【问题描述】：
我正在使用 html、css 和 bootstrap 来设计一些选项卡。 这是我现在得到的结果：
点击屏幕上的任何地方，我都会得到我有代码的原始结果。
The result after clicking on the screen anywhere
如何解决这两个问题：
在选择/单击任何选项卡时，选项卡文本颜色必须变为红色。正如您在我的代码中看到的那样，我已经尝试过 active 关键字。
无需点击屏幕即可立即显示实际结果。
我的代码：
<div class="container">
<div class="row">
<div class="col-md-12">
<div class="tab" role="tabpanel">
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active"><a href="#medicalNotes" aria-controls="home" role="tab" data-toggle="tab">Medical Notes</a></li>
<li role="presentation" ><a href="#medication" aria-controls="profile" role="tab" data-toggle="tab">Medications</a></li>
<li role="presentation"><a href="#allergies" aria-controls="messages" role="tab" data-toggle="tab">Allergies</a></li>
<li role="presentation"><a href="#vitalsh" aria-controls="messages" role="tab" data-toggle="tab">Vital Social history</a></li>
<li role="presentation"><a href="#familyhh" aria-controls="messages" role="tab" data-toggle="tab">Family Health history</a></li>
</ul>
<div class="tab-content tabs">
