title: Optimize Transaction of high-definition images in Slider
body: <p>I did a parallax slider that works well, however the images are in high definition, I am using CSS3 "transaction" to navigate in the slides.</p>
  
  <pre><code>transaction: 2s margin-left;
  </code></pre>
  
  <p>the images to be very large, this waging transition.
  Like to leave softer.</p>
  
  <p>My doubts, I have to smush the images or change the type of transaction with some javascript plugin?</p>
