A Lightbox is a display tool commonly used in photography and design to showcase images or content in an engaging way. It typically features a darkened background that highlights the displayed item, making it stand out. Lightboxes can be used on websites to present images, videos, or galleries without navigating away from the current page. In web design, a Lightbox often appears as a modal window that overlays the main content. When a user clicks on a thumbnail image, the larger version opens in the Lightbox, allowing for a focused view. This technique enhances user experience by providing a seamless way to view additional content, such as in portfolios or product showcases.
