I have encountered an issue and I have created a JSFiddle to demonstrate it.
Basically, when you click on a paragraph, the 'hidden' class is supposed to be set, triggering a webkit animation that makes the paragraph disappear in 5 seconds.
However, even though the class is set, the animation is not being played as expected.
I feel like I am missing something very basic here.
Can someone please help me figure out what I am doing wrong?
Thank you in advance.
