Thedetermines how a line of text with text-align set to "justify" is padded to fill the line. A value of zero causes all the spacing to be added evenly between letters, whereas a value of one causes all the spacing to be added around the breaks between words. The default value is 0.5, which is half and half and gives generally good results.
