title: css infinite animation with linear characteristics
body: <p>does some one have an idea of how the upper menu that is moving is done in the following page
  <a href="http://www.tis.tv/" rel="nofollow noreferrer">http://www.tis.tv/</a></p>
  
  <p>I have tried animation-transform but it once the animation is over the div comes back, and its nothing similar to the one on the page.</p>
  
  <pre><code>.footer div{
      -webkit-animation-name: prop-600;
      -webkit-animation-duration: 20s;
      -webkit-animation-iteration-count: infinite;
  } 
  </code></pre>
  
  <p>I have being searching for hours and i have no clue thank you,</p>
