The WP Before After Image Slider is a versatile tool for showcasing visual changes and comparisons between images. A standout feature that can add a unique touch to your sliders is the image overlay invert effect. This effect inverts the colors of the overlay image, creating a striking visual contrast and enhancing the impact of your comparisons. In this article, we’ll guide you through applying the image overlay invert effect to your WP Before After Image Slider, ensuring a comprehensive and user-friendly approach.

What is Image Overlay Invert?

Image overlay invert refers to the process of inverting the colors of the overlay image in a before-after slider. When you apply this effect, colors in the overlay image are reversed, turning light colors to dark and vice versa. This technique can dramatically alter the appearance of the overlay, making it stand out or providing a distinct contrast to the underlying image.

Why Use Image Overlay Invert in Before-After Sliders?

1. Visual Impact: Inverting colors can make the overlay image more visually striking, drawing attention to specific details or differences.
2. Enhanced Contrast: Provides a clear contrast between the before and after images, making comparisons more noticeable.
3. Artistic Flair: Adds a creative and unique touch to your sliders, enhancing their aesthetic appeal.
4. User Engagement: Encourages users to interact with your slider and explore the differences between images in a new way.

How to Add Image Overlay Invert to WP Before After Image Slider?

Step 1: Install and Activate a Before-After Slider Plugin

1. Log in to your WordPress dashboard.
2. Navigate to Plugins > Add New.
3. Search for “WP Before After Image Slider”.

Step 3: Apply the Invert Effect with Custom CSS

To add the invert effect, you’ll need to use custom CSS. Follow these steps:

1. Go to Appearance > Customize in your WordPress dashboard.

/* Invert effect for before and after images */
.twentytwenty-container {
    position: relative;
}

}
