在容器的左边和右边，你可以使用::after和::before伪选择器添加不透明度、模糊或渐变。

此效果与Swiper API无关（是.swiper的某个transparent edges）。
最简单的方法是添加css mask。

.swiper {
  /* MASK */
  -webkit-mask-image: linear-gradient(90deg, transparent 0%, rgba(0, 0, 0, 1) 20%, rgba(0, 0, 0, 1) 80%, transparent 100%)
}

**最好通过媒体查询在移动的上禁用。

Demo：

var swiper = new Swiper(".mySwiper", {
  slidesPerView: 4,
  spaceBetween: 30,
  mousewheel: true,
  centeredSlides: true,
  loop: true,
  pagination: {
    el: ".swiper-pagination",
    clickable: true,
  },
});
