RE: Visual Indicators

Hello David, hello all,

in fact we do not agree to widen the scope of the upcoming “Visual Indicators” Success Criterion to inline links in a block of text,
as inline links are handled in SC 1.4.1, and the Success Criteria should be free of overlaps.
For easier reference, I linked some documents which are relevant in this context.
Some are from WCAG 2.0, some are from WCAG 2.1.
Use of Color:

Hi all

On the call John Avila, John Kirkwood and Brooks said they would like to see the scope of the Visual Indicators SC widened. Here is my attempt to do that while not impacting current design conventions.

      Visual Indicators: For controls needed to progress or complete a process, and inline links in a block of text, differences in spacing between elements, typeface, font size, or font style are not used as the only visual means of conveying interaction.

             Exception: An underline is a sufficient indicator that a control is actionable.
