Changing Color in JS Option Panel

2 min read 09-11-2024

In modern web development, creating a dynamic and interactive user interface is essential. One way to enhance user experience is by allowing users to change colors in a JavaScript-based option panel. This article will guide you through the process of creating a simple option panel where users can change the background color of a webpage using JavaScript.

Setting Up the HTML Structure

First, we need to set up a basic HTML structure for our option panel. The HTML will consist of a selection of color options and a button to apply the selected color.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Color Change Option Panel</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div id="option-panel">
        <h1>Change Background Color</h1>
        <select id="color-picker">
            <option value="white">White</option>
            <option value="lightblue">Light Blue</option>
            <option value="lightgreen">Light Green</option>
            <option value="lightcoral">Light Coral</option>
            <option value="yellow">Yellow</option>
        </select>
        <button id="apply-color">Apply Color</button>
    </div>
    <script src="script.js"></script>
</body>
</html>

Adding CSS for Styling

Next, we will add some basic styles to make our option panel look more appealing. You can customize the CSS as needed.

/* styles.css */
body {
    font-family: Arial, sans-serif;
}

#option-panel {
    text-align: center;
    margin: 50px;
}

button {
    padding: 10px 15px;
    background-color: #007BFF;
    color: white;
    border: none;
    border-radius: 5px;
    cursor: pointer;
}

button:hover {
    background-color: #0056b3;
}

Implementing JavaScript Functionality

Finally, we will add the JavaScript that will handle the color change when the button is clicked. This code will listen for a click event on the button, retrieve the selected color from the dropdown menu, and change the background color of the webpage accordingly.

// script.js
document.getElementById('apply-color').addEventListener('click', function() {
    const selectedColor = document.getElementById('color-picker').value;
    document.body.style.backgroundColor = selectedColor;
});

Conclusion

By following these simple steps, you have created a functional option panel that allows users to change the background color of a webpage. This example demonstrates the basics of manipulating the DOM using JavaScript, and it can be expanded further with more features, such as saving the selected color in local storage or applying transitions for smoother color changes.

Feel free to enhance this project with more colors, additional options, or even themes. Happy coding!
