Type declaration ​

angle ​

angle: string

The angle at which a linear gradient moves. Specify the angle using an integer value like 90deg (90 degrees) or a decimal number like 23.5deg (23.5 degrees) in the half-open interval [0, 360). The direction of the linear gradient rotates clockwise as the angle increases. Given a value of 0deg, the gradient starts at the bottom and ends at the top; given a value of 45deg, the gradient starts at the bottom-left corner and ends at the top-right corner; given a value of 90deg, the gradient starts at the left and ends at the right; and given a value of 180deg, the gradient starts at the top and ends at the bottom. For more information, see Direction (angle) of linear gradient backgrounds in the Messaging API documentation.

centerColor? ​

optional centerColor: string

The color in the middle of the gradient. Use a hexadecimal color code in the #RRGGBB or #RRGGBBAA format. Specify a value for the background.centerColor property to create a gradient that has three colors. For more information, see Intermediate color stops for linear gradients in the Messaging API documentation.

centerPosition? ​

optional centerPosition: string

The position of the intermediate color stop. Specify an integer or decimal value between 0% (the starting point) and 100% (the ending point). This is 50% by default. For more information, see Intermediate color stops for linear gradients in the Messaging API documentation.

endColor ​

endColor: string

The color at the gradient's ending point. Use a hexadecimal color code in the #RRGGBB or #RRGGBBAA format.

startColor ​

startColor: string

The color at the gradient's starting point. Use a hexadecimal color code in the #RRGGBB or #RRGGBBAA format.
