where <value> can be one of the following:

• Length values: 300px
• Percentage values: 33%
• Keyword values: max-content, min-content, fit-content

Note: In the case that box-sizing is set to border-box, the min-height of the element includes the content, padding and border. min-height overrides the height and max-height properties.

Example 1

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

.box {
  border: 2px solid black;
  min-height: 100px;
}
