I’m currently diving into Tailwind CSS, and I’ve been trying to figure out the best way to highlight the currently active link in my navigation. You know how important it is for users to know where they are on the page, right? It really helps with navigation and usability. So, here’s the thing: I want to visually indicate which section of the page someone is currently viewing by changing the style of the corresponding navigation link.
I’ve been looking into different methods, but I feel a bit overwhelmed by all the options. I know Tailwind CSS provides a ton of utility classes, but I’m not entirely sure how to effectively apply them to achieve this “active link” effect. Should I use JavaScript to dynamically add a class based on the scroll position, or is there a better way that pairs well with Tailwind? If you’ve had any experience with this, I’d love to hear your thoughts.
For context, I’m working on a single-page application with several sections like “Home,” “About,” “Services,” and “Contact.” I want the navigation links to change in a way that makes it super clear which section is currently active as the user scrolls down the page. Like, when they’re on the “About” section, the “About” link in the nav should have a distinct style— maybe a different background color, bold text, or an underline.
I’ve seen some examples where people are using Intersection Observer API for this kind of thing, which sounds intriguing. But how do I integrate that with Tailwind? And what classes would you recommend using for the active state? I’m worried about having too many classes cluttering my HTML, but I also want it to be visually appealing.
If anyone has some practical examples or even snippets of code that work well for this, I’d be super grateful! Any help or even just pointing me in the right direction would be awesome. Thanks in advance for any tips or tricks you can share!

To highlight the currently active link in your navigation using Tailwind CSS, you can indeed leverage the Intersection Observer API for detecting the active section as the user scrolls. This method allows you to dynamically apply classes to your navigation links based on the viewport position. For example, when the “About” section comes into view, you can add an ‘active’ class to the “About” link. You might define your links in HTML like this:
“`html
“`
Integrate the Intersection Observer API by monitoring the sections in your single-page application. When a section enters the viewport, use JavaScript to dynamically add the ‘active’ class to its corresponding navigation link while removing it from others. Here’s a brief snippet to guide you:
“`javascript
const sections = document.querySelectorAll(‘section’);
const navLinks = document.querySelectorAll(‘nav a’);
const observer = new IntersectionObserver((entries) => {
entries.forEach(entry => {
if (entry.isIntersecting) {
navLinks.forEach(link => {
link.classList.remove(‘active’);
if (link.getAttribute(‘href’) === `#${entry.target.id}`) {
link.classList.add(‘active’);
}
});
}
});
});
sections.forEach(section => observer.observe(section));
“`
This code will maintain a clean and appealing navigation style while keeping your HTML clutter-free, leveraging Tailwind’s utility classes to indicate the active link effectively.
