If, for example, the height
is set as 150px, and the min-height is set as 60px, the actual height of the element
is 150px, and the min-height declaration becomes redundant:
#example {
min-height: 60px;
height: 150px;
}
In the above example, the height of the element will be fixed at 150px. However,
it??™s acceptable to set min-height and height when the values are different units:
#example {
min-height: 3em;
height: 138px;
}
Here, the min-height declaration is based on em, which means that at some stage
(due to text resizing) the em height may be larger than the 138px height we??™ve set.
In cases such as this, the element will be allowed to expand further than the 138px
height, thus accommodating the resizing of the em-based text.
If the contents of a block require more vertical space than the limits that have been
set, that behavior is defined by the overflow (p. 280) property.
Value
The property takes a CSS length (px, pt, em, etc.) or a percentage. Negative length
values are illegal.
