Elastic SVG Modal Window with jQuery and Snap.svg

A fancy elastic morphing modal window with SVG shape animations built on top of jQuery and Snap.svg. Inspired by codrops' Elastic SVG Elements.

How to use it:

1. Include the necessary jQuery and Snap.SVG javascript libraries on the html page.

<script src="/path/to/jquery-2.1.4.min.js"></script>
<script src="/path/to/snap.svg-min.js"></script>

2. Create a SVG modal window with a close button as follow.

<div id="modal" class="modal">
    <button id="modal-close" class="modal-close">Close</button>
    <div id="svg-wrapper" class="svg-wrapper" data-btn-hovered="M1220.267,723.2c0,0-293.547,0-580.267,0c-333.653,0-584.533,0-584.533,0s0-104.783,0-334.854

      <svg id="svg" width="100%" height="100%" viewBox="0 0 1280 800"  preserveAspectRatio="none">
        <path id="svg-path" d="M1220.267,723.2c0,0-293.547,0-580.267,0c-333.653,0-584.533,0-584.533,0s0-3.505,0-11.2

      </svg>
    </div>
</div>

3. Create a link to launch the modal window.

<a href="#" class="btn btn-show-overlay">Lauch a modal</a>

4. The core CSS styles.

.svg-wrapper {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
}

.svg-wrapper svg {
  width: 100%;
  height: 100%;
  overflow: hidden;
}

path {
  fill: #2e2e2e;
  stroke: #2e2e2e;
  stroke-width: 1px;
}

.modal {
  position: relative;
  margin: 0 auto;
  width: 250px;
  height: 105px;
  -webkit-transition: height 0.6s, width 0.6s;
  transition: height 0.6s, width 0.6s;
}

.modal-close {
  display: none;
  position: absolute;
  text-transform: uppercase;
  top: 65px;
  right: 85px;
  color: white;
  z-index: 10;
  border: none;
  background-color: transparent;
  border-bottom: 2px solid transparent;
}

.modal-close:hover, .modal-close:focus { border-bottom-color: white; }

.modal-active .modal {
  width: 100%;
  height: 630px;
}

.modal-active .btn { display: none; }

.modal-active .modal-close { display: block; }

5. The JavaScript to active the modal window.

(function () {
  var svgModal = {
      showOverlay: $('.btn-show-overlay'),
      closeOverlay: $('#modal-close'),
      modal: $('#modal'),
      svgWrapper: $('#svg-wrapper'),
      pathElement: undefined,
      modalOpen: false,
      btnHovered: false,
      paths: {
          default: $('#svg-path').attr('d'),
          active: $('#svg-wrapper').data('btn-hovered'),
          modalOpen: $('#svg-wrapper').data('modal-open')
      },
      init: function () {
          var s = Snap('#svg');
          svgModal.pathElement = s.select('path');
          this.events();
      },
      events: function () {
          svgModal.showOverlay.on('mouseenter', this.btnHover);
          svgModal.showOverlay.on('mouseleave', this.btnHover);
          svgModal.showOverlay.on('click', this.toggleModal);
          svgModal.closeOverlay.on('click', this.toggleModal);
      },
      btnHover: function (e) {
          e.preventDefault();
          var $this = $(this);
          if (!svgModal.modalOpen) {
              svgModal.pathElement.stop().animate({ 'path': svgModal.btnHovered ? svgModal.paths.default : svgModal.paths.active }, 250, mina.easeout);
              svgModal.btnHovered = !svgModal.btnHovered;
          }
      },
      toggleModal: function (e) {
          e.preventDefault();
          var $this = $(this);
          setTimeout(function () {
              $('body').toggleClass('modal-active');
          }, 100);
          svgModal.pathElement.stop().animate({ 'path': svgModal.paths.modalOpen }, 300, mina.easeout, function () {
              svgModal.pathElement.stop().animate({ 'path': svgModal.modalOpen ? svgModal.paths.active : svgModal.paths.default }, svgModal.modalOpen ? 800 : 300, svgModal.modalOpen ? mina.elastic : mina.easeout);
          });
          svgModal.btnHovered = false;
          svgModal.modalOpen = !svgModal.modalOpen;
      }
  };
  svgModal.init();
}());
