Styling the Inbox component

​

Customization Hierarchy

The Inbox component is built to allow for multiple layers of styling, which allows the specificity required to style the Inbox to meet the requirements of your use case.

Depending on the level of customization you need, you can choose to style the inbox using one of the following approaches:

• Appearance Prop
  • Variables - Global primitives such as buttons, popovers, dropdowns and etc…
  • Elements - Style individual elements
• Custom notification rendering - Render a custom notification item with complete control
• Custom Composition - Compose our components for custom layouts

​

Appearance Prop

The appearance prop can be used to customise the Inbox. It has three main keys: baseTheme, variables and elements.

• Variables: Global styling variables that apply to multiple elements within the inbox.
• Elements: Elements are the individual UI components that make up the Inbox.
• Base Theme: This is the default theme that comes with the inbox out of the box.

​

Variables

Variables are used to define global styling properties that can be reused throughout the inbox. You might want to use variables to the styling of multiple components at once, for example, if you want to change the border radius of all the components at once, you can do so by updating the colorPrimary variable, which will modify the CTA buttons, unseen counter and etc…

Appearance Variables

​

Styling Variables

You can override the default elements by passing your own styles or CSS classes to the elements object.

const appearance = {
  variables: {
    colorBackground: 'yellow',
  }
};

<Inbox appearance={appearance} />

​

Elements

The elements object allows you to define styles for these components. Each key corresponds to an component, and the value is an object containing style properties or you can also pass your css classes. Here’s a list of available elements that can be styled using the elements object in your appearance configuration:

​

Finding element selectors

You can inspect the elements you want to customize using the browser’s dev tools, each element has a unique selector that you can use to style starting with nv-.

Strip the nv- prefix when and add it to the elements object. For example, to style the nv-notificationPrimaryAction__button element, you can add the following to the elements object:

const appearance = {
  elements: {
    'notificationPrimaryAction__button': {
      backgroundColor: 'red',
    },
  },
}

Finding Element Selectors

​

Bring your own CSS

You can override the default elements by passing your own styles or CSS classes to the elements object.

​

Using Tailwind CSS

You can also use Tailwind CSS classes to style the Inbox components. You can pass the classes directly to the elements object.

import { Inbox } from "@novu/react";

const appearance = {
  elements: {
    bellIcon: "p-4 bg-white rounded-full",
    notification:
      "bg-white rounded-lg shadow-sm hover:shadow-md hover:bg-gray-50",
  },
};

export function Novu() {
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriberId="YOUR_SUBSCRIBER_ID"
      appearance={appearance}
    />
  );
}

​

Using CSS Modules

You can also use CSS Modules to style the Inbox components. Here’s how you can do it:

• Create a CSS module file (e.g. styles.module.css) with the styles you want to apply to the Inbox components.

.bellIcon {
  padding: 1rem;
  background-color: white;
  border-radius: 50%;
}

.bellIcon:hover {
  background-color: #f9fafb;
}

.notification {
  background-color: white;
  border-radius: 0.5rem;
  box-shadow: 0 1px 2px 0 rgba(0, 0, 0, 0.05);
}

.notification:hover {
  background-color: #f9fafb;
}

• Import the CSS module file and pass the classes to the elements object.

import { Inbox } from "@novu/react";
import styles from "./styles.module.css";

const appearance = {
  elements: {
    bellIcon: styles.bellIcon,
    notification: styles.notification,
  },
};

export function Novu() {
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriberId="YOUR_SUBSCRIBER_ID"
      appearance={appearance}
    />
  );
}

​

Using Styles Object

You can also use a styles object to style the Inbox components. You can pass the styles directly to the elements object.

import { Inbox } from "@novu/react";

const appearance = {
  elements: {
    bellIcon: {
      padding: "1rem",
      backgroundColor: "white",
      borderRadius: "50%",
    },
    notification: {
      backgroundColor: "white",
      borderRadius: "0.5rem",
      boxShadow: "0 1px 2px 0 rgba(0, 0, 0, 0.05)",
    },
  },
};

export function Novu() {
  return (
    <Inbox
      applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
      subscriberId="YOUR_SUBSCRIBER_ID"
      appearance={appearance}
    />
  );
}

​

Render subject and body with bold text

By default, the Inbox notification text for the subject and body is rendered in a normal font weight. To highlight important words or phrases within your notification messages, you can wrap the desired subject or body text in double asterisks (**). Here’s an example of how you can do this using the Novu Framework:

await step.inApp('inbox', async () => {
  return {
    subject: '**A new member joined the team!**',
    body: '**John Doe** joined the team! Say hello and help them feel at home',
  };
});

Currently we only support bold text. We are working on adding more text formatting options in the future. You can learn more about the Novu Framework in-app step here.

​

Render Notification Component

You can render your own custom notification item component by passing a renderNotification prop to the Inbox or Notifications component, this will allow you to style and render more complex notification items.

<Inbox
  renderNotification={(notification) => {
    return <CustomNotification notification={notification} />;
  }}
/>
