Fill Gradient Type
fill-gradient-type
Determines the gradient direction of fill=gradient.
Valid values are linear and radial. Defaults to linear when not specified.
linear(default): Generates the gradient in a linear direction (ex: left to right). Colors can be controlled with fill-gradient-linearradial: Sets the gradient to have a radial direction (ex: from center outwards). Colors can be controlled with fill-gradient-radial
