Гайд по компоненту с названием аккордеон

Задача

Аккордеон в веб приложениях служит для компактного хранения текста. Создадим такой компонент интерфейса с помощью css и html. Хорошая практика заключается в том, что бы правильно создать структуру документа html. Каждый текст должен относится к своему родительскому блоку. Подключаем css и аккордеон готов!
