Word Spacing
In addition to being able to adjust the space between characters, developers can adjust the amount of space between words only, using the word-spacing:  property.
  CSS
* {
  word-spacing: normal;
}
word-spacing: accepts these term values:
normal(default, 0.25em)- pixels (
px) - points (
pt) - percent (
%) - ems (
em) - …most other size terms, including negative values
 
“Why adjust word spacing?”
Like with letter-spacing: , changing the distance between words and shift the visual message of the text as part of branding or design work. Fonts are are wider can generally see a decrease in word-spacing:  without sacrificing too much legibility, although this should be a thoughtful decision.
