Problem Description
When creating web pages using Twitter Bootstrap 3, sometimes the tab view gradient effect does not work properly. Specifically, when switching tabs, the page content does not fade, but appears or disappears directly, lacking a smooth transition.
Problem Analysis
There are several reasons why the tab view transition effect may not work properly. Common causes include missing necessary CSS classes, conflicting JavaScript scripts, or incorrect usage. The key to resolving this issue is to correctly set the CSS classes and JavaScript scripts.
Solution
Below are some common solutions to fix the CSS Twitter Bootstrap 3 tab view transition effect not working properly.
Checking CSS Classes
When creating tabs using CSS Twitter Bootstrap 3, ensure that each tab includes the correct CSS classes. Common tab CSS classes include nav-tabs (for creating the tab navigation bar) and tab-content (for containing tab content). Ensure these CSS classes are correctly applied to the corresponding HTML elements.
The following is the HTML structure of a sample tab page:
<ul class="nav nav-tabs">
<li class="active">Tab 1</li>
<li>Tab 2</li>
<li>Tab 3</li>
</ul>
<div class="tab-content">
<div id="tab1" class="tab-pane fade in active">
<p>Content of Tab 1</p>
</div>
<div id="tab2" class="tab-pane fade">
<p>Content of Tab 2</p>
</div>
<div id="tab3" class="tab-pane fade">
<p>Content of Tab 3</p>
</div>
</div>
Note that the tab content requires an additional CSS class, tab-pane, and uses the fade and in classes to achieve the fade effect. Ensure each tab has a unique ID for reference in links in the navigation bar.
Importing Necessary JavaScript Files
To enable the fade effect for the tab view, ensure that the necessary JavaScript files are correctly imported in the page. CSS Twitter Bootstrap 3 uses jQuery and Bootstrap’s JavaScript plugins to achieve the fade effect for the tab view.
Please ensure the following JavaScript files are correctly imported in your HTML file:
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
These files can be included via a CDN (Content Delivery Network) or downloaded to a local server and referenced from there. Make sure to use the latest versions of jQuery and Bootstrap.
Check for JavaScript Conflicts
If you’re using other JavaScript libraries or plugins on your page, they might conflict with the CSS Twitter Bootstrap 3 JavaScript scripts, affecting the tab view’s gradient effects. In this case, check all JavaScript scripts and resolve any conflicts.
Example
Here is an example page demonstrating the CSS Twitter Bootstrap 3 tab view gradient working properly:

<li>Tab 2</li>
<li>Tab 3</li>
</ul>
<div class="tab-content">
<div id="tab1" class="tab-pane fade in active">
<p>This is the content for tab 1. </p>
</div>
<div id="tab2" class="tab-pane fade">
<p>This is the content for tab 2. </p>
</div>
<div id="tab3" class="tab-pane fade">
<p>This is the content for tab 3. </p>
</div>
</div>
<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/js/bootstrap.min.js"></script>
