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.
