* This property selects the type of justify alignment. It affects the text
* layout only if 'text-align' is set to 'justify'. That way, UA's that do
* not support this property will still render the text as fully
* justified, which most of the time is at least partially correct. Typically
* the text-justify property does not affect the last line, unless the last
* line itself is justified. Most of the text-justify values affects
* writing systems in very specific ways.
