Webflow UI Skills

Webflow UI 设计指南

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

用于借助AI Agent构建Webflow风格界面的约束规范。

When to Apply

适用场景

Reference these guidelines when:

Building dark-mode interfaces
Creating Webflow-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
创建受Webflow启发的设计系统
实现采用Inter字体与4px网格的UI

Colors

颜色规范

MUST use dark backgrounds (lightness < 20) for primary surfaces - detected lightness: 8
MUST use
```
#151515
```
as page background (
```
surface-base
```
)
MUST use
```
#8DB8F2
```
for primary actions and focus states (
```
accent
```
)
SHOULD reduce color palette (currently 33 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）——当前检测亮度：8
页面背景必须使用
```
#151515
```
（
```
surface-base
```
）
主要操作与焦点状态必须使用
```
#8DB8F2
```
（
```
accent
```
）
应精简调色板（当前检测到33种颜色）
为保障可访问性，文本对比度必须至少达到4.5:1

SHOULD maintain consistent padding within containers

必须使用4px网格进行间距布局
应使用以下间距刻度：1px, 2px, 3px, 4px, 5px, 7px, 9px, 13px
元素间默认间距应使用3px
不得使用任意间距值（需遵循设计刻度）
容器内边距应保持一致

SHOULD limit border widths to: 1px, 2px
SHOULD use 2px as default border-radius
NEVER use arbitrary border-radius values (use design scale)

```
safe-area-inset
```
for fixed elements
SHOULD use
```
size-*
```
for square elements instead of
```
w-*

不得使用
```
h-screen
```
，需使用
