twitter bootstrap 3选项卡视图淡入淡出无法正常工作

Question

我使用twitter bootstrap 3申请.fade显示淡入淡出的标签.这很好,除了第一个标签的内容没有首次显示:

http://jsfiddle.net/tVSv9/

<ul class="nav nav-tabs" id="myTab">
  <li class="active"><a href="#home" data-toggle="tab">Home</a></li>
  <li><a href="#profile" data-toggle="tab">Profile</a></li>
  <li><a href="#messages" data-toggle="tab">Messages</a></li>
</ul>

    <div id='content' class="tab-content">
      <div class="tab-pane fade active" id="home">
        <ul>
            <li>home</li>
            <li>home</li>
            <li>home</li>
            <li>home</li>
            <li>home</li>
            <li>home</li>
            <li>home</li>
        </ul>
      </div>
      <div class="tab-pane fade" id="profile">
        <ul>
            <li>profile</li>
            <li>profile</li>
            <li>profile</li>
            <li>profile</li>
            <li>profile</li>
            <li>profile</li>
            <li>profile</li>
        </ul>
      </div>
      <div class="tab-pane fade" id="messages">
          this is my message
      </div>
      <div class="tab-pane fade" id="settings"></div>
    </div>    

代码里面的问题在哪里？

Answer 1

You need to add in class to your active tab content

The reason behind is there is predefined style in bootstrap css .fade.in {opacity: 1;} so if you are using .fade in tab then you need to add .in too

See this demo

HTML

<div class="tab-pane fade in active" id="home">
