Why the slick carrousel does not align in the center?

Question

I have used the slick slider code applyed to a Supreme before/after image slider, but i cant for some reason align it in the center of the page.

jQuery(document).ready(function() {
  jQuery('.divilife-3-col-feature-blurb-slider').slick({
    dots: true,
    slidesToShow: 3,
    slidesToScroll: 1,
    swipe: false,
    centerMode: true,
    centerPadding: '0px',
    responsive: \[{
        breakpoint: 980,
        settings: {
          slidesToShow: 2
        }
      },
      {
        breakpoint: 767,
        settings: {
          slidesToShow: 1
        }
      }\
    ]
  });

  function centerCarousel() {
    var carousel = jQuery('.divilife-3-col-feature-blurb-slider');
    var slideWidth = carousel.find('.slick-slide').width();
    var windowWidth = jQuery(window).width();
    var slideMargin = (windowWidth - slideWidth) / 2;
    carousel.css('margin-left', -slideMargin);
  }

});
