What is an overlay popup?

What is a Popup Overlay? Popup overlays, also known as lightbox popups and modal popups, are website popups that are designed to cover the screen by darkening or blurring out the background. The problem is that popup overlays are often a huge hit—or a huge miss.

What is the difference between popup and overlay?

An overlay is what we now commonly call a pop-up. These are not new windows or tabs but rather displays or lightboxes that appear overtop of the main content on the page.

What is the difference between overlay and modal?

A modal is something where you are doing work inside that new box rather than in the content that's underneath it. So a sign-in form that overlays, that pops up over the rest of the content, but that doesn't allow you to engage with this content underneath it, that would be considered a modal.
