containers

必须使用4px网格来设置间距
应使用以下间距刻度值：1px, 2px, 4px, 5px, 6px, 7px, 9px, 10px
元素之间的默认间距应设为2px
绝不能使用任意间距值（请使用设计刻度）
容器内的内边距应保持一致

MUST use border-radius from scale: 0px, 1px, 10px, 15px
SHOULD limit border widths to: 1px, 2px
SHOULD use 1px as default border-radius
NEVER use arbitrary border-radius values (use design scale)
SHOULD use subtle borders (1px) for element separation

必须使用以下圆角刻度值：0px, 1px, 10px, 15px
边框宽度应限制为：1px, 2px
默认圆角应设为1px
绝不能使用任意圆角值（请使用设计刻度）

Scale: 0px, 1px, 10px, 15px

刻度值： 0px, 1px, 10px, 15px

Layout

布局规范

MUST design for 1920px base viewport width
SHOULD use consistent element widths: 13px, 102px, 38px, 37px, 14px
SHOULD maintain text-heavy layout with clear hierarchy
NEVER use
```
h-screen
```
, use
```
h-dvh
```
for full viewport height
MUST respect
```
safe-area-inset
```
for fixed elements
SHOULD use
```
size-*
```
for square elements instead of
```
w-*
```
+
```
h-*
```

必须以1920px为基础视口宽度进行设计
应使用统一的元素宽度：13px, 102px, 38px, 37px, 14px
应保持文本为主的布局，并具备清晰的层级结构
绝不能使用
```
h-screen
```
，请使用
```
h-dvh
```
来设置全屏高度
固定元素必须遵循
```
safe-area-inset
```
规则
方形元素应使用
```
size-*
```
而非
```
w-*
```
+

SHOULD respect
```
prefers-reduced-motion
```

除非明确要求，否则绝不能添加动画
仅允许对合成器属性（

NEVER animate large
```
blur()
```
or
```
backdrop-filter
```
surfaces
NEVER apply
```
will-change

outside an active animation
NEVER use
```
useEffect
```
for anything that can be expressed as render logic

绝不能对大面积
```

```
或
```
backdrop-filter
```
区域执行动画
仅在动画活跃时使用
