如何重新设计引导滑块

Question

我正在尝试更改“轮播”上一个和下一个的设计，我尝试使用此代码

.carousel-control-prev {
  content: 'prev';
  font-size: 55px;
  color: red;
}

<a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">
  <span class="carousel-control-next-icon" aria-hidden="true"></span>
  <span class="sr-only">Next</span>
</a>

我尝试做的是：

<a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">
  <span class="swiper-button-prev swiper-button-white" aria-hidden="true">
      <div class="swiper-button-prev swiper-button-white">prev</div>
  </span>
  <!--
  <span class="sr-only">Previous</span>
  -->
</a>

Answer 1

改变了轮播prev和next的设计...有什么问题？

编辑 2：为箭头插入 HTML 实体。删除文本装饰

.carousel-control {
  font-size: 55px;
  color: red;
  text-decoration: none;
}

<a class="carousel-control-prev carousel-control" href="#carouselExampleControls" role="button" data-slide="prev">
  <span class="swiper-button-prev swiper-button-white" aria-hidden="true">
    <div class="swiper-button-prev swiper-button-white">&rsaquo;</div>
  </span>
</a>

 <a class="carousel-control-next carousel-control" href="#carouselExampleControls" role="button" data-slide="next">
  <span class="carousel-control-next-icon" aria-hidden="true"></span>
  <span class="sr-only">&lsaquo;</span>
</a>
