Achieving Active Navigation with Bootstrap CSS
Creating customized navigation menus in Bootstrap while maintaining the active class functionality can be a challenge. This article addresses the issue of why the active class does not switch when scrolling or clicking on menu items.
HTML Structure
The provided HTML essentially comprises a list of items with corresponding anchors:
<code class="html"><ul class="menu">
<li><a href="#" aria-current="page">Home</a></li>
<li><a href="#about">About Us</a></li>
<li><a href="#contact">Contact</a></li>
</ul></code>
Custom CSS
The CSS styles for the menu define basic properties such as list styling, float, and padding. Additionally, hover states and active states are specified:
<code class="css">.menu {
list-style: none;
}
.menu > li {
float: left;
}
.menu > li > a {
color: #555;
float: none;
padding: 10px 16px 11px;
display: block;
}
.menu > li > a:hover {
color: #F95700;
}
.menu a[aria-current="page"],
.menu a[aria-current="page"]:hover {
color: #F95700;
}</code>
JavaScript for Active State
To correctly switch the active class, JavaScript is required. The following snippet handles clicks on menu items and ensures that only one item is active at a time:
<code class="javascript">$('.navbar li').click(function(e) {
$('.navbar li.active').removeClass('active');
var $this = $(this);
if (!$this.hasClass('active')) {
$this.addClass('active');
}
e.preventDefault();
});</code>
Additional Considerations
In this specific case, the Bootstrap navigation, represented by .navbar in the JavaScript, is being targeted. However, it is always important to consider the specifics of your implementation when adapting this solution.
By utilizing the provided HTML, CSS, and JavaScript, you can achieve a customized navigation menu with the desired active class functionality.

How can I include CSS only on some pages?
Jun 11, 2025 am 12:01 AM
There are three ways to selectively include CSS on a specific page: 1. Inline CSS, suitable for pages that are not frequently accessed or require unique styles; 2. Load external CSS files using JavaScript conditions, suitable for situations where flexibility is required; 3. Containment on the server side, suitable for scenarios using server-side languages. This approach can optimize website performance and maintainability, but requires balance of modularity and performance.

What is 'render-blocking CSS'?
Jun 24, 2025 am 12:42 AM
CSS blocks page rendering because browsers view inline and external CSS as key resources by default, especially with imported stylesheets, header large amounts of inline CSS, and unoptimized media query styles. 1. Extract critical CSS and embed it into HTML; 2. Delay loading non-critical CSS through JavaScript; 3. Use media attributes to optimize loading such as print styles; 4. Compress and merge CSS to reduce requests. It is recommended to use tools to extract key CSS, combine rel="preload" asynchronous loading, and use media delayed loading reasonably to avoid excessive splitting and complex script control.
