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>

您可以将Jumbotron的背景设置为none
,以实现透明的Jumbotron。
.jumbotron {
background: none
}
