HTML<wbr> 元素  — 一个文本中的位置,其中浏览器可以选择来换行,虽然它的换行规则可能不会在这里换行。

内容类别

Flow content, phrasing content.

HTML元素

属性

这个元素只包含全局属性。

说明

在 UTF-8 编码的页面中, <wbr> 表现为 U+200B ZERO-WIDTH SPACE (零宽空格)代码点。特别是,它表现为 Unicode bidi BN 代码点,也就是说,它对 bidi-ordering 没有影响:<div dir=rtl>123,<wbr>456</div>当不拆成的两行时候, 展示123,456 而不是 456,123


同理, <wbr>元素不会在换行的地方引入连字符。为了使连字符仅仅在行尾出现,使用连字符软实体 (&shy;) 来代替。


这个元素首先在Internet Explorer 5.5中实现,并在HTML5中正式定义。

例子

The Yahoo Style Guide recommends breaking a URL before punctuation, to avoid leaving a punctuation mark at the end of the line, which the reader might mistake for the end of the URL.

<p>http://this<wbr>.is<wbr>.a<wbr>.really<wbr>.long<wbr>.example<wbr>.com/With<wbr>/deeper<wbr>/level<wbr>/pages<wbr>/deeper<wbr>/level<wbr>/pages<wbr>/deeper<wbr>/level<wbr>/pages<wbr>/deeper<wbr>/level<wbr>/pages<wbr>/deeper<wbr>/level<wbr>/pages</p>
