One of many important components of any internet utility is the navigation bar, because it permits customers to navigate by means of completely different pages and sections of the web site.
So it’s vital that you just construct a navigation bar that has the required hyperlinks, together with the best accessibility measures to make sure that your customers are capable of finding their manner inside your utility.

Dropbox. The Dropbox navbar is straightforward but efficient, with a distinguished “Merchandise” dropdown menu that permits customers to discover completely different choices.
Constructing a Navbar in React
Now that we perceive the significance of navbars, let’s dive into the method of constructing one utilizing React.
For this instance, we’ll create a navbar for an ecommerce web site referred to as “ShopNow”.
Step 1: Designing the navbar
Earlier than we begin coding, it’s important to have a transparent design in thoughts for our navbar.
For our ShopNow web site, we’ll purpose for a easy but fashionable design with the next components:
a brand on the left facet
hyperlinks to completely different sections of the web site (akin to “Merchandise”, “About Us” and “Contact”)
a buying cart icon with a badge displaying the variety of objects within the cart
a person icon for account-related actions (akin to “Signal In” and “My Account”)
Right here’s a mockup of how our navbar would possibly look.
Step 2: Organising the React challenge
Earlier than we begin constructing our navbar, we’ll must arrange a brand new React challenge. You may create a brand new React challenge utilizing Create React App by operating the next command in your terminal:
npx create-react-app shopnow
As soon as the challenge is ready up, navigate to the challenge listing and begin the event server:
cd shopnow
npm begin
Step 3: Creating the navbar element
With SPA frameworks like React, it’s vital that you just design and suppose in reusable, unbiased parts. So it’s essential to construct parts that you would be able to reuse all through your utility.
One utility of a reusable element is a navigation bar. You may create a reusable navbar element that you would be able to reuse inside your utility.
Let’s create a brand new file referred to as Navbar.js within the src listing and add the next code:
import React from ‘react’;
import ‘./Navbar.css’;
const Navbar = () => {
return (
<nav className=”navbar”>
{}
</nav>
);
};
export default Navbar;
We’ve created a purposeful element referred to as Navbar that returns a <nav> factor with a category identify of navbar. We’ll additionally create a brand new file referred to as Navbar.css in the identical listing to model our navbar.
Step 4: Including the navbar construction
Now let’s add the construction of our navbar contained in the Navbar element:
import React from ‘react’;
import ‘./Navbar.css’;
const Navbar = () => {
return (
<nav className=”navbar”>
<div className=”navbar-left”>
<a href=”/” className=”brand”>
ShopNow
</a>
</div>
<div className=”navbar-center”>
<ul className=”nav-links”>
<li>
<a href=”/merchandise”>Merchandise</a>
</li>
<li>
<a href=”/about”>About Us</a>
</li>
<li>
<a href=”/contact”>Contact</a>
</li>
</ul>
</div>
<div className=”navbar-right”>
<a href=”/cart” className=”cart-icon”>
<i className=”fas fa-shopping-cart”></i>
<span className=”cart-count”>0</span>
</a>
<a href=”/account” className=”user-icon”>
<i className=”fas fa-user”></i>
</a>
</div>
</nav>
);
};
export default Navbar;
On this code, we’ve divided the navbar into three sections:
navbar-left. This incorporates the brand, which is a hyperlink to the house web page.
navbar-center. This incorporates an unordered checklist (<ul>) of navigation hyperlinks.
navbar-right. This incorporates a buying cart icon with a badge displaying the variety of objects within the cart and a person icon for account-related actions.
We’ve additionally used Font Superior icons for the cart and person icons, which you’ll want to incorporate in your challenge by following the directions on their web site.
