SharePoint Team Site Branding using Custom Action

SharePoint Teamsite Branding 2

/**********************************************
This script is a Custom Action, that is activated through powershell on each site collection
after it has been provisioned. The custom action is not attached through the master page. 
More info can be found on msdn. 

This custom action is to make sure that when a sub-site is created, it takes on the branding. 
Normally, team sites do not inherit the branding. 

More information found here: https://dcsharepointchick.blogspot.com/2019/04/sharepoint-team-site-branding-and.html
