Creates a swing animation on focus.

• Use an appropriate transition to animate changes to the element.
• Use the :focus pseudo-class to apply an animation that uses transform to make the element swing.
• Use animation-iteration-count to only play the animation once.

<button class="button-swing">Submit</button>
