Examples

<meta property="schema:accessibilityFeature">
   verticalWriting
</meta>

<meta name="schema:accessibilityFeature"
      content="verticalWriting"/>

"accessibilityFeature": ["verticalWriting"]

Explanation

The verticalWriting value indicates that the writing direction is vertical (top-to-bottom).

Some readers of languages that can be written vertically or horizontally have difficulty with one or the other writing direction. Setting this value allows the reader to determine if the text will be readable for them.

Only use the verticalWriting value with languages that can be written in both horizontal and vertical directions (e.g., Japanese). Do not set this value for languages that are only written vertically.

Use the horizontalWriting value when the writing direction is horizontal.
