font-feature-settings
版本：CSS3
font-feature-settings 属性用于控制OpenType字体中的高级印刷功能。
示例
/* 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;

语法
font-feature-settings :normal| <string>[ <integer>| on| off]
取值
- normal：文本使用默认设置进行布局。
- <string>：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。
- <integer>：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。
| 默认值 | normal |
| 适用于 | 所有元素，也适用于::first-letter、::first-line |
| 继承性 | 有 |
| 动画性 | discrete |
| 计算值 | 指定值 |
