css - React：使盒子大小相同，即使内容不同

Question

我写了一个网站，你可以在这里看到：https ://konekto.world/

入职后，您会注意到几乎白色外框的大小在每个屏幕上都不同（尤其是在https://konekto.world/emergency_details上）。我想为盒子设置一个固定的高度（我什至可能想让它取决于屏幕尺寸）。你能帮我在我的代码中的什么地方以及如何使代码的大小相同。到目前为止我所做的具有以下效果：https ://konekto-k8x5umx6o.now.sh

}
export default withRouter(withStyles(styles)(SOS));
//   <Container component="main" maxWidth="sm">

我有条件地渲染 FormPersonType、FormEmergencyType 和 Textbox，但它们不包含任何样式。

谢谢您的帮助！

Answer 1

添加min-height: 60vh, 而不是height: 60%, 这将与固定高度一起使用。

也适用于容器子修复：

  .containerWhenIPhone{
    overflow: auto;
    box-sizing: content-box;
  }
