font-synthesis: none; font-synthesis: weight; font-synthesis: style; font-synthesis: small-caps; font-synthesis: weight style small-caps;  /* Global values */ font-synthesis: inherit; font-synthesis: initial; font-synthesis: revert; font-synthesis: unset; 

font-synthesis

The font-synthesis CSS property controls which missing typefaces, bold, italic, or small-caps, may be synthesized by the browser.

Syntax

font-synthesis: none; font-synthesis: weight; font-synthesis: style; font-synthesis: small-caps; font-synthesis: weight style small-caps;  /* Global values */ font-synthesis: inherit; font-synthesis: initial; font-synthesis: revert; font-synthesis: unset; 

Values

Indicates that no bold, italic, nor small-caps typeface may be synthesized.

Indicates that a bold typeface may be synthesized if needed.

Indicates that an italic typeface may be synthesized if needed.

Indicates that a small-caps typeface may be synthesized if needed.

Description

Most standard Western fonts include italic and bold variants, and some fonts include a small-caps variant. However, many fonts do not. Fonts used for Chinese, Japanese, Korean and other logographic scripts tend not to include these variants, and synthesizing them may impede the legibility of the text. In these cases, it may be desirable to switch off the browser's default font-synthesis.

Formal definition

Formal syntax

none | [ weight || style || small-caps ]

Examples

Disabling font synthesis

<em class="syn">Synthesize me! 站直。</em> <br/> <em class="no-syn">Don't synthesize me! 站直。</em> 

em {   font-weight: bold; } .syn {   font-synthesis: style weight small-caps; } .no-syn {   font-synthesis: none; }
