Bootstrap轮播。如何减少手机上的 header 和指标 phone

Question

当我将 chrome 的 window 拧紧时，字幕和旋转木马的圆形指示器的大小在移动设备和全屏中是相同的。有没有可能在手机上变小？

感谢关注，抱歉英语不好！

您可以使用媒体查询为 CSS 属性指定其他值：

例如：

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');

@media (max-width: 767px) {
  .carousel-caption h1 {  /* Header */
    font-size: 20px;
  }
  .carousel-caption p {  /* Paragraph */
    font-size: 12px;
  }
  .carousel-indicators li {  /* Indicators */
    width: 8px;
    height: 8px;
  }  
  .carousel-indicators .active {  /* Active indicator */
    width: 10px;
    height: 10px;
  }  
}

@media (max-width: 480px) {
  .carousel-caption h1 { /* Header */
    font-size: 16px;
  }
  .carousel-caption p { /* Paragraph */
    font-size: 10px;
  }
  .carousel-indicators li {  /* Indicators */
    width: 6px;
    height: 6px;
  }  
  .carousel-indicators .active {  /* Active indicator */
    width: 8px;
    height: 8px;
  }  
}

.carousel img {
  width: 100%;
}

<div id="carousel-example-generic" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
    <li data-target="#carousel-example-generic" data-slide-to="1"></li>
    <li data-target="#carousel-example-generic" data-slide-to="2"></li>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner" role="listbox">
    <div class="item active">
      <img src="//placehold.it/900x300/c69/f9c/?text=First" alt="">
      <div class="carousel-caption">
        <h1>Header</h1>
        <p>Paragraph.</p>
      </div>
    </div>
    <div class="item">
      <img src="//placehold.it/900x300/9c6/cf9/?text=Second" alt="">
      <div class="carousel-caption">
        <h1>Header</h1>
        <p>Paragraph.</p>
      </div>
    </div>
    <div class="item">
      <img src="//placehold.it/900x300/69c/9cf/?text=Third" alt="">
      <div class="carousel-caption">
        <h1>Header</h1>
        <p>Paragraph.</p>
      </div>
    </div>
  </div>

  <!-- Controls -->
  <a class="left carousel-control" href="#carousel-example-generic" 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="#carousel-example-generic" role="button" data-slide="next">
    <span class="glyphicon glyphicon-chevron-right" aria-hidden="true"></span>
    <span class="sr-only">Next</span>
  </a>
</div>
