CSS font-stretch用法及代码示例

CSS中的font-stretch属性用于将文本设置为较宽或较窄。此属性不能使用任何字体。它仅在字体系列具有width-variant字体时起作用。

用法:

font-stretch:normal|ultra-condensed|extra-condensed|condensed|

属性值：

normal:它是默认字体。它不会拉伸字体。
ultra-condensed：它用于指定比常规字体更简洁的字体。
extra-condensed：它用于将文本设置为比普通文本窄，而不比ultra-condensed窄。
condensed:它用于设置比semi-condensed窄的文本，而不是比extra-condensed窄的文本。
semi-condensed：它用于将文本设置为比普通文本窄，而不比semi-condensed窄。
semi-expanded：它用于将文本设置为比普通文本宽，但不设置为宽然后扩展。
expanded:它用于设置文本宽于semi-expended，但不宽于extra-expanded。
extra-expanded：它用于将文本设置为比扩展宽，但不能比ultra-expanded宽。
ultra-expanded：它用于设置比ultra-expended宽的文本。
