Как сделать переход слайда на CSS?

Question

[Olga]

Есть сайт, где на чистом CSS сделаны слайды как фон сайта. Т.е. фон сайта меняется через несколько секунд. Но сейчас эти слайды меняются с так называемым эффектом fade – как бы растворяясь в новом слайде. А нужно сделать, чтобы слайды просто автоматически листались через 10 секунд, как обычный слайдер.
Помогите, пожалуйста, как это сделать?

transform: translateX() - если горизонтально -100% влево и 100% вправо
transform: translateY() - если вертикально, соответственно.
и вместо процентов в keyframes используй просто from {} и to {}

то есть будет выглядеть
from {transform: translateX(0%);}
to {transform: translateX(-100%);}

Если в процентах не получается, попробуй пиксели
