title: Using jquery to make image bounce up and down in a looping animation
body: <p>I am new to jquery and want to create an effect of kids bouncing on a jumping castle (up and down motion) for a website I'm developing.</p>
  
  <p>Below is a very cut down structure of the site. How do I make her move up and down as though she's on a jumping castle?</p>
  
  <p>The id for the image is <strong>ballerina</strong>.</p>
