...t handler is then set up. it simply sets the box's animation-play-state to "paused", then updates the text displayed in the button to indicate that clicking the button will start playing the next iteration of theanimation. finally, we set up a handler for a click on the button that runs the animation: document.getelementbyid("play").addeventlistener("click", function(event) { box.style.animationplaystate = "running"; iterationcounter++; }, false); this sets the box element's animation-play-state to "running" and increments the iteration counter. that's all there is to it! result assembled together, you get this: each time the box reaches the opposing corner, it stops, with the button reflecting which iteration number is up next, until you click the button to run the next iteration. ...
