|OTHER TEXT TRICKS
by Florence W Deems
Justify means that the text left margin is straight vertically, the second row lined up vertically below the first line, and so on - plus the right margins also appear to be equal in length with each other. If we do not put in the CSS style tag for "justify," then all the right margins will look ragged and some lines will end with more white space than other lines.
To accomplish this, all the spaces between all the words are made the same width. This is called justifying the inter-word spaces, too.
As you can see, the two paragraphs above are justified.
