Я создал (нравится и не нравится) в моем проекте, и мне это нужно, когда кто-то нажимает на кнопку. цвет изменится на синий
Я видел что-то подобное, где я мог создать переменную с названием что-то вроде: is_liked = False, и я могу поместить это в HTML по контексту, чтобы вызвать ее (если условие), но это не работает со мной так, как я могу запустить цвет на кнопке Like?

как я могу поставить условие на странице HTML, чтобы проверить, является ли is_liked истинным или ложным?
