添加箭头到bootstrap轮播

Question

我在互联网上找到了这个代码，我想从中学习。我想要做的是添加两个箭头（没有阴影，只有箭头）。向左移动一个箭头，向右移动一个箭头左右移动它们。

我尝试了很多东西，但到目前为止还没有任何工作。你能帮助我吗？

代码

HTML：

   <div class="carousel slide text-center" id="zalen-carousel">
                                     <ol class="carousel-indicators">
                                        <li data-target="#zalen-carousel" data-slide-to="0" class="active"></li>
                                        <li data-target="#zalen-carousel" data-slide-to="1"></li>
                                        <!-- <li data-target="#testimonial-carousel" data-slide-to="2"></li> -->
                                      </ol>





                                    <div class="carousel-inner">
                                        <div class="item active">

Answer 1

首先，添加Bootstrap的导航箭头 - 它们应该放在.carousel-inner div下面的HTML中：

<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
        <span class="glyphicon glyphicon-chevron-left" aria-hidden="true"></span>
        <span class="sr-only">Previous</span>
      </a>
  <a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
        <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
        <span class="sr-only">Next</span>
      </a>

然后，修改CSS：

.carousel-control {
  background-image: none !important;
}

.carousel-control .glyphicon-chevron-left, .carousel-control .glyphicon-chevron-right {
  color: red;
}

Answer 2

添加此CSS

.carousel-control.left , .carousel-control.right
{
  background-image: none !important;
}
