Я создаю сайт Google, но, к сожалению, Google не предлагает готовое слайд-шоу для добавления фотографий. Я гуглил и нашел w3schools "How TO - Галерея слайд-шоу (https://www.w3schools.com/howto/howto_js_slideshow_gallery.asp).). Я взял это и заменил изображения своими ссылками и сделал несколько незначительных изменений (которые я прокомментировал в коде как" HELLO Я НОВЫЙ или ИЗМЕНЕННЫЙ "). Поскольку мои фотографии не были одинаковыми по бокам, друг помог мне узнать, как применять объектную подгонку, чтобы они отображались равномерно, не заставляя страницу прыгать вверх и вниз.
ОДНАКО, я хотел больше, чем 6 оригинальных слайдов в галерее, поэтому я добавил больше div для слайдов и галереи ниже. Где-то в этом процессе заставляет Chrome периодически мигать черным . Я возился с этим, но просто не могу понять, почему он не остановит отключение браузера. Я довольно новичок в кодировании, не могу понять это и не знаю точно, что даже искать, чтобы попытаться понять это. Спасибо за любую помощь, которую вы можете предоставить.
Вот мой код:
