Question

我为Bootstrap创建了一个旋转木马模态，无论屏幕尺寸如何，或者例如移动屏幕垂直倾斜，我都无法弄清楚如何正确居中。

我现在拥有的CSS代码正确地将模态放在普通的电脑屏幕上，但它在移动屏幕上不起作用，并且MOdal出现在屏幕的顶部而不是出现在它应该的中间。

position

，也不垂直对齐为我工作。

＆＃13;

.modal {
  vertical-align: middle;
  padding-left: 5%;
  padding-left: 5%;
  padding-top: 1%;
  text-align: middle;
  max-height: 90vh;
  max-width: 95vw;
}

.modal .carousel-inner {
  max-height: 100% ! important;
  position: center;
  text-align: middle;
  vertical-align: middle;
}

.modal .carousel .item @media (max-width: 991px) {
  .modal {
    padding-top: 55%;
  }
}
