CSS - writing-mode
The writing-mode
property defines whether lines of text are laid out horizontally or vertically and the direction in which blocks progress.
Example
<table> <tr> <th>value</th> <th>Vertical script</th> <th>Horizontal script</th> <th>Mixed script</th> </tr> <tr> <td>horizontal-tb</td> <td class="exampleText1">我家没有电脑。</td> <td class="exampleText1">Example text</td> <td class="exampleText1">1994年に至っては</td> </tr> <tr> <td>vertical-lr</td> <td class="exampleText2">我家没有电脑。</td> <td class="exampleText2">Example text</td> <td class="exampleText2">1994年に至っては</td> </tr> <tr> <td>vertical-rl</td> <td class="exampleText3">我家没有电脑。</td> <td class="exampleText3">Example text</td> <td class="exampleText3">1994年に至っては</td> </tr> <tr> <td>sideways-lr</td> <td class="exampleText4">我家没有电脑。</td> <td class="exampleText4">Example text</td> <td class="exampleText4">1994年に至っては</td> </tr> <tr> <td>sideways-rl</td> <td class="exampleText5">我家没有电脑。</td> <td class="exampleText5">Example text</td> <td class="exampleText5">1994年に至っては</td> </tr>
table { border-collapse:collapse; } td, th {border: 1px black solid; padding: 3px; } th {background-color: lightgray; } .exampleText1 { width:75px; writing-mode: horizontal-tb; -webkit-writing-mode: horizontal-tb; -ms-writing-mode: horizontal-tb; } .exampleText2 { height:75px; writing-mode: vertical-lr; -webkit-writing-mode: vertical-lr; -ms-writing-mode: vertical-lr; } .exampleText3 { height:75px; writing-mode: vertical-rl; -webkit-writing-mode: vertical-rl; -ms-writing-mode: vertical-rl; } .exampleText4 { height:75px; writing-mode: sideways-lr; -webkit-writing-mode: sideways-lr; -ms-writing-mode: sideways-lr; } .exampleText5 { height:75px; writing-mode: sideways-rl; -webkit-writing-mode: sideways-rl; -ms-writing-mode: sideways-rl; }

Description
The writing-mode
property defines whether lines of text are laid out horizontally or vertically and the direction in which blocks progress.
The property specifies the block flow direction, which is the direction in which block-level containers are stacked, and the direction in which inline-level content flows within a block container. Thus the writing-mode
property also determines the ordering of block-level content.

[1] An experimental implementation was available since Gecko 36. It is governed by the preference layout.css.vertical-text.enabled
, defaulting to false
until Firefox 38. From Firefox 39 and Firefox 40, the preference was true
for Nightly and DevTools editions only. Note that not all CSS widgets (e.g. tables) obey to it, yet.
[2] The implementation in Internet Explorer differs from the specification. See the related article in the Internet Explorer Dev Center.
[3] Bidirectional and rtl scripts are supported in vertical modes only since Gecko 42.
