* Value: auto || start || end || center || justify ||

* Inherited:yes
* Percentages:no
* Media::visual
*
* This property describes how the last line of the inline content of a block
* is aligned. This also applies to the only line of a block if it contains a
* single line, the line preceding a BR element and to last lines of
* anonymous blocks. Typically the last line is aligned like the other lines
* of the block element, this is set by the 'text-align' property. However,
* in some situations like when the 'text-align' property is set to
* 'justify', the last line may be aligned differently.
