Text style adjustable

foundational

Normative Text

The presentation of each of the following text style properties can be adjusted, without loss of content or functionality, to meet the corresponding values for the content’s language, or, if the language is not listed in the table, of the language listed with the most similar orthography.

The requirement is that the text is manipulable and the style attributes can be overridden.

Except when

the text style property is hard-coded, such as raw text that is capitalized or hyphenated.

The metrics in the following table are still to be determined; the current content is an example.

Characteristic	Arabic	Chinese	English	Hindi	Russian
Font face
Font width
Text decoration			Most text is not bold, italicized, and/or underlined Text is not bold and italicized at the same time Underlines are only used for links
Letter spacing
Capitalization
Automatic end-of-line hyphenation			Disabled

Blocks of text readable (minimum) and Text style readable (minimum) are based on common usage, and their adjustable and enhanced counterparts are based on readability research. We need more readability research in these languages.

#2 is true.
