##### Enabling Notification
Before publishing a notification, check whether the notification feature is enabled for your application. By default, the feature is disabled. The application calls **Notification.requestEnableNotification** to prompt the user to enable the feature.

##### Publishing Notifications
Before publishing a notification, check whether the notification feature is enabled for your application. By default, the feature is disabled. You can enabled it in notification settings.

## Designing Static Animation
Create a square and rotate it by 90 degrees to form a rhombus. Cover the lower part of the rhombus with a rectangle to form a roof. Set the translate attribute of the rectangle to the coordinate (150px, -150px) to form a door, use the position attribute to translate the horizontal and vertical axes to the specified coordinates of the parent component (square), set the scale attribute to scale up the parent and child components together to determine the window size, and use the skewX attribute to skew the component and set the coordinate translate(200px,-830px) to form a chimney.

## Designing Scaling Animation
This example implements a ripple animation with the scale attribute. Here is the overall procedure: First, use the positioning function to determine the coordinates of the element's position. Then, create multiple components to achieve the overlapping effect. After that, set the opacity attribute to hide or display the components. To scale and hide/display a component at the same time, set both the scale and opacity attributes. Finally, set different animation durations for different components to achieve the diffusion effect.
Set the scaling values for the x-axis, y-axis, and z-axis in scale3d to implement the animation.

## Setting matrix
The matrix attribute defines a transformation matrix with six input parameters: scaleX, skewY, skewX, scaleY, translateX, and translateY. In the following example, matrix is set to matrix(1,0,0,1,0,200) to skew and translate the component.
