height

Defines the height of an element’s content area. The content area is the space inside the padding, border, and margin of the element.

Syntax

height: <value>;

where <value> can be one of the following:

  • Length values: 100px
  • Percentage values: 20%
  • Keyword values: auto, max-content, min-content, fit-content

Note: In the case that box-sizing is set to border-box, the height of the element includes the content, padding and border. The height property will be overwritten by the min-height, and max-height properties.

Example 1

Set the height of the .box element to be 100px:

.box {
height: 100px;
}

Example 2

Set the height of the .box element to be 100px including the padding and the border:

.box {
box-sizing: border-box;
padding: 20px;
border: 2px solid black;
height: 100px;
}

Example 3

Set the height of the .child-box element to be half the height of the .parent-box element:

<div class="parent-box">
<div class="child-box">I am 50% as tall as my parent.</div>
</div>
.parent-box {
border: 2px solid blue;
width: 200px;
height: 200px;
}
.child-box {
border: 2px solid red;
height: 50%;
}
