The radius of the rounded corners is subject to the component size. Its maximum value is half of the component width or height. If the value is negative, the default value is used.

You can set the width for all four sides or set separate widths for individual sides.
Default value: **0**
When set to a percentage, the value defines the border width as a percentage of the parent dialog box's width.
If the left and right borders are greater than its width, or the top and bottom borders are greater than its height, the dialog box may not display as expected.|

| width12+ | [Dimension](ts-types.md#dimension10) | No| Width of the dialog box.
**NOTE**
- Default maximum width of the dialog box: 400 vp
- When this parameter is set to a percentage, the reference width of the dialog box is the width of the window where the dialog box is located. You can decrease or increase the width as needed.|
| height12+ | [Dimension](ts-types.md#dimension10) | No| Height of the dialog box.
**NOTE**
- Default maximum height of the dialog box: 0.9 x (Window height – Safe area)

| transition12+ | [TransitionEffect](ts-transition-animation-component.md#transitioneffect10) | No| Transition effect for the entrance and exit of the dialog box.
**NOTE**
1. If this parameter is not set, the default effect is used.
2. Touching the Back button during the entrance animation pauses the entrance animation and starts the exit animation. The final effect is one obtained after the curves of the entrance and exit animations are combined.
3. Touching the Back button during the exit animation does not affect the animation playback. Touching the Back button again closes the application.|
