Appearance Pattern

<SignIn
  appearance={{
    variables: {
      colorPrimary: '#0000ff',
      borderRadius: '0.5rem',
    },
    layout: {
      logoImageUrl: '/logo.png',
      socialButtonsVariant: 'iconButton',
    },
  }}
/>

variables (colors, typography, borders)

| Property | Description | |----------|-------------| | colorPrimary | Primary color throughout | | colorBackground | Background color | | borderRadius | Border radius (default: 0.375rem) |

layout (structure, logo, social buttons)

| Property | Description | |----------|-------------| | logoImageUrl | URL to custom logo | | socialButtonsVariant | 'blockButton' | 'iconButton' | 'auto' | | socialButtonsPlacement | 'top' | 'bottom' |

shadcn Theme

If the project has components.json (shadcn/ui installed), use the shadcn theme:

import { shadcn } from '@clerk/themes'

<ClerkProvider
  appearance={{
    theme: shadcn,
  }}
/>

Also import shadcn CSS in your global.css:

@import 'tailwindcss';
@import '@clerk/themes/shadcn.css';

Workflow

1. Identify customization needs (colors, layout, theme, CSS)
2. WebFetch the appropriate documentation from table above
3. Follow official code examples from the docs
4. Apply appearance prop to your Clerk components

Common Pitfalls

| Issue | Solution | |-------|----------| | Colors not applying | Use colorPrimary not primaryColor | | Logo not showing | Put logoImageUrl inside layout: {} | | Social buttons wrong | Add socialButtonsVariant: 'iconButton' in layout | | Styling not working | Use appearance prop, not direct CSS (unless with bring-your-own-css) |
