Страница вопрос-ответ (FAQ)

Реализация адаптивной под мобильные разрешения экранов страницы Вопрос-ответ (FAQ).

Как реализовать:

1. Разметка html

<section class="cd-faq">
	<ul class="cd-faq-categories">
		<li><a href="#basics">Basics</a></li>
		<li><a href="#mobile">Mobile</a></li>
		<li><!-- ... --></li>
	</ul>

	<div class="cd-faq-items">
		<ul id="basics" class="cd-faq-group">
			<li class="cd-faq-title"><h2>Basics</h2></li>
			<li>
				<a class="cd-faq-trigger" href="#0">How do I change my password?</a>
				<div class="cd-faq-content">
					<!-- content here -->
				</div>
			</li>

			<li>
				<a class="cd-faq-trigger" href="#0">How do I sign up?</a>
				<div class="cd-faq-content">
					<!-- content here -->
				</div>
			</li>

			<li><!-- ... --></li>
		</ul>

		<ul id="mobile" class="cd-faq-group">
			<!-- ... -->
		</ul>

		<!-- ... -->
	</div>
</section>

При добавлении новой секции с вопросом-ответом мы добавляем вот такой блок:

		<ul id="mobile" class="cd-faq-group">
			<!-- ... -->
		</ul>

И пункт в меню:

		<li><a href="#mobile">Mobile</a></li>

2. Добавим стили CSS

3. Подключаем javascript и jQuery

<script src="js/jquery-2.1.1.js"></script>
<script src="js/jquery.mobile.custom.min.js"></script>
<script src="js/main.js"></script> 

Готово!
