The text-autospace CSS property allows you to specify the space applied between Chinese/Japanese/Korean (CJK) and non-CJK characters.

Syntax

text-autospace: normal;
text-autospace: no-autospace;
text-autospace: ideograph-alpha;
text-autospace: ideograph-numeric;
text-autospace: punctuation;
text-autospace: insert;
text-autospace: replace;
text-autospace: ideograph-alpha insert;
text-autospace: ideograph-alpha replace;
text-autospace: ideograph-numeric insert;
text-autospace: ideograph-numeric replace;
text-autospace: punctuation insert;
text-autospace: punctuation replace;
text-autospace: auto;

/* Global values */
text-autospace: inherit;
text-autospace: initial;
text-autospace: revert;
text-autospace: revert-layer;
text-autospace: unset;

Values

• normal
  • : Creates the default behavior to automatically apply spacing between CJK and non-CJK characters and around punctuation. This value has the same effect as applying both ideograph-alpha and ideograph-numeric.
• <autospace>
  • : Provides more control over spacing behaviors. It accepts:
    • the keyword no-autospace, or
    • a combination of one or more of ideograph-alpha, ideograph-numeric, and punctuation, optionally followed by insert or replace.
  • no-autospace
    • : Disables automatic spacing between CJK and non-CJK characters.
  • ideograph-alpha
    • : Adds spacing only between ideographic characters (such as Katakana and Han) and non-ideographic letters (such as Latin). It does not add spacing between ideographic characters and non-ideographic numbers.
  • ideograph-numeric
    • : Adds spacing only between ideographic characters (such as Katakana and Han) and non-ideographic numbers (such as Latin). It does not add spacing between ideographic characters and non-ideographic letters.
  • punctuation
  • : Adds non-breaking spacing around punctuation as required by language-specific typographic conventions.
  • insert
    • : If there are no spaces between the ideograph and non-ideographic scripts the user agent automatically inserts the correct spacing.
  • replace
    • : If there are spaces between the ideograph and non-ideographic scripts, such as U+0020, the user agent automatically replaces it with the correct spacing.
• auto
  • : Lets the browser choose typographically appropriate spacing. The spacing may vary across browsers and platforms.

Note

If neither insert nor replace are specified, the behavior is the same as insert.

Note

This property is additive with the {{CSSXRef("word-spacing")}} and {{CSSXRef("letter-spacing")}} properties. The amount of spacing contributed by the letter-spacing setting is added to the spacing created by text-autospace. The same applies to word-spacing.
