无法在引导程序中更改轮播的长度

Question

我正在使用引导程序构建一个网站，并添加了一个轮播来显示一些图片，但我无法让它们更宽。我试图更改标签内 w- 的值，但它所做的只是以全尺寸显示图片或保持不变我希望图片宽三分之一。

<div id="myCarousel" class="carousel slide bg-inverse  w-50 ml-auto mr-auto" 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>
    <li data-target="#carouselExampleIndicators" data-slide-to="3"></li>
  </ol>
  <div class="carousel-inner" role="listbox" >
    <div class="carousel-item active" >
      <img class="d-block w-100"  src="img\core-img\cup1.jpg"  alt="First slide"  >
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="img\core-img\cup2.jpg"  alt="Second slide" >
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="img\core-img\cup3.jpg" alt="Third slide">
    </div>
    <div class="carousel-item">
      <img class="d-block w-100" src="img\core-img\cup4.jpg" alt="Fourth slide">
    </div>
  </div>
  <a class="carousel-control-prev" href="#myCarousel" 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="#myCarousel" role="button" data-slide="next">
    <span class="carousel-control-next-icon" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>

Answer 1

尝试改变你的班级：

<div id="myCarousel" class="carousel slide bg-inverse  w-50 ml-auto mr-auto" data-ride="carousel" >

到：

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