word-spacing

value: normal | <length> | inherit
initial value: normal
inherited: yes
percentages: N/A
applicable to: all elements with text

 The word-spacing property allows you to add or reduce space between each word in a line of text. The value can be entered as px or em. This may be something that you use for dramatic effect, for headings, or to make a font more readable.

Example:

p.quote {word-spacing: 10px;}
