Ще ви покажа един от начините да внесете динамика в училищния сайт.
С готов скрипт може да добавите ефект с падащи сърчица и с водни балончета.
Достатъчно е да копирате кода с бутона Embed code от Widget :

Сърчица след курсора - нагледен пример:

С червен цвят съм отбелязал цвета, който може да промените.

Изглежда дълго, но в крайна сметка е едно copy-paste. Качени на хост не работят коректно, а и в този вид си гарантирате, че ще се изпълнят независимо от коя точка на света ще се отвори сайта.

Ако има въпроси съм насреща. Слънчева седмица : )
