Я впервые добавляю 3. js, и я просто хочу добавить его на целевую страницу своего веб-сайта. У меня возникает проблема, когда я нажимаю на область сцены, где находится мой объект, страница перемещается вниз. Что я могу сделать, чтобы этого не произошло? Похоже, когда я нажимаю на нее, страница перемещается так, что объект оказывается в центре. Пробовал добавить overflow: hidden; в моем css, но это не работает. Я подозреваю, что мне нужно что-то изменить в коде javascript.
