Front UI Skills

Front UI 设计规范

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

用于借助AI Agent构建Front风格界面的约束规范。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景中参考本指南：

构建浅色模式界面
创建受Front启发的设计系统
实现采用Inter字体和4px网格的UI

Colors

颜色规范

SHOULD use light backgrounds for primary surfaces
MUST use
```
#FFFFFF
```
as page background (
```
surface-base
```
)
MUST use
```
#C8CC51
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 30 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主界面区域应使用浅色背景
必须使用
```
#FFFFFF
```
作为页面背景（
```
surface-base
```
）
主要操作和焦点状态必须使用
```
#C8CC51
```
（
```
accent
```
）
应精简调色板（当前检测到30种颜色）
为保障可访问性，必须保持文本对比度至少为4.5:1
