CSS 2.1 Reference: height Property

The height property is used to specify the height of the content area of an element's box. (See CSS Box Model for information concerning the boxes that are generated for elements.) The height property does NOT include the height of the padding, border, or margin areas.

This property is specified by using a length, percentage, or keyword, according to the syntax shown above. Negative values are not permitted. If a percentage value is used, the value will be a percentage of the containing block.

CSS Example: The height properties are set using length values.

  #tst1 {height: 100px;}
  #tst2 {height: 200px;}

• auto - The height is set automatically by the browser.
• inherit - The inherit keyword is used to specify that the value for this property should be taken from the parent element. If inherit is used with the root element, then the initial value for this property will be used.
