title: How to set up a lightbox in Ruby on Rails?
body: <p>I am running Ruby on Rails 3 and I would like to use a <a href="http://en.wikipedia.org/wiki/Lightbox_%28JavaScript%29" rel="nofollow">lightbox</a> in my application, for example to show a login form and sign in users. I would like to use the <em>Prototype</em> framework.</p>
  
  <p><strong>How is that possible?</strong> <em>Do you have any advice or alert on this?</em></p>
  
  <p>P.S.: I would like to write as much as possible my proprietary code. Is that advisable?</p>
