title: any generalized functions for fadeIn fadeOut?
body: <p>Jquery:</p>
  
  <pre><code>$(document).ready(function () {
      $('#myfirstDiv').click(function () {
          $('#seconDiv').fadeIn("fast");
      });
      $('#closeBtn').click(function () {
          $('#seconDiv').fadeOut("fast");
      });
  });
  </code></pre>
  
  <p>there is multiple usage of these functions in my site, with different ids for Div and Buttons.<br/>
  How could I generalize these functions for every Div and Button?</p>
