Question

我一直在玩这个CSS3动画，但我不能让它从中间转移到不同的位置。

这是一个动画，从上半部分进入负z轴，下半部分进入正z轴的中间产生类似翻转的效果。

我试图将枢轴点设置为顶部，因此应用此动画的元素将被转换，整个元素将进入正z轴。

然后，flipOut动画就是反过来了。

我很感激任何帮助让这个动画像我描述的那样表现。

这是现在运行动画的代码：

 .animated {
    -webkit-animation-fill-mode: both;
    -moz-animation-fill-mode: both;
    -ms-animation-fill-mode: both;
    -o-animation-fill-mode: both;
    animation-fill-mode: both;
    -webkit-animation-duration: 0.6s;
    -moz-animation-duration: 0.6s;
    -ms-animation-duration: 0.6s;
    -o-animation-duration: 0.6s;
    animation-duration: 0.6s;
}

@-webkit-keyframes flipInX {
    0% {
        -webkit-transform: perspective(400px) rotateX(90deg);
        opacity: 0;
    }

    40% {
        -webkit-transform: perspective(400px) rotateX(-10deg);
    }

    70% {
       -webkit-transform: perspective(400px) rotateX(10deg);
    }

    100% {
        -webkit-transform: perspective(400px) rotateX(0deg);
        opacity: 1;
    }
}
@-moz-keyframes flipInX {

设置transform origin：

transform-origin : center top;

每个MDN文档：

transform-origin: x-offset                                   /* One-value syntax */   E.g.  transform-origin: 2px 
transform-origin: offset-keyword                                                      E.g.  transform-origin: bottom

transform-origin: x-offset y-offset                          /* Two-value syntax */   E.g.  transform-origin: 3cm 2px
transform-origin: y-offset x-offset-keyword                                           E.g.  transform-origin: 2px left
transform-origin: x-offset-keyword y-offset                                           E.g.  transform-origin: left 2px
transform-origin: x-offset-keyword y-offset-keyword                                   E.g.  transform-origin: right top
transform-origin: y-offset-keyword x-offset-keyword                                   E.g.  transform-origin: top right

transform-origin: x-offset y-offset z-offset                 /* Three-value syntax */ E.g.  transform-origin: 2px 30% 10px
transform-origin: y-offset x-offset-keyword z-offset                                  E.g.  transform-origin: 2px left 10px
transform-origin: x-offset-keyword y-offset z-offset                                  E.g.  transform-origin: left 5px -3px
transform-origin: x-offset-keyword y-offset-keyword z-offset                          E.g.  transform-origin: right bottom 2cm
transform-origin: y-offset-keyword x-offset-keyword z-offset                          E.g.  transform-origin: bottom right 2cm
