How would I animate an element in from offscreen (just outside the left and right side of the browser) and into it's initial position?   It has a position center screen initially ... and need to have in relation to other elements. I'm thinking; Oh, how do I get the right viewport position and add the width of the element to push it offscreen for that amount. But that seems kind of like rocket science ... I guess there has to be a simpler way? See the Pen ZELQYop by
