Question

我正在尝试使用Bootstrap html页面，将正文放大90％。Bootstrap模式显示的是右侧和底部的空格。为了显示该问题，我将一个带模式的基本html页面置于主体90％缩放状态。

当您单击打开的模态时，您将在模态的右边和底部看到空格。.我们如何使用主体缩放90％渲染不带有多余空格的模态。所需的输出是模态模糊背景应覆盖整个屏幕。。和模式主体应位于x轴的中心，就像90％和100％的缩放比例一样，只是90％的缩放比例是小字体

Answer 1

class .modal-backdrop使用100vh和100vw，由于我们应用了90％缩放，所以100vh对应于屏幕高度的90％； 100vw相当于屏幕宽度的90％；

解决方案：使用width: 100%; height: 100%;

覆盖此类

.modal-backdrop {
  width: 100% !important;
  height: 100% !important;
}
