Defaults

The Framer.Defaults allows you to override the default properties for Layers and Animations when they are created. For example, all new layers get a light blue background color so you can see them. You can override that color here.
译：Framer.Defaults允许你在一开始就默认覆盖图层和动画的一些属性。比如说，你想让所有图层背景都是浅蓝色以便看见它们，你就可以用这个颜色覆盖它的背景色属性。

# Override the default background color for layers 
Framer.Defaults.Layer.backgroundColor = "red"

# Override the default corner radius for layers 
Framer.Defaults.Layer.borderRadius = 10

layerA = new Layer

print layerA.backgroundColor
# Output: "red" 

print layerA.borderRadius
# Output: 10

Here is an example to set the default animation curve. Note that those will also be used for layer.states switches unless you override them for that layer with layer.states.animationOptions.
译：这个例子是设置默认动画曲线。需要注意的是layer.states的改变也会遵循该曲线，除非你是用layer.states.animationOptions来定义的。

# Override the default animation options for all Animations 
Framer.Defaults.Animation =
    curve: "spring(100,10,0)"

# Override the default corner radius for layers 
Framer.Defaults.Layer.borderRadius = 10

layerA = new Layer

layerA.animate
    properties:
        x: 100

# The animation will now use the "spring(100,10,0)" curve
