Customize the look and feel of a copilot
Your copilot's canvas determines its look and feel. You can customize the canvas in two ways, depending on the complexity of the desired changes:
Customize the default canvas with JavaScript styling in the HTML code of the website where you deploy your copilot.
This approach is useful if you want to make small customizations without investing in code development.Use a custom canvas that's based on the Bot Framework Web Chat canvas.
This approach requires extensive developer knowledge. It's useful for organizations that want a completely custom experience.
Important
You may install and use the sample code included in this article only for use with Microsoft Copilot Studio. The sample code is licensed "as is" and is excluded from any service level agreements or support services. You bear the risk of using it.

After you create and publish a copilot, your customers can use the copilot's Web Chat canvas to interact with it.
You can also combine the customized canvas with configuring your copilot to automatically start the conversation.
Lastly, you can change the name and icon of your copilot (when it's shared in Microsoft Teams) directly from the portal.
Change the copilot name and icon
Important
If your copilot is connected to Omnichannel for Customer Service, its name is defined by the Display name property in the Azure portal registration.
You can change the copilot's name and icon. This will affect the icon in all channels where you publish your copilot.
In the navigation menu, under Settings, select Details.
Change the copilot's name and icon. Review the recommendations on Microsoft Teams icon formats.
Select Save to commit your changes.
Important
After updating your copilot's icon, it may take up to 24 hours for the new icon to appear everywhere.
Retrieve token endpoint
To customize your canvas, whether it's the default canvas or a custom one you connect to, you need to retrieve your copilot details.
In the navigation menu under Settings, select Channels.
Select Mobile app.
Next to Token Endpoint, select Copy.
Customize the default canvas (simple)
Configure how the chat canvas looks with some simple CSS and JavaScript styling options.
First, you need to configure where you're deploying your copilot canvas.
Copy and paste the HTML code below and save it as index.html.
You can also copy and paste the code below into the w3schools.com HTML try it editor. You'll still need to add your token endpoint.<!doctype html> <html lang="en"> <head> <title>Contoso Sample Web Chat</title> <!-- This styling is for the Web Chat demonstration purposes. It is recommended that style is moved to a separate file for organization in larger projects. Please visit https://github.com/microsoft/BotFramework-WebChat for details about Web Chat. --> <style> html, body { height: 100%; } body { margin: 0; } h1 { color: whitesmoke; font-family: Segoe UI; font-size: 16px; line-height: 20px; margin: 0; padding: 0 20px; } #banner { align-items: center; background-color: black; display: flex; height: 50px; } #webchat { height: calc(100% - 50px); overflow: hidden; position: fixed; top: 50px; width: 100%; } </style> </head> <body> <div> <div id="banner"> <h1>Contoso copilot name</h1> </div> <div id="webchat" role="main"></div> </div> <!-- In this sample, the latest version of Web Chat is being used.

const tokenEndpointURL = "<YOUR TOKEN ENDPOINT>";.Open index.html using a modern browser (for example, Microsoft Edge) to open the copilot in the custom canvas.
Test the copilot to ensure you are receiving responses from it and that it's working correctly.
If you encounter problems, make sure you've published your copilot, and that your token endpoint has been inserted in the correct place. It should be after the equals sign (=) at the line
const tokenEndpointURL = "<YOUR TOKEN ENDPOINT>", and surrounded by double quotation marks (").
Customize the copilot icon, background color, and name
Once you get the customized canvas working with your copilot, you can make changes to it.
You can use the JavaScript styleOptions options to configure a number of predefined styles.
See Web Chat customization for links to the defaultStyleOptions.js file and more information on what you can customize and how it will look.
Change the copilot icon
Update the index.html file with the following sample code:
const styleOptions = { accent: '#00809d', botAvatarBackgroundColor: '#FFFFFF', botAvatarImage: 'https://learn.microsoft.com/azure/bot-service/v4sdk/media/logo_bot.svg', botAvatarInitials: 'BT', userAvatarImage: 'https://avatars.githubusercontent.com/u/661465' };Replace the copilot and user avatar images with your company images.
If you don't have an image URL, you can use a Base64-encoded image string instead.
Change the background color
Update the index.html file with following sample code:
const styleOptions = { backgroundColor: 'lightgray' };Change
backgroundColorto any color you wish. You can use standard CSS color names, RGB values, or HEX.
Change the copilot name
Update the
<h1>text in the index.html file with the following:<body> <div id="banner"> <h1><img src="contosocopilot-teams.png"> Contoso copilot name</h1> </div>Change the text to whatever you want to call the copilot. You can also insert an image, although you may need to style it to ensure it fits within the heading section.
Customize and host your chat canvas (advanced)
You can connect your Copilot Studio copilot with a custom canvas that is hosted as a standalone web app. This option is best if you need to embed a customized iFrame across multiple web pages.
Note
Hosting a custom canvas requires software development. Our guidance here is intended for experienced IT professionals, such as IT admins or developers who have a good understanding of developer tools, utilities, and IDEs.
Pick a sample to customize
We recommend starting with one of these samples custom-built to work with Copilot Studio:
Full bundle is a custom canvas capable of showing all rich content from Copilot Studio. For example:
Location and file uploading is a custom canvas capable of getting a user's location and sending it to a Copilot Studio copilot. For example:
Or you can pick from other sample Web Chat canvases provided by Bot Framework.
Customize canvas using styleSetOptions
As with customizing the default canvas, you can use styleSetOptions to customize the custom canvas. All customizable properties are listed in defaultStyleOptions.js. For more information on what you can customize and how it will look, see Web Chat customization.
Deploy your customized canvas
In order to host your custom canvas, deploy all files to a web app.
