How to Add a Facebook Button on Your Site

If you want to add a Facebook button to your website, you can follow these steps:

1. Go to the Facebook developer website and log in using your Facebook account.

2. Create a new app by clicking on the "Create App" button on the top right corner of the screen. Give your app a name and select the category that best describes your app.

3. Once your app is created, you will be redirected to the app dashboard. Click on the "Add Product" button on the left-hand side of the screen and select "Facebook Login".

4. In the "Facebook Login" section, click on the "Set Up" button next to "Web".

5. Enter the URL of your website and click on the "Save" button.

6. Now, you need to copy the App ID and paste it into your website's HTML code. To do this, you can use the following code:

```

<script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v12.0&appId=YOUR_APP_ID&autoLogAppEvents=1" nonce="YlvcirKf"></script> ```

Make sure to replace "YOUR_APP_ID" with the App ID you copied from the Facebook developer website.

7. Next, you can add the Facebook button to your website using the following code:

```

```

Again, make sure to replace "https://yourwebsite.com" with the URL of your website.

8. Finally, save your changes and refresh your website to see the Facebook button.

Note that you may need to customize the button's appearance and behavior using CSS and JavaScript. You can refer to the Facebook developer website for more information on how to do this.
