二.字体设置

我们可以通过 CSS 文本样式来修改字体的大小、样式以及形态。

1.font-size

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-size</span>:<span style="color: #0000ff;"> 50px</span>;
}
Copy after login

解释:设置文本的大小。属性值如下表:

 

//先设置父元素字体大小

<span style="color: #800000;">body </span>{<span style="color: #ff0000;">
    font-size</span>:<span style="color: #0000ff;"> 50px</span>;
}
Copy after login

 

//再设置相对小一些

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-size</span>:<span style="color: #0000ff;"> smaller</span>;
}
Copy after login

 

 2.font-variant

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-variant</span>:<span style="color: #0000ff;"> small-caps</span>;
}
Copy after login

解释:设置字体是否以小型大写字母显示。

 

说明

normal

表示如果以小型大写状态,让它恢复小写状态。

small-caps

让小写字母以小型大写字母显示。

 //先让父元素设置小型大写

<span style="color: #800000;">body </span>{<span style="color: #ff0000;">
    font-variant</span>:<span style="color: #0000ff;"> small-caps</span>;
}
Copy after login

 

//让子元素设置恢复小写 

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-size</span>:<span style="color: #0000ff;"> 50px</span>;<span style="color: #ff0000;">
    font-variant</span>:<span style="color: #0000ff;"> normal</span>;
}
Copy after login

 

3.font-style

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-style</span>:<span style="color: #0000ff;"> italic</span>;
}
Copy after login

解释:设置字体是否倾斜。

说明

normal

表示让倾斜状态恢复到正常状态。

italic

表示使用斜体。

oblique

表示让文字倾斜。区别在没有斜体时使用。

 

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-weight</span>:<span style="color: #0000ff;"> bold</span>;
}
Copy after login

解释:设置字体是否加粗。

说明

normal

表示让加粗的字体恢复正常。

bold

粗体

bolder

更粗的字体

lighter

轻细的字体

100 ~ 900 之间的数字

600 及之后是加粗,之前不加粗

 

在目前计算机和浏览器显示中,只有 bold 加粗,其他更粗更细,目前体现不出来。

 

5.font-family

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-family</span>:<span style="color: #0000ff;"> 微软雅黑</span>;
}
Copy after login

解释:使用指定字体名称。这里使用的字体是浏览者系统的字体。有时为了兼容很多浏览者系统的字体,可以做几个后备字体。

 

//备用字体

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font-family</span>:<span style="color: #0000ff;"> 楷体,微软雅黑,宋体</span>;
}
Copy after login

 

6.font

<span style="color: #800000;">p </span>{<span style="color: #ff0000;">
    font</span>:<span style="color: #0000ff;"> 50px 楷体</span>;
}
Copy after login

解释:字体设置简写组合方式。格式如下:[是否倾斜|是否加粗|是否转小型大写] 字体大小 字体名称;

 

三.Web 字体

虽说可以通过备用字体来解决用户端字体缺失问题,但终究用户体验不好,且不一定备用字体所有用户都安装了。所以,现在 CSS 提供了 Web 字体,也就是服务器端字体。

 

//服务器提供字体

<span style="color: #800000;">@font-face </span>{<span style="color: #ff0000;">
    font-family</span>:<span style="color: #0000ff;"> abc</span>;<span style="color: #ff0000;">
    src</span>:<span style="color: #0000ff;"> url('BrushScriptStd.otf')</span>;
}<span style="color: #800000;">

p </span>{<span style="color: #ff0000;">
    font-size</span>:<span style="color: #0000ff;"> 50px</span>;<span style="color: #ff0000;">
    font-family</span>:<span style="color: #0000ff;"> abc</span>;
}<span style="color: #800000;"><br></span>
Copy after login

英文字体文件比较小,而中文则很大。所以,中文如果想用特殊字体可以使用图片。大面积使用特殊中文字体,就不太建议了。

The new version is online,
