3. Add the following CSS code to create the flip effect:

/* Flip effect for before and after images */
.twentytwenty-container {
    position: relative;
    perspective: 1000px; /* Perspective for the flip effect */
}

.twentytwenty-before, .twentytwenty-after {
    position: absolute;
    width: 100%;
    height: 100%;
    backface-visibility: hidden;
    transition: transform 0.6s; /* Smooth transition */
}

.twentytwenty-before {
    transform: rotateY(0deg); /* Initial state */
}

.twentytwenty-after {
    transform: rotateY(180deg); /* Flipped state */
}

.twentytwenty-container:hover .twentytwenty-before {
    transform: rotateY(-180deg); /* Flip effect on hover */
}

.twentytwenty-container:hover .twentytwenty-after {

        var halfWidth = $(this).width() / 2;
        var offsetX = e.offsetX - halfWidth;
        var flip = (offsetX / halfWidth) * 180; // Adjust flip based on mouse position

        $(this).find('.twentytwenty-before').css('transform', 'rotateY(' + flip + 'deg)');
        $(this).find('.twentytwenty-after').css('transform', 'rotateY(' + (flip - 180) + 'deg)');
    });

    $('.twentytwenty-container').on('mouseleave', function() {
        $(this).find('.twentytwenty-before').css('transform', 'rotateY(0deg)');
        $(this).find('.twentytwenty-after').css('transform', 'rotateY(180deg)');
    });
})(jQuery);

Step 4: Save and Publish

FAQs

1. Can I apply the flip effect to only one image in the slider?
Yes, you can customize the flip effect to apply to only one image (either before or after) by adjusting the CSS and JavaScript. For instance, remove the CSS and JavaScript for the after image if you only want the effect on the before image.

2. Will the flip effect impact my website’s performance?
The flip effect uses CSS and JavaScript, which are generally lightweight and should not significantly impact your site’s performance. However, it’s a good practice to monitor your site’s speed after adding new features.

3. Can I adjust the flip angle or speed?
Yes, you can modify the flip angle and speed by adjusting the values in the CSS and JavaScript. In the CSS, change the rotateY values. In the JavaScript, adjust the calculation for the flip effect.

4. Is it possible to add a flip effect without coding?
While some advanced effects like the flip require custom CSS and JavaScript, premium slider plugins may offer built-in flip effects that can be enabled through the plugin’s settings without needing to code.

5. Will the flip effect work on mobile devices?
The flip effect should work on mobile devices, but touch interactions may differ from mouse interactions. It’s advisable to test the effect on various devices to ensure a consistent experience.
