I am trying to understand the different rules of EasyList of Adblock Plus but have not been able to find a definitive guide. Could someone point me to the right place or describe the different rules and symbols, e.g., #, ##, ###, $, @@, ||, ^, and so on? When is the matching done with url, and when is it done with class and id attributes? Which rules define whitelists and which ones define blacklists?
Found it at https://web.archive.org/web/20190524175247/https://adblockplus.org/en/filters. The page describes the different types of filters as well as tips for creating them.
