ToggleClass to link to individual divs off-canvas?

I have multiple images on a page, and I'd like each image on click to link to a separate page off-canvas. Currently, each image links to the same page, and I'd like to figure out how to hit each one separately. I've simplified the code below, but here's a link to the full Pen: http://ift.tt/1Ei81CX

<div class="container">

  <section id="slider">
    <div id="section-1" class="fullpage">
      <a href="#slider">
      <h1>Header</h1>
      <a href="#" class="menu-close">⇉</a>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quo aliquid iste consectetur incidunt dolorem inventore rerum, tempore quis nulla iure eveniet nostrum, saepe itaque mollitia modi ex. Cum, nam odio.</p>
    </div>

    <div id="section-2" class="fullpage">
      <a href="#slider">
      <h1>Header</h1>
      <a href="#" class="menu-close">⇉</a>
      <p>porem ipsum dolor sit amet, consectetur adipisicing elit. Quo aliquid iste consectetur incidunt dolorem inventore rerum, tempore quis nulla iure eveniet nostrum, saepe itaque mollitia modi ex. Cum, nam odio.</p>
    </div>
 </section>

 <ul id="images">
   <li><a href="#section-1" class="menu-link"><img src="http://ift.tt/1GtSxvC" alt="" /></a></li>
   <li><a href="#section-2" class="menu-link"><img src="http://ift.tt/1GtSxvC" alt="" /></a></li>
 </ul>

</div><!--container-->

The CSS:

.container {
    background: gray;
    -webkit-transition: 1.15s ease;
    -moz-transition: 1.15s ease;
    -o-transition: 1.15s ease;
    transition: 1.15s ease;
}

#slider {
    position: absolute;
    top: 0;
    bottom: 0;
    left: -100%;
    width: 100%;
    height: 100%;

    -webkit-transform: translate(0px, 0px);
    -moz-transform: translate(0px, 0px);
    -o-transform: translate(0px, 0px);
    -ms-transform: translate(0px, 0px);
    transform: translate(0px, 0px);
    -webkit-transition: 1.15s ease;
    -moz-transition: 1.15s ease;
    -o-transition: 1.15s ease;
    transition: 1.15s ease;
}

#slider > div {
    position: absolute;
}

.container.active {
    -webkit-transform: translate(100%, 0);
    -moz-transform: translate(100%, 0);
    -o-transform: translate(100%, 0);
    -ms-transform: translate(100%, 0);
    transform: translate(100%, 0);
}

.fullpage {
    height: 100vh;
}

And the JS:

$('.menu-link').click(function() {
  $('#slider').toggleClass('active');
  $('.container').toggleClass('active');
});

$('.menu-close').click(function() {
  $('#slider').toggleClass('active');
  $('.container').toggleClass('active');
});
