            <img src="after.jpg" alt="After Image" class="after-image">
            <div class="slider"></div>
        </div>
        <button class="close">Close</button>
    </div>
</div>

This code snippet sets up a lightbox that contains the comparison slider.

Step 3: Adding CSS Styles

Next, style the lightbox and image comparison slider for a polished look. Here’s a simple CSS example:

.lightbox {

    width: 100%;
    height: 100%;
    background: rgba(0, 0, 0, 0.8);
    justify-content: center;
    align-items: center;
}

.lightbox-content {
    position: relative;
    max-width: 800px;
    width: 100%;
}

.image-comparison-slider {
    position: relative;
    overflow: hidden;
}

.before-image,
