Question

我选择了this free bootstrap theme，我的问题是我想创建透明面板，但是当我设置opacity: 0.8;面板中的文本时，当然会变得透明，这不是我的事情想要发生。我尝试使用这个CSS代码，但看起来标题和正文后面还有一些东西，面板不透明。

.panel-transparent .panel-heading{
    background: rgba(122, 130, 136, 0.2)!important;
}

.panel-transparent .panel-body{
    background: rgba(46, 51, 56, 0.2)!important;
}

编辑 - 示例HTML：

<div class="panel panel-primary">
  <div class="panel-heading">
    <h3 class="panel-title">Panel primary</h3>
  </div>
  <div class="panel-body">
    Panel content
  </div>
</div>

Answer 3

只需使用上面链接中提到的“ bg透明”即可； https://getbootstrap.com/docs/4.1/utilities/colors/

这样；

<div class="panel panel-primary">
  <div class="panel-heading">
    <h3 class="panel-title bg-transparent text-dark">Panel primary</h3>
  </div>
  <div class="panel-body bg-transparent text-white">
    Panel content
  </div>
</div>

并且绝对确保不要忘记添加引导程序。
