Help finding the right term

I am trying to look up how to get the effect where the whole page is either darkened or blurred and a pop up opens over the page to display information - I thought it was called windowshade but I get all sorts of other stuff when I look that up. Does anyone know what the correct name for this effect is?

I think it's lightbox your looking for.
