As a global or SharePoint admin in Microsoft 365, you can allow custom script as a way of letting users change the look, feel, and behavior of sites and pages to meet organizational objectives or individual needs. If you allow custom script, all users who have “Add and Customize Pages” permission to a site or page can add any script they want.
Can a script be added to a SharePoint site?
For simple ways to change the look and feel of a site, see Change the look of your SharePoint site. By default, script is allowed on most sites that admins create. It is not allowed on OneDrive, on sites users create themselves, on modern team and communication sites, and on the root site for your organization.
Because self-service site creation points to your organization’s root site by default, changing the Custom Script setting allows custom script on your organization’s root site. For info about changing where sites are created, see Manage site creation in SharePoint. Select OK. It can take up to 24 hours for the change to take effect.
What happens if custom script is blocked in SharePoint?

Can a custom script be run on a personal site?
Allow users to run custom script on personal sites. Allow users to run custom script on self-service created sites. Because self-service site creation points to your organization’s root site by default, changing the Custom Script setting allows custom script on your organization’s root site.
