Я пытаюсь реализовать эффект прокрутки липкой карты ⇐ Javascript

[Anonymous]

Я пытаюсь внедрить эффект прокрутки липкой карты, но я сталкиваюсь с некоторыми проблемами и до сих пор не повезло.
Вот конкретные проблемы, с которыми я сталкиваюсь: < /p>
Заголовок «Наш рабочий процесс» не работает, как и предполагалось. Вот скриншот

ни один из карт рабочих потоков или анимированных - они остаются статическими на странице. Ниже приведен фрагмент кода моей текущей реализации (HTML, CSS и JS). < /P>
Я бы очень ценил любое руководство, или если бы кто-то мог бы поделиться рабочей версией такого рода эффекта прокрутки, это было бы невероятно полезно. < /P>
