Properties

Property	Attribute	Description	Type	Default
offset	offset	A number which specifies an offset to add to the root’s bounding box when calculating intersections, effectively shrinking or growing the root for calculation purposes.	number	0
threshold	threshold	Either a single number or an array of numbers which indicate at what percentage of the target’s visibility the observer’s callback should be executed. If you only want to detect when visibility passes the 50% mark, you can use a value of 0.5. If you want the callback to run every time visibility passes another 25%, you would specify the array [0, 0.25, 0.5, 0.75, 1]. The default is 0 (meaning as soon as even one pixel is visible, the callback will be run). A value of 1.0 means that the threshold isn’t considered passed until every pixel is visible.	number \| number[]	0.0
