Railway UI Skills

Railway UI 设计指南

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

为AI Agent构建Railway风格界面的专属约束规范。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景中参考本指南：

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

Colors

色彩规范

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 7
MUST use
```
#0F0E14
```
as page background (
```
surface-base
```
)
MUST use
```
#0B1025
```
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）——检测到的亮度为7
必须使用
```
#0F0E14
```
作为页面背景（
```
surface-base
```
）
必须使用
```
#0B1025
```
作为主要操作和聚焦状态的颜色（
```
accent
```
）
应精简调色板（当前检测到19种颜色）
为保证可访问性，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, 3px, 4px, 5px, 8px, 12px, 14px
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栅格来设置间距
应使用以下间距刻度：1px, 2px, 3px, 4px, 5px, 8px, 12px, 14px
元素间默认间距应使用2px
绝不能使用任意间距值（必须使用设计刻度）
容器内的内边距应保持一致

SHOULD use consistent element widths: 81px, 8px, 72px, 62px, 708px
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
应使用一致的元素宽度：81px, 8px, 72px, 62px, 708px

绝不能使用
```
h-screen
```
，应使用
```
h-dvh
```
来设置全屏高度
固定元素必须遵循
```
safe-area-inset
```

Animation

性能规范

NEVER add animation unless it is explicitly requested
MUST animate only compositor props (
```
transform
```
,
```

```
)
NEVER animate layout properties (
```
width
```
,
```

```
,
```
top
```
,
```
left
```
,
```
margin
```
,
```
padding
```
)
SHOULD use
```
ease-out
```
on entrance animations
NEVER exceed
```
200ms
```
for interaction feedback
SHOULD respect
```
prefers-reduced-motion
```

绝不能对大面积
```
blur()
```
或
```
backdrop-filter
```
（背景滤镜）区域执行动画
绝不能在非活跃动画外使用
```
will-change
```
（预渲染）
任何可通过渲染逻辑实现的功能，绝不能使用
```
useEffect
```

Performance

—

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
