Align the last line of a paragraph
This is something you might rarely need. But nice to know. You can align the last line of text separately to the rest.
This comes handy for designs that need justified text alignment, but you want the last line to be aligned to the right. (Which is, to be honest, the only useful case I can imagine.)
Text-Align Justify: Purring snowflakes whispered through tinsel whiskers, while gingerbread paws kneaded festive beneath twinkling mittens.
Text-align-last Right: Candlelit paws tiptoed through christmas cookie shadows, while winter cats caroled marshmallow dreams into spiced catnip.
