API will return PlayerID and Point we need to put it on leaderboard table which rank and prize is added
we should be able to choose get information for next day or previous day or next week and previous week

you need to design full responsive design for table and shows the corresponding data according to visitor's choice
To achieve this, created what WordPress calls a child theme.
