连字符 | hyphens
该hyphens
CSS属性指定当文字跨越多行时如何自动换行断字。您可以完全禁止连字符,在文本中手动指定点来使用连字符,或者让浏览器在适当的地方自动插入连字符。
/* Keyword values */
hyphens: none;
hyphens: manual;
hyphens: auto;
/* Global values */
hyphens: inherit;
hyphens: initial;
hyphens: unset;
连字规则是依语言而定的。在HTML中,语言是由lang
属性决定的,只有当这个属性存在时且有合适的连字符字典可用时,浏览器才会使用连字符。在XML中,要求必须使用xml:lang
属性。
注意:定义如何执行连字符的规则没有被规范明确定义,所以确切的连字符规则可能因浏览器而异。

语法
该hyphens
属性被指定为从下面的列表中选择出的单个关键字。
可能值
none
——即使文字中的字符表示换行符,文字也不会在换行符处断开。行将只包含在空白处。
manual
——只有在单词内部的字符表示换行的情况下,单词才会被断开。有关详细信息,请参阅下面的建建议的换行时机。
auto
——只要遵循它所选择使用的任何规则,浏览器就可以自由地在合适的连字点处自动分词。但是,建议的换行时机(请参阅下面的建议换行时机)将覆盖自动断点选择。
注:该auto
设置的行为取决于语言被正确标记,以便可以选择相应的断字规则。您必须使用lang
这个HTML属性指定一种语言,以确保自动连字符应用于您所选择的语言。
建议换行时机
有两个Unicode字符可用于在文本中手动指定潜在的换行点:
U + 2010(HYPHEN):该“硬”连字符表示可见的换行时机。即使该行实际上没有被断开,连字符仍然呈现。
U + 00AD(SHY):一个不可见的“软”连字符。这个字符不是可见的,它只是标志着浏览器应该断行的位置。在HTML中,您可以使用­
插入一个软连字符。
形式语法
none | manual | auto
实例
这个例子使用三个类,其中一个用于hyphens
属性的每个可能的配置。
HTML
<ul>
<li><code>none</code>: no hyphen; overflow if needed
<p lang="en" class="none">An extreme­ly long English word</p>
</li>
<li><code>manual</code>: hyphen only at &hyphen; or &shy; (if needed)
<p lang="en" class="manual">An extreme­ly long English word</p>
</li>
<li><code>auto</code>: hyphen where the algorithm is deciding (if needed)
<p lang="en" class="auto">An extreme­ly long English word</p>
</li>
</ul>
CSS
p {
width: 55px;
border: 1px solid black;
}
p.none {
-webkit-hyphens: none;
-ms-hyphens: none;
hyphens: none;
}
p.manual {
-webkit-hyphens: manual;
-ms-hyphens: manual;
hyphens: manual;
}
p.auto {
-webkit-hyphens: auto;
-ms-hyphens: auto;
hyphens: auto;
}

层叠样式表( Cascading Style Sheets )是一种用来表现 HTML 或 XML 等文件样式的计算机语言。CSS 不仅可以静态地修饰网页,还可以配合各种脚本语言动态地对网页各元素进行格式化。
