css - 负上边距+溢出:hidden on Boostrap carousel

Question

我有一个通用的 bootstrap v3.7 旋转木马，我正试图像这样将它拉到它上面的内容上

这是通过 margin-top: -50px; 在青色 div 上完成的。但是轮播的隐藏overflow属性导致顶部在div顶部上方被截断，所以我无法实现这种覆盖设计。我修改 CSS 的尝试只破坏了轮播。可以这样做吗？

Answer 1

margin-top 应该应用到包含 .carousel 的 div，也许你在调用 carousel 的 div 上使用它；

以下代码片段是您要实现的目标:

.aboveCarousel {
  height: 300px;
  background: magenta;
}

.container {
  margin-top: -50px
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.0/js/bootstrap.min.js"></script>

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

    <!-- Wrapper for slides -->
    <div class="carousel-inner">
      <div class="item active">
        <img src="https://www.w3schools.com/bootstrap/la.jpg" alt="Los Angeles" style="width:100%;">
      </div>

      <div class="item">
        <img src="https://www.w3schools.com/bootstrap/chicago.jpg" alt="Chicago" style="width:100%;">
      </div>

      <div class="item">
        <img src="https://www.w3schools.com/bootstrap/ny.jpg" alt="New york" style="width:100%;">
      </div>
    </div>

    <!-- Left and right controls -->
    <a class="left carousel-control" href="#myCarousel" data-slide="prev">
      <span class="glyphicon glyphicon-chevron-left"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="right carousel-control" href="#myCarousel" data-slide="next">
      <span class="glyphicon glyphicon-chevron-right"></span>
      <span class="sr-only">Next</span>
    </a>
  </div>
