文本竖排组合 | text-combine-upright

text-combine-upright

text-combine-upright CSS属性将多个字符的组合指定到单个字符的空间中。如果组合文本宽于1em,则用户代理必须调整到1em内的内容。所得到的组合物被视为用于布局和装饰的单个直立字形。此属性仅在垂直书写模式下有效。

这是用来产生一个在日语中称为“中横”(tate-chū-yoko)的效果,或者是以直书横向(Chinese)的方式产生的效果。

句法

可能值

none——没有特别的处理。

形式语法

none | all | [ digits <integer>? ]

实例(数字)

当数字被组合时,数字值(digital value)比所有值(all value)所需的标记要少,但是目前并没有得到浏览器的广泛支持。

<p lang="ja" class="exampleText">平成20年4月16日に</p>

.exampleText { writing-mode: vertical-lr; text-combine-upright: digits 2; font: 36px serif; }

实例(全部)

all value需要标记每个水平文本片段,但相较数字值, 目前它得到更多浏览器的支持。

<p lang="zh-Hant">民國<span class="num">105</span >年<span class="num">4</span >月<span class="num">29</span>日</p>

html { writing-mode: vertical-rl; font: 24px serif } .num { text-combine-upright: all }
