在 Bootstraps 轮播中更改箭头颜色

Question

我显然在这里错过了一些愚蠢简单的东西。我有白色背景的图像，所以我希望能够编辑 Bootstraps Carousel 上的箭头，以便它们可见。这么多改变箭头的颜色（不是我所做的背景）。

CSS

 .carousel-control-prev-icon, .carousel-control-next-icon {
    height: 100px;
    width: 100px;
    outline: black;
    background-color: rgba(0, 0, 0, 0.3);
    background-size: 100%, 100%;
    border-radius: 50%;
    border: 1px solid black;
}

轮播 HTML

 <div class = 'col-md-9'>

    <div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">

        <ol class="carousel-indicators">
            <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
            <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
        </ol>

        <div class="carousel-inner" role="listbox">
            <div class="carousel-item active">
                <img class="d-block img-fluid" src="carousel/Bars%20and%20Dots.jpg" alt="First slide" class = 'img-responsive'>
            </div>

            <div class="carousel-item">
                <img class="d-block img-fluid" src="carousel/murial.jpg" alt="Second slide" class = 'img-responsive'>
            </div>

            <div class="carousel-item">
                <img class="d-block img-fluid" src="carousel/Upper%20Partialism%20album%20covers004white.jpg" alt="Third slide" class = 'img-responsive'>
            </div>
        </div>

        <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
            <span class="carousel-control-prev-icon" aria-hidden="true"></span>
            <span class="sr-only">Previous</span>
        </a>

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

    </div>

</div>

我希望这有效，干杯。

 .carousel-control-prev-icon,
.carousel-control-next-icon {
  height: 100px;
  width: 100px;
  outline: black;
  background-size: 100%, 100%;
  border-radius: 50%;
  border: 1px solid black;
  background-image: none;
}

.carousel-control-next-icon:after
{
  content: '>';
  font-size: 55px;
  color: red;
}

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

Answer 2

用纯 CSS 将它们换成很棒的字体：

 .carousel-control-prev-icon, .carousel-control-next-icon {
  background-image: none;
}

.carousel-control-prev-icon:after, .carousel-control-next-icon:after {
  content: "\f053";
  font-family: 'Font Awesome 5 Free', sans-serif;
}

.carousel-control-next-icon:after {
  content: "\f054";
}
