Learn How to Create a Full Screen Search Box with CSS and JavaScript

In today’s digital age, enhancing user experience on websites has become paramount. One effective way to do this is by implementing a full-screen search box using CSS and JavaScript. This interactive element not only adds a touch of modernity but also allows users to conveniently search for content without navigating away from the current page. In this article, we’ll guide you through the step-by-step process of creating a full-screen search box while explaining the underlying code snippets.

1. Introduction

A full-screen search box is an elegant and practical feature that enhances the user experience on websites. It allows visitors to quickly search for content without being redirected to a separate search page. In this tutorial, we’ll walk you through the process of creating a sleek and functional full-screen search box using the power of CSS and JavaScript.

2. The HTML Structure

To start, let’s set up the basic HTML structure. We’ll create a form element to hold the search input field and a submit button. The HTML might look something like this:

<!DOCTYPE html>
    <!-- Your meta tags and title here -->
    <div class="search-container">
        <form id="search-form">
            <input type="text" id="search-input" placeholder="Search...">
            <button type="submit">Search</button>
    <!-- Your content here -->

3. Styling the Search Box with CSS

To make the search box visually appealing, we’ll apply CSS styling. We’ll center the search box on the screen, use appropriate colors, and adjust the dimensions. Here’s an example of the CSS code:

    body {
        margin: 0;
        padding: 0;
        font-family: Arial, sans-serif;

    .search-container {
        display: flex;
        justify-content: center;
        align-items: center;
        height: 100vh;
        background-color: rgba(0, 0, 0, 0.8);

    #search-form {
        background-color: white;
        border-radius: 5px;
        padding: 20px;
        box-shadow: 0 2px 10px rgba(0, 0, 0, 0.2);

    #search-input {
        width: 100%;
        padding: 10px;
        border: none;
        border-bottom: 2px solid #333;
        font-size: 16px;

    button[type="submit"] {
        background-color: #333;
        color: white;
        border: none;
        padding: 10px 20px;
        border-radius: 3px;
        cursor: pointer;

4. Adding Animation Effects

Adding subtle animation effects can make the search box feel more interactive and engaging. Let’s use CSS transitions to achieve this:

    /* ... Previous CSS styles ... */

    #search-form {
        /* ... Previous styles ... */
        transition: transform 0.3s ease-in-out;

    #search-form.active {
        transform: scale(1.1);

5. JavaScript Functionality

Now, let’s make our search box functional with JavaScript. We’ll use JavaScript to toggle the visibility of the search box and apply animation effects.

    const searchForm = document.getElementById("search-form");

    document.getElementById("search-input").addEventListener("focus", () => {

    document.getElementById("search-input").addEventListener("blur", () => {

6. Ensuring Responsiveness

In the mobile-first era, ensuring your search box is responsive is crucial. We’ll make some adjustments to the CSS to ensure it looks great on all screen sizes.

    /* ... Previous CSS styles ... */

    @media screen and (max-width: 768px) {
        .search-container {
            padding: 20px;

        #search-form {
            width: 100%;
            max-width: 400px;

7. Customizing Search Results

Depending on your website’s design, you might want to further customize how search results are displayed. By utilizing JavaScript and backend technologies, you can fetch and display search results in real-time. Implementing filters, sorting options, and thumbnail previews are all possibilities to enhance the user experience.

8. Implementing Accessibility

Accessibility is a critical aspect of web development. Make sure to add appropriate labels and ARIA roles to your search input for screen readers. Use semantic HTML elements and ensure that the search box is operable with keyboard navigation.

9. Testing and Debugging

Before deploying the full-screen search box, it’s essential to thoroughly test it across various devices and browsers. Utilize browser developer tools to identify and address any design or functionality issues. Pay attention to how the search box behaves when accessed on different screen sizes and orientations.

10. Conclusion

Incorporating a full-screen search box using CSS and JavaScript can greatly improve user experience on your website. By following the steps outlined in this tutorial, you’ll be able to create an interactive and visually appealing search feature that enhances engagement and functionality.
