Почему эта JQuery функция не работает? (Делаем Navbar прозрачным при прокрутке вниз)

0 голосов
/ 18 марта 2020

Я следую учебному пособию. Я не смог понять, почему ни одна из моих JQuery функций не работает. Я прокрутил вниз, и ничего не происходит. Все мои файлы правильно связаны между собой. Я попытался изменить javascript, чтобы прокрутка 50px изменила непрозрачность, но она все равно не работала. Пожалуйста, помогите!

Спасибо за ваше время.

В этой строке отсутствует точка: 

document.querySelector('#navbar')style.opacity = 0.2;

(до "стиля")
