I've updated your fiddle to show the changes.

Basically, add a .active class to your CSS, and then add the active class to the clicked button and remove it from the others.

You should probably look at refactoring your code so that you only have one click event. You seem to be replicating a lot of your code:

Here's another update to the fiddle, that reduces the click event to just one. The event is bound to your buttons (with a class of showDiv) and it shows div that's stored in the data-div attribute of each button
