Bootstrap 4传送带定位和控件

Question

我正在努力对齐轮播导航控件和文本。尝试了很多事情，但仍然无法弄清楚。 正如您在图像上看到的，控件太靠近内部文本。

1. 如何将左右控件移至边缘？
2. 如何更改文本div的宽度？ （我尝试使用w-75，但随后所有文本均未向左对齐）

谢谢！

 <div id="myCarousel" class="carousel slide text-center" data-ride="carousel">
            <!-- Indicators -->
            <ol class="carousel-indicators">

              <li data-target="#myCarousel" data-slide-to="1"></li>
