Style

The style manages the general visual properties applied to this node.

Background

Control the background (image, color, or gradient) of the node.

Opacity

Control the opacity of the node.

Rounding

Controls the radius of the rounded outer corners of the node. You can set the radius for all corners (top left, top right, bottom left, bottom right) or for each corner individually.

Border

Controls the shape, color and thickness of the node's border.

Thickness**: The thickness of the border. You can set the thickness for all borders (top, left, right, bottom) or for each one individually.
Shape** : the style of the border.
Color** : the color of the border.

Shadows

Allows you to add one or more shadows to a node. Each shadow is defined by :

type** : whether the shadow is inside or outside the node box.
x:** specifies the horizontal distance. Negative values place the shadow to the left of the element.
y** : specifies the vertical distance. Negative values place the shadow above the element.
blur** : the larger this value, the more blurred the shadow becomes, so it is larger and lighter.
Dispersion**: positive values make the shadow expand and grow, negative values make the shadow shrink.

Blur

Applies blur to the background of the node only, to create an iOS-style glass effect. The larger the value, the greater the blur.

Layout

The layout allows you to place and position your node in relation to its siblings (those of the same parent node).

Width

Controls the width of the node.

px** : defines the width of the node in pixels.
%** : sets the width of the node as a percentage of the width of its parent.
fit**: automatically adjusts the width of the node according to the width of its content.
grow** : specifies how much of the parent's remaining space should be allocated to the node.

Height

px** : defines the height of the node in pixels.
% : defines the height of the node as a percentage of the width of its parent.
fit** : automatically determines the height of the node according to the width of its content.
grow** : specifies how much of the parent's remaining space should be allocated to the node.
