Customise appearance

const appearance = {
  theme: 'stripe',
};
stripe.initCheckout({
  fetchClientSecret,
  elementsOptions: {
    appearance,
  },
});

1. Start by picking a theme.

Get up and running right away by choosing the pre-built theme that most closely resembles your website.

1. Customise the theme using variables .

Set variables such as fontFamily and colorPrimary to broadly customise components appearing throughout each Element.

1. If needed, fine-tune individual components and states using rules .

For complete control, specify custom CSS properties for individual components appearing in the Element.

Themes

Start customising Elements by picking from one of the following themes:

• stripe
• night
• flat

const appearance = {
  theme: 'night'
};

Variables

Set variables to affect the appearance of many components appearing throughout each Element.

The variables option works like CSS variables. You can specify CSS values for each variable and reference other variables with the var(--myVariable) syntax. You can even inspect the resulting DOM using the DOM explorer in your browser.

const appearance = {
  theme: 'stripe',

  variables: {
    colorPrimary: '#0570de',
    colorBackground: '#ffffff',
    colorText: '#30313d',
    colorDanger: '#df1b41',
    fontFamily: 'Ideal Sans, system-ui, sans-serif',
    spacingUnit: '2px',
    borderRadius: '4px',
    // See all possible variables below
  }
};

Commonly used variables

Rules

The rules option is a map of CSS-like selectors to CSS properties, allowing granular customisation of individual components. After defining your theme and variables, use rules to seamlessly integrate Elements to match the design of your site.

const appearance = {
    rules: {
      '.Tab': {
        border: '1px solid #E0E6EB',
        boxShadow: '0px 1px 1px rgba(0, 0, 0, 0.03), 0px 3px 6px rgba(18, 42, 66, 0.02)',
      },

      '.Tab:hover': {
        color: 'var(--colorText)',
      },

      '.Tab--selected': {
        borderColor: '#E0E6EB',
        boxShadow: '0px 1px 1px rgba(0, 0, 0, 0.03), 0px 3px 6px rgba(18, 42, 66, 0.02), 0 0 0 2px var(--colorPrimary)',
      },

      '.Input--invalid': {
        boxShadow: '0 1px 1px 0 rgba(0, 0, 0, 0.07), 0 0 0 2px var(--colorDanger)',
      },

      // See all supported class names and selector syntax below
    }
  };

All rules

The selector for a rule can target any of the public class names in the Element, as well as the supported states, pseudo-classes, and pseudo-elements for each class. For example, the following are valid selectors:

• .Tab, .Label, .Input
• .Tab:focus
• .Input--invalid, .Label--invalid
• .Input::placeholder

The following are not valid selectors:

• .p-SomePrivateClass, img, only public class names can be targeted
• .Tab .TabLabel, ancestor-descendant relationships in selectors are unsupported
• .Tab--invalid, the .Tab class does not support the --invalid state

Each class name used in a selector supports an allowlist of CSS properties, that you specify using camel case (for example, boxShadow for the box-shadow property).

The following is the complete list of supported class names and corresponding states, pseudo-classes, and pseudo-elements.

Make sure that you choose a font size of at least 16px for input fields on mobile.

Picker

Make sure your .PickerItem active state stands out amongst the other states.

DO Use a noticeable, high-contrast primary colour, weight, and/or outline to distinguish the active state your customer has already selected.	DON’T Don’t use two equally weighted options or low-contrast colours for your .PickerItem states because it makes distinguishing which one is active more difficult.

Menu

Accordion

Payment Method Messaging Element

Radio Icon

You can control the overall size of the icon with the width property on .RadioIcon. You can control the relative size of .RadioIconInner with the r (radius) property. .RadioIconOuter and .RadioIconInner are SVG elements and can be styled with stroke and fill properties. See the full list of supported CSS properties below.

const appearance = {
  rules: {
    '.RadioIcon': {
      width: '24px'
    },
    '.RadioIconOuter': {
      stroke: '#E0E6EB'
    },
    '.RadioIconInner': {
      r: '16'
    }
  }
};

Other configuration options

In addition to themes, variables and rules, we have provided additional appearance configuration options to style Elements.

You can customise these by adding them to the appearance object:

const appearance = {
  labels: 'floating',

  // other configurations such as `theme`, `variables` and `rules`...
}

We currently support the following options:
