This Hearthstone application is an example blog website where I practiced using Hearthstone JSON. I found a library of all Hearthstone cards at hearthstonejson.com. I then had to figure out how to make the card image appear when you mouse over the card link. hearthstonejson.com comes with a JSON library and an image library, so I just took advantage of the image library to display the card.
This project also makes use of Google login API. When logged in using the Google service, users can see all of the content in each article. But when they're not logged in, they're only able to see the beginning of the content.
