语法

/* 默认设置 */
font-feature-settings: normal;

/* 设置 OpenType 功能标签的值 */
font-feature-settings: "smcp";
font-feature-settings: "smcp" on;
font-feature-settings: "swsh" 2;
font-feature-settings: "smcp", "swsh" 2;

/* 全局值 */
font-feature-settings: inherit;
font-feature-settings: initial;
font-feature-settings: unset;

值

normal

文本使用默认设置进行布局。

<feature-tag-value>

在呈现文本时，OpenType要素标记值的列表被传递到文本布局引擎以启用或禁用字体特征。标签始终是4个ASCII字符的 <string> 。如果是U + 20 - U + 7E代码点范围以外的字符或字符个数不对，则整个属性无效。 
值是一个正整数。两个关键字on和off分别是1和0的同义词。如果未设置任何值，则默认值为1。对于非布尔型OpenType功能（例如，文体替代 stylistic alternates），该值意味着要选择特定的字形；对于布尔值，它是一个开关。

形式语法

normal | <feature-tag-value>#
where 
<feature-tag-value> = <string> [ <integer> | on | off ]?

实例

/* use small-cap alternate glyphs */
.smallcaps { font-feature-settings: "smcp" on; }

/* convert both upper and lowercase to small caps (affects punctuation also) */
.allsmallcaps { font-feature-settings: "c2sc", "smcp"; }

/* enable historical forms */
.hist { font-feature-settings: "hist"; }

/* disable common ligatures, usually on by default */
.noligs { font-feature-settings: "liga" 0; }

/* enable tabular (monospaced) figures */
td.tabular { font-feature-settings: "tnum"; }

/* enable automatic fractions */
.fractions { font-feature-settings: "frac"; }

/* use the second available swash character */
.swash { font-feature-settings: "swsh" 2; }

/* enable stylistic set 7 */
.fancystyle {
  font-family: Gabriola; /* available on Windows 7, and on Mac OS */
  font-feature-settings: "ss07";
}
