 | This template is used in MediaWiki:Mycustomcssprotected, MediaWiki:Mycustomjsprotected, and MediaWiki:Mycustomjsonprotected. Changes to it can cause immediate changes to the Wikipedia user interface. To avoid major disruption, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them. |
They are displayed when an IP tries to create a JavaScript, CSS or JSON page for their own IP address. This can for example happen if they click a link at Wikipedia:User scripts/List#Installation codes.

Usage:
{{Protected mycustom|pagetype}}
