Examples

HTML

<div id="mozdiv1">Lorem ipsum dolor sit amet.</div>
<div id="mozdiv2">Lorem ipsum dolor sit amet.</div>

CSS

#mozdiv1 {
  word-spacing: 15px;
}

#mozdiv2 {
  word-spacing: 5em;
}

Accessibility concerns

A large positive or negative word-spacing value will make the sentences the styling is applied to unreadable. For text styled with a very large positive value, the words will be so far apart that it will no longer appear to be a sentence. For text styled with a large negative value, the words will overlap each other to the point where the beginning and end of each word is unrecognizable.

Legible word-spacing must be determined on a case-by-case basis, as different font families have different character widths. There is no one value that can ensure all font families automatically maintain their legibility.
