Learn how to create a barcode generator using HTML, CSS, and JavaScript with this comprehensive guide.
Follow step-by-step instructions, complete with code examples, to build a functional barcode generator from scratch.
This project is perfect for enhancing your web development skills and understanding the integration of these technologies.
By the end of this tutorial, you'll have a working barcode generator that you can customize and expand upon to suit your needs.
Introduction
Barcodes are essential tools for modern inventory management and product identification. Creating a barcode generator using HTML, CSS, and JavaScript is a practical way to understand web development and enhance your skill set.
This guide will walk you through the steps to build a barcode generator from scratch, providing code examples and explanations along the way.
Setting Up the HTML Structure
First, we need to create a basic HTML structure for our barcode generator.
This structure will include an input field for the text to be converted into a barcode and a button to generate the barcode. Here is the HTML code:
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Barcode Generator</title> <link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<h1>Barcode Generator</h1>
<input type="text" id="barcodeInput" placeholder="Enter text">
<button onclick="generateBarcode()">Generate Barcode</button>
<div id="barcodeOutput"></div>
</div> <script src="script.js">
</script>
</body>
</html>
Adding Styles with CSS
Next, let's add some CSS to style our barcode generator.

We will create a simple and clean design to make the generator user-friendly. Here's the CSS code:
body { font-family: Arial, sans-serif; background-color: #f4f4f4;
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
margin: 0;
}.container
{ background-color: #fff;
padding: 20px;
border-radius: 8px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1);
text-align: center;}input, button
{ padding: 10px;
margin: 10px 0;
width: 80%;
border: 1px solid #ccc;
border-radius: 4px;}button
{ background-color: #007bff;
color: #fff;
border: none;
cursor: pointer;}button:hover
{
background-color: #0056b3;
}
Implementing JavaScript Functionality
Finally, we need to write the JavaScript code to generate the barcode.
We will use the JsBarcode library, which simplifies barcode generation. Here is the JavaScript code:
function generateBarcode()
{
var input = document.getElementById("barcodeInput").value;
var output = document.getElementById("barcodeOutput");
JsBarcode(output, input,
{ format: "CODE128", lineColor: "#000", width: 2, height: 100, displayValue: true });
}
document.addEventListener("DOMContentLoaded",
function()
{ var script = document.createElement("script");
script.src = "https://cdn.jsdelivr.net/npm/[email protected]/dist/JsBarcode.all.min.js"; script.onload = function()
{ console.log("JsBarcode library loaded.");
};
document.body.appendChild(script);
});
Conclusion
By following these steps, you have created a functional barcode generator using HTML, CSS, and JavaScript.
This project not only demonstrates how to use these technologies together but also provides a useful tool for generating barcodes.
Feel free to expand on this project by adding more features or customizing the design to fit your needs.
