Question

我已经在互联网上搜索过，并且找不到最新版bootstrap的任何解决方案。

我想到了两件事：使用不透明度（由于Jumbotron中的其他每个元素都继承了它而没有工作），并且设置了一个背景图像，其不透明度我以为我以后可以改变（实际上只是从原来褪色到白色，仍然没有任何透明度。）

有一种简单的方法吗？

编辑：我的HTML的一部分：

<div class="jumbotron">

  <h1 class="display-3 text-right">name</h1>

  <hr class="my-4 text-right">
    <p class="lead text-right">description</p>
  <p class="lead text-right">
    <a class="btn btn-primary btn-lg" href="#" role="button">Learn more</a>
  </p>

</div>

Answer 1

您可以将Jumbotron的背景设置为none，以实现透明的Jumbotron。

.jumbotron {
    background: none
}
