For more information about the supported length units, see CSS Length Units Reference. percentage Integer, followed by a percent sign (%). The value is a percentage of the height of the parent object.

The property is read/write for all objects except the following, for which it is read-only: currentStyle. The property has a default value of normal. The Cascading Style Sheets (CSS) attribute is not inherited.

Remarks

Line height is the distance between the descender of the font and the top of the internal leading of the font.

If a formatted line contains more than one object, the maximum line height applies. In this case, negative values are not allowed.

Microsoft Internet Explorer 3.0 supports the line-height attribute through the font attribute.
