-|**disabled**          |`Boolean`             |`false`   |Determines if the component will have parallax offsets applied. If `true` parallax styles are completely removed from the element and it is no longer updated.
-|**offsetXMax**        |`Number` or `String`  |`0`       |Maximum **x** offset in `%` or `px`. If no unit is passed percent is assumed. Percent is based on the elements width.
