word-spacing
The word-spacing property specifies the spacing behavior between individual words.
It is used to increase or decrease the amount of space between individual words in a piece of text. The value specified will be added to the default space between these words.
Notes and Trivia:
The word-spacing property can be used on any kind of inline content. The term “word” refers to any inline (or inline-block) element inside an element. So the word-spacing property can be used to set or remove the spacing between elements such as a list of images inside an element.
The word-spacing property is listed as an animatable property in the CSS Transitions spec. That is, you can use CSS Transitions to change its value from one value to another.
Official Syntax
-
Syntax:
word-spacing: normal | <length> | inherit
- Initial: normal
- Applies To: all elements
- Animatable: yes
Values
- normal
- The normal inter-word space, as defined by the current font and/or the browser.
- <length>
-
This value indicates inter-word space in addition to the default space between words. Values may be negative, but there may be implementation-specific limits. See
<length>value for a list of possible values and units. - inherit
- The property takes the same specified value as the property for the element’s parent.
Notes
Word spacing algorithms may differ among browsers. Word spacing is also influenced by line justification (see text-align property). Word spacing affects the white space left between the words after the white space processing rules have been applied (see the white-space property).
It is considered best practice to use relative units to set the value of this property. If an absolute value is used, the spacing between words won’t scale as the text size scales, so you may end up with very big text with very small word spacing, or very small text with huge word spacing. em is preferred, as rem has low browser support, and because the space between words is best specified relative to the words themselves, not the root element.
Examples
The following rule increases the space between each word in the H1 element by 1em:
h1 {
word-spacing: 1em;
}
