改变棘轮模态尺寸和滑动位置

Question

如何更改棘轮模态，使其从顶部向下滑动并且只占据屏幕的 50% 而不是整个高度？

模态的 css 是；

.modal {
  position: fixed;
  top: 0;
  z-index: 11;
  width: 100%;
  min-height: 100%;
  overflow: hidden;
  background-color: #fff;
  opacity: 0;
  -webkit-transition: -webkit-transform .25s, opacity 1ms .25s;
     -moz-transition:    -moz-transform .25s, opacity 1ms .25s;
          transition:         transform .25s, opacity 1ms .25s;
  -webkit-transform: translate3d(0, 100%, 0);
      -ms-transform: translate3d(0, 100%, 0);
          transform: translate3d(0, 100%, 0);
}
.modal.active {
  height: 100%;
  opacity: 1;
  -webkit-transition: -webkit-transform .25s;
     -moz-transition:    -moz-transform .25s;
          transition:         transform .25s;
  -webkit-transform: translate3d(25%, 0, 0);
      -ms-transform: translate3d(25%, 0, 0);
          transform: translate3d(25%, 0, 0);
}

我一直在尝试不同的值，但无法如愿以偿。

我很确定这很接近，但目前无法真正测试它。

transform: translate3d(0,-100%,0); 应在屏幕顶部启动模态框，transform: translate3d(0,50%,0); 应在活动时将其移动到中间。然后明显的高度变为50%...

.modal.active {
    height: 50%;
    opacity: 1;
    -webkit-transition: -webkit-transform .25s;
    -moz-transition: -moz-transform .25s;
    transition: transform .25s;
    -webkit-transform: translate3d(0,50%,0);
    -ms-transform: translate3d(0,50%,0);
    transform: translate3d(0,50%,0);
}

.modal {
    position: fixed;
    top: 0;
    z-index: 11;
    width: 100%;
    min-height: 50%;
    overflow: hidden;
    background-color: #fff;
    opacity: 0;
    -webkit-transition: -webkit-transform .25s,opacity 1ms .25s;
    -moz-transition: -moz-transform .25s,opacity 1ms .25s;
    transition: transform .25s,opacity 1ms .25s;
    -webkit-transform: translate3d(0,-100%,0);
    -ms-transform: translate3d(0,-100%,0);
    transform: translate3d(0,-100%,0);
}
