如何使swiper.js滑块(拇指图库)显示为块而不是内联

<div class="swiper-container">
  <div class="swiper-wrapper">
    <!-- 滑块内容 -->
    <div class="swiper-slide">Slide 1</div>
    <div class="swiper-slide">Slide 2</div>
    <div class="swiper-slide">Slide 3</div>
  </div>
</div>

.swiper-container {
  display: block;
}

.swiper-slide {
  display: block;
}

var swiper = new Swiper('.swiper-container', {
  // 配置参数
});
