Note

In Azure Active Directory B2C, custom policies are designed primarily to address complex scenarios. For most scenarios, we recommend that you use built-in user flows. If you've not done so, learn about custom policy starter pack in Get started with custom policies in Active Directory B2C.

You can customize the look and feel of any self-asserted technical profile. Azure Active Directory B2C (Azure AD B2C) runs code in your customer's browser and uses a modern approach called Cross-Origin Resource Sharing (CORS).

To customize the user interface, you specify a URL in the ContentDefinition element with customized HTML content. In the self-asserted technical profile or OrchestrationStep, you point to that content definition identifier. The content definition may contain a LocalizedResourcesReferences element that specifies a list of localized resources to load. Azure AD B2C merges user interface elements with the HTML content that's loaded from your URL and then displays the page to the user.

The ContentDefinitions element contains URLs to HTML5 templates that can be used in a user journey. The HTML5 page URI is used for a specified user interface step. For example, the sign-in or sign-up, password reset, or error pages. You can modify the look and feel by overriding the LoadUri for the HTML5 file. You can create new content definitions according to your needs. This element may contain a localized resources reference, to the localization identifier specified in the Localization element.

The following example shows the content definition identifier and the definition of localized resources:

<ContentDefinition Id="api.localaccountsignup">
  <LoadUri>~/tenant/default/selfAsserted.cshtml</LoadUri>
  <RecoveryUri>~/common/default_page_error.html</RecoveryUri>
  <DataUri>urn:com:microsoft:aad:b2c:elements:selfasserted:1.1.0</DataUri>
  <Metadata>
    <Item Key="DisplayName">Local account sign up page</Item>
  </Metadata>
  <LocalizedResourcesReferences MergeBehavior="Prepend">
    <LocalizedResourcesReference Language="en" LocalizedResourcesReferenceId="api.localaccountsignup.en" />
    <LocalizedResourcesReference Language="es" LocalizedResourcesReferenceId="api.localaccountsignup.es" />
    ...

The metadata of the LocalAccountSignUpWithLogonEmail self-asserted technical profile contains the content definition identifier ContentDefinitionReferenceId set to api.localaccountsignup

<TechnicalProfile Id="LocalAccountSignUpWithLogonEmail">
  <DisplayName>Email signup</DisplayName>
  <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.SelfAssertedAttributeProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
  <Metadata>
    <Item Key="ContentDefinitionReferenceId">api.localaccountsignup</Item>
    ...
  </Metadata>
  ...

ContentDefinition

The ContentDefinition element contains the following attribute:

Attribute Required Description
Id Yes An identifier for a content definition. The value is one specified in the Content definition IDs section later in this page.

The ContentDefinition element contains the following elements:

Element Occurrences Description
LoadUri 1:1 A string that contains the URL of the HTML5 page for the content definition.
RecoveryUri 1:1 A string that contains the URL of the HTML page for displaying an error relating to the content definition. Not currently used, the value must be ~/common/default_page_error.html.
DataUri 1:1 A string that contains the relative URL of an HTML file that provides the user experience to invoke for the step.
Metadata 0:1 A collection of key/value pairs that contains the metadata utilized by the content definition.
LocalizedResourcesReferences 0:1 A collection of localized resources references. Use this element to customize the localization of a user interface and claims attribute.

LoadUri

The LoadUri element is used to specify the URL of the HTML5 page for the content definition. The Azure AD B2C custom policy starter-packs come with content definitions that use Azure AD B2C HTML pages. The LoadUri starts with ~, which is a relative path to your Azure AD B2C tenant.

<ContentDefinition Id="api.signuporsignin">
  <LoadUri>~/tenant/templates/AzureBlue/unified.cshtml</LoadUri>
  ...
</ContentDefinition>

You can customize the user interface with HTML templates. When using HTML templates, provide an absolute URL. The following example illustrates a content definition with HTML template:

<ContentDefinition Id="api.signuporsignin">
  <LoadUri>https://your-storage-account.blob.core.windows.net/your-container/customize-ui.html</LoadUri>
  ...
</ContentDefinition>

DataUri

The DataUri element is used to specify the page identifier. Azure AD B2C uses the page identifier to load and initiate UI elements and client side JavaScript. The format of the value is urn:com:microsoft:aad:b2c:elements:page-name:version. The following table lists the page identifiers you can use.

Page identifier Description
globalexception Displays an error page when an exception or an error is encountered.
providerselection, idpselection Lists the identity providers that users can choose from during sign-in.
unifiedssp Displays a form for signing in with a local account that's based on an email address or a user name. This value also provides the "keep me sign-in functionality" and "Forgot your password?" link.
unifiedssd Displays a form for signing in with a local account that's based on an email address or a username. This page identifier is deprecated. Use the unifiedssp page identifier instead.
multifactor Verifies phone numbers by using text or voice during sign-up or sign-in.
selfasserted Displays a form to collect data from a user. For example, enables users to create or update their profile.

Select a page layout

You can enable JavaScript client-side code by inserting contract between elements and the page type. For example, urn:com:microsoft:aad:b2c:elements:contract:page-name:version.

The version part of the DataUri specifies the package of content containing HTML, CSS, and JavaScript for the user interface elements in your policy. If you intend to enable JavaScript client-side code, the elements you base your JavaScript on must be immutable. If they're not immutable, any changes could cause unexpected behavior on your user pages. To prevent these issues, enforce the use of a page layout and specify a page layout version. Doing so ensures that all content definitions you've based your JavaScript on are immutable. Even if you don't intend to enable JavaScript, you still need to specify the page layout version for your pages.

The following example shows the DataUri of selfasserted version 1.2.0:

<!-- 
<BuildingBlocks> 
  <ContentDefinitions>-->
    <ContentDefinition Id="api.localaccountpasswordreset">
      <LoadUri>~/tenant/templates/AzureBlue/selfAsserted.cshtml</LoadUri>
      <RecoveryUri>~/common/default_page_error.html</RecoveryUri>
      <DataUri>urn:com:microsoft:aad:b2c:elements:contract:selfasserted:1.2.0</DataUri>
      <Metadata>
        <Item Key="DisplayName">Local account change password page</Item>
      </Metadata>
    </ContentDefinition>
  <!-- 
  </ContentDefinitions> 
</BuildingBlocks> -->

Migrating to page layout

To migrate from the old DataUri value (without page contract) to page layout version, add the word contract follow by a page version. Use following table to migrate from the old DataUri value to page layout version.

Old DataUri value New DataUri value
urn:com:microsoft:aad:b2c:elements:globalexception:1.0.0 urn:com:microsoft:aad:b2c:elements:contract:globalexception:1.2.1
urn:com:microsoft:aad:b2c:elements:globalexception:1.1.0 urn:com:microsoft:aad:b2c:elements:contract:globalexception:1.2.1

Content definition IDs

The ID attribute of the ContentDefinition element specifies the type of page that relates to the content definition. The element defines the context that a custom HTML5/CSS template is going to apply. The following table describes the set of content definition IDs that is recognized by the Identity Experience Framework, and the page types that relate to them. You can create your own content definitions with an arbitrary ID.

ID Default template Description
api.error exception.cshtml Error page - Displays an error page when an exception or an error is encountered.
api.idpselections idpSelector.cshtml Identity provider selection page - Lists identity providers that users can choose from during sign-in. The options are usually enterprise identity providers, social identity providers such as Facebook and Google+, or local accounts.
