Expand / shrink div on hover / out with jQuery

Question

I am looking for a jQuery plugin to expand div elements so as to reveal their overflow (if any) on hover. Illustration:

Answer 1

If it is text, it is a little more complicated...

I use it like this:

$('.floating').mouseenter(function(){
  const $this = $(this);
  const dimension = $this.data('dimension');
  const ratioEnlarged = 2;

  const tempElement = $this.clone();
  tempElement.appendTo('body');
  tempElement.css({
    width: dimension.width,
    height: dimension.height
  });

  if(tempElement.is(':offscreen')){
    // Change this to animate if you want it animated.
    $this.css({
      'margin-left': -dimension.width * ratioEnlarged/2,
      'margin-top': -dimension.height * ratioEnlarged/4,
      'font-size': ratioEnlarged + 'em',
      width: dimension.width * ratioEnlarged,
      height: dimension.height * ratioEnlarged
    });
  } else {
    $this.css({
      'margin-left': -dimension.width * ratioEnlarged/4,
      'margin-top': -dimension.height * ratioEnlarged/4,
      'font-size': ratioEnlarged + 'em',
      width: dimension.width * ratioEnlarged,
      height: dimension.height * ratioEnlarged
    });
  }

  tempElement.remove();
});

$('.floating').mouseleave(function(event) {
  const $this = $(this);
  const dimension = $this.data('dimension');

  if(!$this.hasClass('context-menu-active')){
    $this.css({
      margin: 0,
      'font-size': '1em',
      width: dimension.width,
      height: dimension.height
    });
  }
});
