Changing Style via CSS

Updating the CSS allows you to change the UI of our components to meet your needs.

This section will guide you through an example of updating the look of buttons. Note that the process can be applied to update any HTML tag from within SuperTokens components.

Global style changes#

How to make changes#

First, let's open our website at /auth. The Sign-in widget should show up. Let's use the browser console to find out the class name that we'd like to overwrite.

Highlighting attribute to be used for customization

Each stylable components contains data-supertokens attributes (in our example data-supertokens="button").

Let's customize elements with the button attribute. The syntax for styling is plain CSS.

import SuperTokens from "supertokens-auth-react";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    style: `
        [data-supertokens~=button] {
            background-color: #252571;
            border: 0px;
            width: 30%;
            margin: 0 auto;
        }
    `,
    recipeList: [ /* ... */]
});

The above will result in:

Prebuilt form with custom submit button

Changing fonts#

By default, SuperTokens uses the Arial font. The best way to override this is to add a font-family styling to the container component in the recipe configuration.

import SuperTokens from "supertokens-auth-react";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    style: `
        [data-supertokens~=container] {
            font-family: cursive;
        }
    `,
    recipeList: [ /* ... */]
});

Using media queries#

You may want to have different CSS for different viewports. This can be achieved via media queries like this:

import SuperTokens from "supertokens-auth-react";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "...",
    },
    style: `
        [data-supertokens~=button] {
            background-color: #252571;
            border: 0px;
            width: 30%;
            margin: 0 auto;
        }

        @media (max-width: 440px) {
            [data-supertokens~=button] {
                width: 90%;
            }
        }
    `,
    recipeList: [ /* ... */],
});

Customising the Sign-Up / Sign-In form#

These are the screens shown when the user tries to log in or sign up for the application.

import SuperTokens from "supertokens-auth-react";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    style: `[data-supertokens~=authPage] {
        ...
    }`,
    recipeList: [ /* ... */]
});

OTP input screen#

This screen is shown if your users are logging in by typing an OTP

import SuperTokens from "supertokens-auth-react";
import Passwordless from "supertokens-auth-react/recipe/passwordless";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    recipeList: [
        Passwordless.init({
            contactMethod: "EMAIL_OR_PHONE", // This example will work with any contactMethod.
            signInUpFeature: {
                userInputCodeFormStyle: ` ... `
            }
        }),
        Session.init()
    ]
});

Link sent screen#

This screen is shown if your users can only log in via a magic link.

import SuperTokens from "supertokens-auth-react";
import Passwordless from "supertokens-auth-react/recipe/passwordless";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    recipeList: [
        Passwordless.init({
            contactMethod: "EMAIL_OR_PHONE", // This example will work with any contactMethod.
            signInUpFeature: {
                linkSentScreenStyle: ` ... `
            }
        }),
        Session.init()
    ]
});

Customizing the Magic Link Clicked Screen#

This screen is shown when the user clicks a magic link.

import SuperTokens from "supertokens-auth-react";
import Passwordless from "supertokens-auth-react/recipe/passwordless";
import Session from "supertokens-auth-react/recipe/session";

SuperTokens.init({
    appInfo: {
        apiDomain: "...",
        appName: "...",
        websiteDomain: "..."
    },
    recipeList: [
        Passwordless.init({
            contactMethod: "EMAIL_OR_PHONE", // This example will work with any contactMethod.
            linkClickedScreenFeature: {
                style: ` ... `
            }
        }),
        Session.init()
    ]
});
