Question

我想创建一个模态，可以用来显示不确定的加载栏。加载栏是模态中的唯一元素。我希望加载栏垂直居中，但valign-wrapper在这种情况下不起作用。如何使valign-wrapper正常工作？

您可以将进度放置在wrapper标签中，并将其垂直居中：

html：

<div class="progress-wrapper">
  <div class="progress valign">
    <div class="indeterminate" style="width: 50%"></div>
  </div>
</div>

css：

.progress-wrapper {
  position: relative;
  top: 50%;
}

.progress-wrapper .progress {
  margin: 0;
}

物化CSS valign-wrapper在模态中不起作用
