 Allows you to control the `threshold` property of the underlying `IntersectionObserver`:
 
-This value should be a decimal in the range "0-1". A value of "0" means: trigger an "intersection" if ANY part of the element enters the viewport (the default behavior). While a value of "1" means: don't trigger an "intersection" unless the entire element has entered the viewport.

 For example if you want to trigger an intersection after half of the element has entered the page, you can use `.threshold.50`:
