如何使用font weight调整文本的粗细程度

在网页设计中,文本常常不仅仅是用来传达信息的,同时也是用来美化页面的重要元素。在一些情况下,调整文本的粗细度可以使文字更具有视觉冲击力,也可以让文本更加易于阅读。对于前端工程师来说,了解如何使用CSS的font weight属性来调整文本粗细是十分重要的。

一、font weight属性的含义

font weight属性用于调整文本的粗细度,其可取值如下:

font-weight: normal; /* 正常 */
font-weight: bold; /* 加粗 */
font-weight: bolder; /* 更加粗 */
font-weight: lighter; /* 更加细 */
font-weight: 100 ~ 900; /* 数值越大,粗细度越高 */

需要注意的是,font weight属性只能用于支持加粗的字体,当字体不支持加粗时,该属性将不起作用。

二、使用font weight属性调整文本粗细的方法

下面给出了一些使用font weight属性调整文本粗细的示例:

1. 使用预定义的粗细值

在CSS中,可以直接使用预定义的粗细度值:normal和bold。下面是一个使用bold值调整文本粗细的样例:

这是使用bold值调整文本粗细的样例

2. 使用数值调整粗细程度

除了使用预定义的粗细值外,还可以使用数值来调整文本的粗细程度。数值越大,文本越粗。

这是粗细程度为400的文本
这是粗细程度为700的文本

3. 继承父元素的粗细度

当一个元素没有指定font weight属性时,它将会继承父元素的font weight属性。

这是加粗的文本

  
这是一个没有设置font weight的div,它的字体粗细度将继承父元素的样式

三、总结

在这篇文章中,我们学习了如何使用CSS的font weight属性来调整文本的粗细。我们了解了font weight属性的不同取值含义,并给出了使用预定义的粗细值、使用数值调整粗细度和继承父元素的粗细度三种调整文本粗细程度的方法。
