title: Slick slider - Add class to 'slick-active'
body: <p>I am working with slick slider.</p>
  
  <p>Does anyone know how to add a class to the 'slick-active' slider?</p>
  
  <p>I am showing 3 slides and I would like to have a different class on each one: one class for the left slide, another for the center and another for the slide on the right.</p>
  
  <p>For example, for the active left slide: 'slick-active-left'.</p>
