I recently asked a question regarding what I consider "modal dialogs".
Is there any definitive research on modal/overlay forms? Specifically, dismissing behaviors
I didn't get a good answer because it seems people have different notions of what a modal dialog box is.
You can see from my language, I labored on what to call it.
When I think of modal dialog box, I think of the classic Action/Cancel popups from the application era. However I don't know what the agreed upon name is for all the modern web and mobile iterations we see today.
However, I DO believe I meant modal-window or window-overlay[-box].
To me, a modal-window is the combination of an overlay covering the entire window with a new smaller interface window embedded in it demanding user action. I am not sure if a modal-dialog implies all the same features.
When I search wikipedia for modal dialog, modal window returns as the result
They also mention lightbox. But that has distinct implementations and is an additional tag in my opinion.
If I had a vote, I would say it's good to change modal-dialog to modal-window
