Gumroad UI Skills

Gumroad UI 设计规范

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

为借助AI Agent构建Gumroad风格界面提供的约束性设计准则。

When to Apply

适用场景

Reference these guidelines when:

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

在以下场景中参考本指南：

构建暗色模式界面
创建Gumroad风格的设计系统
实现基于Inter字体和4px网格的UI

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
```
)
SHOULD reduce color palette (currently 16 colors detected)
MUST maintain text contrast ratio of at least 4.5:1 for accessibility

主要界面必须使用深色背景（亮度<20）——检测到的亮度为0
必须使用
```
#000000
```
作为页面背景色（
```
surface-base
```
）
建议精简调色板（当前检测到16种颜色）
为保障可访问性，文本对比度必须至少达到4.5:1

Spacing

间距规范

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

必须使用4px网格进行间距布局
建议使用以下间距值：1px, 2px, 5px, 6px
元素间默认间距建议使用6px
绝不能使用任意间距值（需遵循设计规范）
容器内边距应保持一致

Borders

边框规范

MUST use border-radius from scale: 16px, 19px, 21px, 22px, 23px
SHOULD use 21px+ radius for pill-shaped elements
SHOULD limit border widths to: 1px, 2px
SHOULD use 19px as default border-radius
NEVER use arbitrary border-radius values (use design scale)
SHOULD use subtle borders (1px) for element separation

必须使用以下圆角值：16px, 19px, 21px, 22px, 23px
胶囊状元素建议使用21px及以上的圆角
边框宽度建议限制为：1px, 2px
默认圆角建议使用19px
绝不能使用任意圆角值（需遵循设计规范）
元素分隔建议使用细微边框（1px）

Border Radius Reference

圆角参考

Scale: 16px, 19px, 21px, 22px, 23px

规范值： 16px, 19px, 21px, 22px, 23px

Layout

布局规范

MUST design for 1920px base viewport width
SHOULD use consistent element widths: 16px, 730px, 246px, 31px, 196px
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
建议使用统一的元素宽度：16px, 730px, 246px, 31px, 196px
建议采用文本为主的布局，层级清晰
绝不能使用
```
h-screen
```
，应使用
```
h-dvh
```
实现全屏高度
固定元素必须遵循
```
safe-area-inset
```
安全区域规则
方形元素建议使用
```
size-*
```
而非
```
w-*
```
+
```
h-*
```
