The height
CSS property specifies the height of an element. By default, the property defines the height of the content area. If box-sizing
is set to border-box
, however, it instead determines the height of the border area.

The min-height
and max-height
properties override height
.
/* <length> values */ height: 120px; height: 10em; height: 100vh; /* <percentage> value */ height: 75%; /* Keyword values */ height: max-content; height: min-content; height: fit-content(20em); height: auto; /* Global values */ height: inherit; height: initial; height: revert; height: revert-layer; height: unset;
<length>
Defines the height as an absolute value.
<percentage>
Defines the height as a percentage of the containing block's height.
auto
The browser will calculate and select a height for the specified element.
max-content
The intrinsic preferred height.
min-content
The intrinsic minimum height.
fit-content
Box will use the available space, but never more than max-content
fit-content(<length-percentage>
)
Uses the fit-content formula with the available space replaced by the specified argument, i.e. min(max-content, max(min-content, <length-percentage>))
clamp()
Enables selecting a middle value within a range of values between a defined minimum and maximum
Ensure that elements set with a height
aren't truncated and/or don't obscure other content when the page is zoomed to increase text size.

Percentages | The percentage is calculated with respect to the height of the generated box's containing block. If the height of the containing block is not specified explicitly (i.e., it depends on content height), and this element is not absolutely positioned, the value computes to auto . A percentage height on the root element is relative to the initial containing block. |
