## 字体重量和样式
字体粗细可以写为文本值:
```
font-weight: normal;
font-weight: bold;
```
或者作为`100``900`的数值以100的倍数表示
```
font-weight: 400; /* equal to 'normal' above */
font-weight: 700; /* equal to 'bold' above */
```
数值及其共同描述
|价值|共同描述| | ----- | ---------------------------- | | 100 |薄(发际线)| | 200 |超轻(超轻)| | 300 |光| | 400 |正常| | 500 |中| | 600 |半大胆Demi Bold| | 700 |大胆| | 800 |额外大胆(超大胆)| | 900 |黑色(重)|
并非所有字体都可以使用所有权重。某些专用字体可能仅在一个重量(通常为`normal` `400` )中可用。
也可以相对于元素的父元素指定字体粗细(如果字体具有多个权重):
```
font-weight: lighter;
font-weight: bolder;
```
