I need help with  I want the background of the box surrounding "Administrator" filled in but I don't know what's wrong with the coding:

body.ns-1201 .edited-by > a.subtle[href$="/wiki/User_talk:Not_David_Brown"]:after { content: "Administrator"; border-radius: 10px; border: 3px solid green; padding: 3px 6px; color: black; background: solid green; }