Step 5: Styling the navbar
Now that we have now the construction in place, let’s add some types to make our navbar look extra interesting. Open the Navbar.css file and add the next types:
.navbar {
show: flex;
justify-content: space-between;
align-items: middle;
background-color: #333;
colour: #fff;
padding: 1rem;
}
.navbar-left .brand {
font-size: 1.5rem;
font-weight: daring;
colour: #fff;
text-decoration: none;
}
.navbar-center .nav-links {
list-style-type: none;
show: flex;
margin: 0;
padding: 0;
}
.navbar-center .nav-links li {
margin-right: 1rem;
}
.navbar-center .nav-links a {
colour: #fff;
text-decoration: none;
}
.navbar-right {
show: flex;
align-items: middle;
}
.navbar-right .cart-icon,
.navbar-right .user-icon {
colour: #fff;
text-decoration: none;
margin-left: 1rem;
place: relative;
}
.navbar-right .cart-count {
background-color: #f44336;
colour: #fff;
border-radius: 50%;
padding: 0.2rem 0.5rem;
font-size: 0.8rem;
place: absolute;
prime: -0.5rem;
proper: -0.5rem;
}
Step 6: Importing and rendering the navbar
Lastly, we have to import the Navbar element and render it in our App.js file:
import React from ‘react’;
import Navbar from ‘./Navbar’;
operate App() {
return (
<div>
<Navbar /v>
{}
</div>
);
}
export default App;
Now, while you run your React app, it is best to see the navbar on the prime of the web page, as proven in this Pen.
Click on the 0.5x button within the Pen above to see the desktop format of the navbar.
Step 7: Finest Practices: Enhancing Accessibility
Constructing an accessible navbar is essential for guaranteeing that every one customers can successfully navigate your web site.
Listed below are some finest practices to comply with.
Use semantic HTML. We’ve already used semantic HTML components in our navbar code. The principle navigation part is wrapped in a <nav> factor, the checklist of hyperlinks is contained inside an unordered checklist (<ul>) with every hyperlink as an inventory merchandise (<li>), and the hyperlinks themselves are represented by <a> components.
Add ARIA roles and attributes. We are able to add the position=”navigation” attribute to the <nav> factor to point that it’s a navigation part:
<nav className=”navbar” position=”navigation”>
{}
</nav>
Guarantee keyboard accessibility. >React offers built-in help for keyboard accessibility. By default, all interactive components (akin to hyperlinks and buttons) will be centered utilizing the tab key and activated utilizing the Enter or House keys. Nevertheless, we should always check this performance to make sure it really works as anticipated in our navbar.
Present clear focus types. To offer clear focus types, we will add CSS guidelines for the :focus state of our hyperlinks and icons. Right here’s an instance of how we will model the centered hyperlinks in our navbar:
.navbar-center .nav-links a:hover {
colour: crimson;
}
You may modify the define and outline-offset properties to realize the specified focus model.
Use descriptive hyperlink textual content. In our navbar code, we’ve already used descriptive hyperlink textual content for the navigation hyperlinks (“Merchandise”, “About Us”, “Contact”). Nevertheless, we should always make sure that the hyperlink textual content for the cart and person icons can be descriptive. One technique to obtain that is by including visually hidden textual content utilizing the aria-label attribute:
<a href=”/cart” className=”cart-icon” aria-label=”Buying Cart”>
<i className=”fas fa-shopping-cart”></i>
<span className=”cart-count”>0</span>
</a>
<a href=”/account” className=”user-icon” aria-label=”Person Account”>
<i className=”fas fa-user”></i>
</a>
Make the format responsive. To make our navbar responsive, we will use CSS media queries to regulate the format and types primarily based on the display measurement. For instance, we may disguise the navigation hyperlinks on smaller screens and exchange them with a hamburger menu:
@media (max-width: 768px) {
.navbar-center .nav-links {
show: none;
}
.navbar-right {
show: flex;
align-items: middle;
}
.navbar-right .hamburger-menu {
show: block;
colour: #fff;
font-size: 1.5rem;
cursor: pointer;
}
}
Within the JavaScript code, we’d must deal with the toggling of the navigation hyperlinks when the hamburger menu is clicked.
By implementing these accessibility finest practices, we will make sure that our navbar is usable and inclusive for all customers, together with these with disabilities. Keep in mind to check your utility with numerous display readers, keyboard navigation, and different assistive applied sciences to make sure it meets accessibility requirements.
Wrapping Up
And that’s it! You now have your self a navigation bar that you would be able to reuse throughout your utility that ensures your customers are capable of finding their manner inside your app.
