Syntax

myFx.toElementEdge(el[, axes[, offset]]);

Arguments

1. el - (mixed) A string of the Element's id or an Element reference to scroll to.
2. axes - (array or string, optional) An array or string specifying which axes to scroll on, can be 'x', 'y', or ['x', 'y']. It defaults to both axes.
3. offset - (object, optional) An object specifying which axes should get an offset. Examples: {x: 0; y: 100}, {y: 100}.
