Learn How to Create a Split Screen with CSS

In today’s digital age, web development is all about creating engaging and interactive user experiences. One popular design technique is the split screen layout, which divides a webpage into two or more sections, each displaying different content. This eye-catching layout is commonly used for showcasing contrasting elements or providing multiple pieces of information simultaneously. In this article, we’ll guide you through the process of creating a split screen layout using CSS, complete with detailed code snippets.

1. Introduction

Split screen layouts have become a popular choice for modern websites. They allow you to present multiple pieces of content side by side, enhancing the user experience. In this article, we will walk you through the steps to create your own split screen layout using CSS.

2. Understanding the Split Screen Concept

Before we dive into the code, let’s understand the concept of a split screen layout. It’s essentially a design technique that divides a webpage into two or more sections, each with its own content. This is often used to showcase contrasting information or provide a visual separation between elements.

3. Setting Up Your HTML Structure

To create a split screen, you’ll need to structure your HTML accordingly. Here’s a basic example:

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="styles.css">
    <title>Split Screen Example</title>
    <div class="split-container">
        <div class="left-section">
            <!-- Content for the left section -->
        <div class="right-section">
            <!-- Content for the right section -->

4. Styling the Split Screen

CSS Reset

Before styling our split screen, it’s a good practice to reset the default styles of HTML elements to ensure consistency across browsers. You can use a CSS reset library or create a simple reset yourself.

/* CSS Reset */
body, h1, h2, p, ul, li {
    margin: 0;
    padding: 0;

Container Styling

Now, let’s style the container for our split screen. We’ll set a background color, define its width, and add some padding for spacing.

/* Container Styling */
.split-container {
    display: flex; /* Or use 'display: grid;' for grid-based split screens */
    background-color: #f2f2f2;
    width: 100%;
    padding: 20px;

Left and Right Sections

Next, we’ll style the left and right sections. You can adjust the width and add your desired styles for each section.

/* Left Section Styling */
.left-section {
    flex: 1; /* This makes the section flexible to fill available space */
    background-color: #ffffff;
    padding: 20px;

/* Right Section Styling */
.right-section {
    flex: 1;
    background-color: #f9f9f9;
    padding: 20px;

5. Creating the Split Effect

Now comes the fun part—creating the split effect using CSS. You have two main options: Flexbox and CSS Grid.

Using Flexbox

To create a split screen using Flexbox, you can simply rely on the styles we’ve applied so far. The flex: 1; property for both left and right sections ensures they share the available space equally.

Using Grid

If you prefer CSS Grid, you can modify the container’s display property and define grid columns.

/* Using Grid for Split Screen */
.split-container {
    display: grid;
    grid-template-columns: 1fr 1fr; /* Two columns of equal width */

6. Responsive Design Considerations

When creating split screens, it’s crucial to consider responsive design. Ensure that your layout adapts gracefully to various screen sizes, from desktop to mobile devices.

7. Best Practices for Split Screen Layouts

Maintain Consistency

Keep the design consistent across sections to avoid confusing users. Use a cohesive color scheme and typography.

Optimize for Mobile Devices

On smaller screens, consider switching to a single-column layout or using media queries to adjust the design.

Accessibility Concerns

Ensure that your split screen is accessible to all users, including those with disabilities. Use proper semantic HTML elements and provide alternative text for images.

8. Troubleshooting Common Issues

Creating split screen layouts may come with challenges. Here are some common issues and how to troubleshoot them:

Content Overlap

If content overlaps on smaller screens, adjust the layout using media queries to stack sections vertically.

Browser Compatibility

Test your split screen layout on different browsers to ensure compatibility. Prefix CSS properties if needed.
