  <pre><code>var swiper = new Swiper('.s1', {
   slidesPerView: 5,
   slidesPerColumn: 2,
   spaceBetween: 30,
   nextButton: '.swiper-button-next',
   prevButton: '.swiper-button-prev',
   breakpoints: {
    1024: {
     slidesPerView: 5,
     spaceBetween: 30
    },
    768: {
     slidesPerView: 1,
     spaceBetween: 10
    },
    640: {
