引导活动选项卡通过覆盖背景可见

Bootstrap active tab is seen through overlay background

本文关键字：覆盖 背景 活动 选项      更新时间：2023-09-26

我正在使用Bootstrap和Bootstrap选项卡。我在自定义叠加背景中淡出，由于某种原因，活动选项卡在过渡期间会穿过背景。我想不通这个。

.HTML

<div id="container" style="display:none;">
  <div id="bg">
  </div>
</div>
<div>
  <!-- Nav tabs -->
  <ul class="nav nav-tabs" role="tablist">
    <li role="presentation" class="active"><a href="#home" aria-controls="home" role="tab" data-toggle="tab">Home</a></li>
    <li role="presentation"><a href="#profile" aria-controls="profile" role="tab" data-toggle="tab">Profile</a></li>

    <li role="presentation"><a href="#settings" aria-controls="settings" role="tab" data-toggle="tab">Settings</a></li>
  </ul>
  <!-- Tab panes -->
  <div class="tab-content">
    <div role="tabpanel" class="tab-pane active" id="home">...</div>
    <div role="tabpanel" class="tab-pane" id="profile">...</div>
    <div role="tabpanel" class="tab-pane" id="messages">...</div>
    <div role="tabpanel" class="tab-pane" id="settings">...</div>

.CSS

#bg {
  background: rgba(0, 0, 0, 0.50);
  bottom: 0;
  left: 0;
  right: 0;
  top: 0;
  position: fixed;
  z-index: 2000;
}
* {
  transition: all 250ms;
}

.JS

$('#container').fadeIn();

更改 

#bg {z-index: 2000;}

自

#bg {z-index: 0;}

或

.nav-tabs>li {
z-index: 2001;
}
