Here is a quick edit of Enve's answer. I do like roXor's solution, but background images are not necessary. And everbody seems to forgot a preventDefault as well.

$(document).ready(function() {
  $(".slidingDiv").hide();

  $('.show_hide').click(function(e) {
    $(".slidingDiv").slideToggle("fast");
    var val = $(this).text() == "-" ? "+" : "-";
    $(this).hide().text(val).fadeIn("fast");
    e.preventDefault();
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" class="show_hide">+</a>

<div class="slidingDiv">
