Definition and Usage
The height property sets the height of an element.
The height of an element does not include padding, borders, or margins!
If height: auto; the element will automatically adjust its height to allow
its content to be displayed correctly.
If height is set to a numeric value (like pixels, (r)em, percentages) then if
the content does not fit within the specified height, it will overflow. How the
container will handle the overflowing content is defined by the
overflow property.
Note: The min-height and
max-height properties override the
height property.
