 * Hello, am using Twenty Twenty one theme, with Options for Twenty Twenty One plugin.
   I have added the social icons for FB and Instagram, to the footer widget area,
   and I would like to add Substack icon too. But it doesn’t seem to exist in the
   list of icons. I have the icon downloaded but I am not able to upload it to the
   widget area. Help please. Thank you very much in advance. Angela.

 * You’re using the Social Icons block in that spot. It offers a large—though not
   infinite—selection of platforms. See: [https://wordpress.org/documentation/article/social-icons/](https://wordpress.org/documentation/article/social-icons/)
   
   However, there are several ways to use an icon that isn’t included in the list:
   a) You could select a different platform and customize its icon with custom CSS.
   Example:
 *     ```wp-block-code
       .wp-social-link-behance svg { display: none }.wp-social-link-behance a { background-image: url(your-custom-image); background-repeat: no-repeat; display: inline-block;}
       ```
   
 * b) Here’s a guide on how to add custom icons using code: [https://developer.wordpress.org/news/2025/08/registering-custom-social-icons-in-wordpress-6-9/](https://developer.wordpress.org/news/2025/08/registering-custom-social-icons-in-wordpress-6-9/)
   
   c) You could also use a plugin that lets you add social icons and offers the 
   one you’re looking for. I can’t think of one off the top of my head, but take
   a look at this: [https://wordpress.org/plugins/simple-social-icons/](https://wordpress.org/plugins/simple-social-icons/)

 * Thank you, I have found a plugin that gives me Substack icon in the Socials block,
   so that’s sorted it. thank you.
