Танцующая новогодняя ёлочка для сайта
Умей ценить того кто без тебя не может, и не гонись за тем, кто счастлив без тебя!
6-декабря-2023, 21:37 4 0
Интересное решение анимированной елочки для сайта. Елочку можно вращать, она в 3D исполнении, так же по клику начинает играть музыка.
Можно украсить веб проект, может кому и пригодиться. Всех с наступающими праздниками!!!
