How to Create a Before and After Slider in WordPress?

Creating a before and after slider in WordPress is straightforward, especially with the help of plugins. Here’s how you can do it:

Step 1: Choose the Right Plugin

WordPress offers various plugins that allow you to create a before and after slider with ease. Some of the most popular options are:

• WP Before After Image Slider by CodeCanel
• Before After Image Slider for Elementor
• Smart Slider 3
• Envira Gallery

In this guide, we’ll use the Twenty20 Image Before-After Plugin, which is one of the most user-friendly and feature-rich plugins for creating such sliders.

Step 2: Install and Activate the Plugin

1. Log in to your WordPress dashboard.
2. Navigate to Plugins > Add New.
3. In the search bar, type “Twenty20 Image Before-After.”
4. Click Install and then Activate once the plugin is installed.

Step 3: Add a Before and After Slider to Your Page or Post

After successfully activating the plugin, follow these steps to add a before and after slider to a page or post:

1. Go to Pages (or Posts) and select the page where you want to add the slider.
2. Click on the + Block button to add a new block.
3. Search for the “Twenty20” block, which is now available in your block editor.
4. Once added, you’ll need to upload your before and after images. Ensure the images are of the same dimensions for the best user experience.
5. Customize the slider settings as per your preference, such as slider direction, overlay labels (e.g., “Before” and “After”), and visibility settings.

Step 4: Customize the Slider (Optional)

If you want to further customize the look and feel of your slider, you can:

• Adjust Label Text: You can customize the text labels (e.g., Before, After) to make the slider more context-specific.
• Change Overlay Color: Adjust the overlay color to match your brand’s theme or aesthetic.
• Modify Slider Settings: Change the orientation of the slider, either vertically or horizontally, based on your design preference.

Step 5: Preview and Publish

Once you’re satisfied with the configuration, it’s time to preview how the slider looks on your page. After confirming everything is functioning properly, hit Publish or Update to make your changes live.

Step 6: Use Shortcode (Alternative Method)

If you prefer to insert the slider using shortcode, the Twenty20 plugin also provides that option:

1. Create a new post or page.
2. Use the following shortcode where you want to place the slider:

   [twenty20 before="image1.jpg" after="image2.jpg"]

Make sure to replace image1.jpg and image2.jpg with the URLs of your actual before and after images.

Step 7: Test Responsiveness

Before finalizing, ensure that your slider works well across all devices, especially mobile. Most plugins, including Twenty20, are mobile-responsive, but it’s always good to double-check.

Tips for Optimizing Your Before and After Slider

To make the most out of your before and after slider, follow these best practices:

1. Use High-Quality Images: Ensure that your before and after images are clear and high resolution. Poor quality images can ruin the impact.
2. Maintain Consistent Image Dimensions: Both images should be of the same size to ensure a smooth transition.
3. Add Descriptive Captions: Provide context by adding captions or descriptions to the slider to explain what’s being compared.
4. Optimize for SEO: Use appropriate alt text for your images to help search engines index them, boosting your SEO.
5. Test Across Devices: Test the slider on mobile devices and different browsers to ensure a smooth experience for all users.

Conclusion

Creating a before and after slider in WordPress is a powerful way to visually demonstrate the impact of your work, whether you’re in design, health, photography, or any other field. With plugins like Twenty20, the process is straightforward, allowing even beginners to add this interactive feature to their website. By following the steps above, you can set up a visually appealing slider in no time, enhancing your content presentation and driving more engagement on your site.
