## Description
< section id = 'description' >
You can also target elements by their id attributes.
First target your < code > button< / code > element with the id < code > target3< / code > by using the < code > $("#target3")< / code > selector.
Note that, just like with CSS declarations, you type a < code > #< / code > before the id's name.
Then use jQuery's < code > .addClass()< / code > function to add the classes < code > animated< / code > and < code > fadeOut< / code > .
Here's how you'd make the < code > button< / code > element with the id < code > target6< / code > fade out:
< code > $("#target6").addClass("animated fadeOut")< / code > .
