预计背景图像是正确的,但它是横向倒置的

双方旋转180度的问题。正面是正确的 — 它应该从 0 度开始,然后过渡到 180 度。但侧应该从180开始,然后过渡到0。从逻辑上讲,这是有道理的,因为在现实生活中,如果您正常拿着一张卡片,正面会旋转 0 度,因为它面向您,而背面会旋转 180 度,因为它背对您。

您可以通过为正面和背面添加单独的悬停状态来解决此问题,使正面从 0 旋转到 180,而背面从 -180 旋转到 0(负值,以便两侧沿相同方向旋转)。

.card .front {
    background: url(images/FRONT.png) no-repeat center center;
    background-size: cover;
    backface-visibility: hidden;
    /* z-index: 1; */
    transform: rotateY(0deg);
}

.card .back {
    background: url(images/a_dark_background_with_a_computer_and_a_.png) no-repeat center center;
    z-index: -1;
    transform: rotateY(-180deg);
}

.card:hover .front {
    transform: rotateY(180deg);
}

.card:hover .back {
    transform: rotateY(0deg);
}
