| 值 | 描述 |
|---|---|
| number | 定义字体的 aspect 值比率。 可使用的公式： 首选字体的字体尺寸 * （font-size-adjust 值 / 可用字体的 aspect 值）=可应用到可用字体的字体尺寸 举例： 如果 14px 的 Verdana（aspect 值是 0.58）不可用，但是某个可用的字体的 aspect 值是 0.46，那么替代字体的尺寸将是 14 * (0.58/0.46) = 17.65px。 |
| none | 默认。如果此字体不可用，则不保持此字体的 x-height。 |
| inherit | 继承父元素的字体大小调整属性 |
