Description
Prefer the
top
+right
+bottom
+left
trick to make the fullscreen modal taking the whole window height and width, instead of an height based on the viewportvh
as in mobile browser this CSS unit may not represent correctly the visible area.Motivation and Context
The CSS viewport
vh
is the larger possible view height and does not change with the visible area height (this is an intended behavior for optimization reason).Because of that, the modal may be taller than the visible area and the window, and is then incorrectly positioned.
