--description--

You can also target elements by their id attributes.

First target your button element with the id target3 by using the $("#target3") selector.

Note that, just like with CSS declarations, you type a # before the id's name.

Then use jQuery's .addClass() function to add the classes animated and fadeOut.

Here's how you'd make the button element with the id target6 fade out:

$("#target6").addClass("animated fadeOut");

--hints--

You should select the button element with the id of target3 and use the jQuery addClass() function to give it the class of animated.

assert($('#target3').hasClass('animated'));

You should target the element with the id target3 and use the jQuery addClass() function to give it the class fadeOut.

assert(
  ($('#target3').hasClass('fadeOut') || $('#target3').hasClass('fadeout')) &&
    code.match(/\$\(\s*.#target3.\s*\)/g)
);

You should only use jQuery to add these classes to the element.

assert(!code.match(/class.*animated/g));
