Paper 组件的属性也是可用的。

| children | node | The content of the component. | |
| classes | object | Override or extend the styles applied to the component. See CSS API below for more details. | |
| closeText | string | 'Close' | Override the default label for the close popup icon button. For localization purposes, you can use the provided translations. |
| color | 'error' | 'info' | 'success' | 'warning' | string | The color of the component. Unless provided, the value is taken from the severity prop. It supports both default and custom theme colors, which can be added as shown in the palette customization guide. | |
