You can add customizable social media icons to the footer of your website, just below the contact information. This is only available in the _props.pcf file within the root folder for your site or the folder where navigation is restarted.
Each section will pave a _props.pcf file. Settings you choose in a _props.pcf file will carry through to all files and folders within that folder. The _props.pcf file in the site’s root folder includes some additional options.
