i dont have any answer with this code

There was no opening or closing body element in the text editor.
The opening tag needs to be above your first div and the closing tag needs to after your last div.
This got it to work.
It’s kind of hard to modify a tag that is not on the page. Or was this part of the problem solving?


First You have to add body element and then add two classes:

$(“body”).addClass(“animated fadeOut”);


The way I solved was to add the body element, as others already mentioned (don’t forget to close it at the bottom), then added the following:

$(“body”).addClass(“animated hinge”);

As I understood the directions the author said to use hinge instead of fadeOut…Cheers.
