Lightbox
Definition
A lightbox is a modal window that opens over the page to display content in full size (image, video, form) while dimming the background. It is the classic behavior when you click a product photo and it expands to full screen. Used well, it focuses user attention on specific content without leaving the page.
Why it matters for your business
Lightboxes increase interaction rates on product visuals and galleries because users can zoom in without losing their navigation context. For an e-commerce SMB or portfolio site, it is an essential component for turning browsing into conversion. They also work well for displaying contact forms without redirecting to another page.
