  <p>And i am using this javascript for responsiveness.</p>
  
  <pre><code>jQuery(document).ready(function(){
      jQuery(".home_carousel").slick({
          dots: false,
          autoplay: true,
          infinite: true,
          slidesToShow: 3,
          slidesToScroll: 1,
           responsive: [
              {
                breakpoint: 990,
                settings: {
                slidesToShow: 2
                }
              },
              {
                breakpoint: 668,
                settings: {
               arrows: false,
               centerMode: false,
               slidesToShow: 1
                }
              }
          ]
      });         
  });
  </code></pre>
