- <p>When rendered according to the
- <a href="http://www.w3.org/TR/CSS21/visudet.html#propdef-line-height">css 2.1 spec</a>,
- the 200% text in the second two div divs, those for which line-height of the parent
- are specified in em or %, will overlap, the child divs being 1/2 the height of their containing
- divs; while the first div div will be 2/3 the height of its containing div,
- and its text won't overlap. The overlapping text in the latter div divs is because the spec requires the calculated
- line-height specified in em or % be inherited by the children. In contrast, it is <number> itself that is inherited by
- the children, which allows the line-height specified to be applied in reference to the font-size of the child div instead of
- the ancestor.</p>
