	 *       and document height instead of viewport width and height.
	 *       Default value is false.
	 * offX: x offset of the floating element in the viewport. It can be string or number in number or percent format.
	 *       A parameter in number format means the pixels to the viewport edge.
	 *       A parameter in x% format means the percentage of the viewport width.
	 *       A positive parameter means the offset is relative to the left edge of the viewport.
	 *       A negative parameter means the offset is relative from the right edge of the viewport.
	 *       Note if you want 0 pixel relative to the right edge, you must pass '-0' string as parameter. Because -0 number
	 *       in javascript is same as +0, and will be treated as relavite to the left edge.
	 *       Default value is '-0'.
	 * offY: y offset of the floating element in the viewport. It can be string or number in number or percent format.
	 *       A parameter in number format means the pixels to the viewport edge.
	 *       A parameter in x% format means the percentage of the viewport height.
	 *       A positive parameter means the offset is relative to the top edge of the viewport.
	 *       A negative parameter means the offset is relative to the bottom edge of the viewport. 
	 *       Note if you want 0 pixel relative to the bottom edge, you must pass '-0' string as parameter. Because -0 number
	 *       in javascript is same as +0, and will be treated as relavite to the top edge.
	 *       Default value is '50%'.
	 * spd:  Steps to fufill the floating effect. A smaller value means faster effect. Every step take about 20ms.
