Adapting Text



Discussion of the issue is available in Issue 74, Issue 78, and Issue 79. To file comments on this proposal, please raise new issues for each discrete comment in GitHub.

If the technologies being used allow the user agent to adapt style properties of text, then no loss of essential content or functionality occurs by adapting all of the following:

  1. line height (line spacing) to at least 1.5 times the font size
  2. spacing underneath paragraphs to at least 2 times the font size
  3. letter spacing (tracking) to at least 0.12 times the font size
  4. word spacing to at least 0.16 times the font size

Examples of text that are typically not affected by style properties are open captions and images of text, which are not expected to adapt.

The Working Group seeks to include overriding text color, background color, and font-family as part of this SC, but is not yet able to identify a way to do so that is sufficiently testable.
