Theming - Stytch Docs

The following applies to @stytch/vanilla-js v6, @stytch/react v20, or @stytch/nextjs v22. If you are on an older version, see documentation here.

To theme Stytch UI components, use the presentation property. You can use one of our pre-built themes, override specific tokens, or create an entirely new theme to match your app’s look and feel.

const presentation = {
  theme: { ... },
  options: { ... },
  icons: { ... },
};

Pre-built themes

You can use our default themes as a basis for your own theme.

Light theme

The light theme is the default and can be imported as defaultTheme.

shadcn theme

If you use shadcn/ui, you can use shadcnTheme to automatically match Stytch UI to your theme. Here are some examples of how Stytch UI appears with different shadcn/ui themes.

Default
Neobrutalism
Bubblegum
Amethyst dark

You will also need to add these lines to your CSS:

@import 'tailwindcss';
/* Or @stytch/nextjs, @stytch/vanilla-js */
@import '@stytch/react/theme/shadcn.css'; 

For dark mode to work, add these lines to your .dark class.

.dark {
  color-scheme: dark; 
  --st-dark-mode: 1; 
}

Customization

You can override any property in these theme objects. See the reference below for all available properties.

Automatic light/dark themes

You can also provide an array of two themes, and Stytch UI will automatically switch between them based on the user’s OS color scheme.

Creating your own theme

You can create your own theme using this template. The template contains the default value for each property. Feel free to delete any properties where you want to use the default.

const myTheme = {
  'color-scheme': 'light',

  // Fonts
  'font-family': 'system-ui, sans-serif',
  'font-family-mono':
    "ui-monospace, 'Cascadia Code', 'Source Code Pro', Menlo, Consolas, 'DejaVu Sans Mono', monospace",

  // Sizes
  spacing: '4px',
  'text-base': '1rem',
  'container-width': '400px',
  'mobile-breakpoint': '768px',
  'rounded-base': '4px',

  // Durations
  'transition-duration': '0.15s',

  // Shadows - no shadow is used by default
  shadow: '',

  // Colors
  background: 'oklch(1 0 0)',
  foreground: 'oklch(0.14 0 0)',

  primary: 'oklch(0.2 0 0)',
  'primary-foreground': 'oklch(0.99 0 0)',

  secondary: 'oklch(0.97 0 0)',
  'secondary-foreground': 'oklch(0.2 0 0)',

  muted: 'oklch(0.97 0 0)',
  'muted-foreground': 'oklch(0.56 0 0)',

  accent: 'oklch(0.97 0 0)',
  'accent-foreground': 'oklch(0.2 0 0)',

  border: 'oklch(0.92 0 0)',
  input: 'oklch(0.92 0 0)',
  ring: 'oklch(0.72 0 0)',

  destructive: 'oklch(0.577 0.245 27.325)',
  'destructive-foreground': '#fff',

  warning: 'oklch(0.67 0.16 58)',
  success: 'oklch(0.6 0.13 163)',
};

Additional properties

These properties are usually derived from base tokens but can be overridden if your theme needs different values.

const additionalThemeProperties = {
  // Defaults to font-family
  'header-font': '',

  // Container defaults to 6x base radius
  'container-radius': '',

  // Defaults to border
  'container-border': '',

  // Button and input defaults to 2x base radius
  'button-radius': '',
  'input-radius': '',

  // Default to shadow
  'shadow-button': '',
  'shadow-input': '',
};

CSS variables

You can also use CSS custom properties (a.k.a. CSS variables) as values. This is useful if you are using Tailwind or another framework that provides them.

const theme = {
  primary: 'var(--color-primary)',
};

TypeScript

Themes are typed as Theme. This object has every non-derived property marked as required. If you only intend to override a few properties from default, you can use Partial<Theme> instead.

Additional options

Logo and header customization

Use options.logo to configure the logo displayed at the top of the components. The logo will be resized to a maximum of 100×50px, but we recommend using an image at least 200×100px to support users with hi-dpi displays.

const presentation = {
  options: {
    url: 'https://example.com/logo.png',
    alt: 'Your company name',
  },
};

Use options.hideHeaderText to hide the heading and instruction text on some screens. This can be useful to avoid duplicating existing headings on the page and can be combined with setting theme['container-border'] to 0 to blend the components into the page.

const presentation = {
  options: {
    hideHeaderText: true,
  },
};

Without hideHeaderText

Icon customization

Icons can be customized by passing an object to presentation.icons where the keys are icon IDs and the value is a React component (not element) rendering the icon. A monochrome black and white logo set is available as an alternative to the default color one. Currently, we only allow customizing logos used in OAuth, SSO, email, or crypto products. These logos can be customized:

amazon
apple
bitbucket
coinbase
discord
facebook
figma
github
gitlab
google
linkedin
microsoft
salesforce
slack
snapchat
tiktok
twitch
xTwitter
yahoo
phantom
metamask
binance
gmail
outlook

You can also pass in a React component to replace the logo completely. The component should take a size prop and spread the rest of the props onto the root element.

const OutlookLogo = ({ size, ...props }) => (
  <svg width={size} height={size} {...props}>...</svg>
);

const presentation = {
  icons: {
    outlook: OutlookLogo,
  },
};

Shadow DOM style isolation

Use options.enableShadowDOM to use shadow DOM to isolate outer page styles. Use this option if you find Stytch UI’s styling are being overrode by the page’s stylesheet. In @stytch/react and @stytch/nextjs, this will also create an additional wrapper <div> to act as the shadow root for the component.

Compatibility

Our themes use the color-mix CSS function and the oklch color space to generate variant colors. If you need to support older browsers that do not support either of these, use addColorFallback() imported from /compat to generate the colors in JavaScript instead.

TypeScript

Types are available for all parts of presentation.

`presentation.options`

The presentation.options object customizes non-style-related aspects of the SDK’s appearance. You can specify some of them or none at all. We’ll use our defaults for the ones you don’t specify.
