We all know that we should use modal windows when there are steps the user needs to do before the task can be completed. Using a modal window instead of a full page allows users to maintain the context of their task.
On small screens (mobile) a modal windows should covers the entire screen. Presenting a potentially complex task that people can complete within the context of the modal view.
But on desktop, the width/height will fit the content. But should it be vertically align in the center of the screen or from the top of the screen (with a big margin)?
or the question could be:
Are we aligning modal windows in the middle because there's a reason or just because it feels right?
