i came across this page online http://www.goal.com/en-us/news/88/spain/2010/11/16/2216717/agent-mino-raiola-barcelona-coach-pep-guardiola-and-johan-cruyff- that has comment ratings . under every post there is a green thumb up and a red thumb down . I would like to know what type of language was used in doing this and also how it was created . to understand better visit the page and scroll down to the comments area then you can see what i am trying to explain better
All kinds of language can do this. You just need to store the number of thumb-ups/downs in your database. Increase the count when someone click the button.
