Hi Trying to figure out what I am doing wrong with this pen: http://codepen.io/nushi/pen/MKjQPK I want to pass the properties for the timeline animation through a function's arguments. Passing in the element that is being animated is not the problem. Where I am stumped is with the property. The function has a .from animation. The starting position is what I want to pass as a variable. As you can see in my codepen, and below, I attempted to do this by declaring the CSS position in a var and then converting that CSS position into something that can be used in the timeline and passed as into the function (startPos). What I am doing does not work .... Any better ideas on how to achieve this? Thanks!!
