## Description
|
||
<section id='description'>
|
||
Вы также можете настраивать элементы по их атрибутам id. Сначала <code>target3</code> элемент <code>button</code> с <code>target3</code> с помощью селектора <code>$("#target3")</code> . Обратите внимание, что, как и в объявлениях CSS, вы вводите <code>#</code> перед именем id. Затем используйте <code>.addClass()</code> jQuery для добавления классов <code>animated</code> и <code>fadeOut</code> . Вот как вы делаете элемент <code>button</code> с id <code>target6</code> исчезающим: <code>$("#target6").addClass("animated fadeOut")</code> .
