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>; }
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>; }
//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>; }
2.font-variant
<span style="color: #800000;">p </span>{<span style="color: #ff0000;"> font-variant</span>:<span style="color: #0000ff;"> small-caps</span>; }
解释:设置字体是否以小型大写字母显示。
值 |
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>; }
//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>; }
3.font-style
<span style="color: #800000;">p </span>{<span style="color: #ff0000;"> font-style</span>:<span style="color: #0000ff;"> italic</span>; }
解释:设置字体是否倾斜。
值 |
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>; }
解释:设置字体是否加粗。
值 |
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>; }
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>; }
6.font
<span style="color: #800000;">p </span>{<span style="color: #ff0000;"> font</span>:<span style="color: #0000ff;"> 50px 楷体</span>; }
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>
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。
