Subject: Solution for the Editor's Note on Adapting Text SC?

Hello Everyone,

The editor's note on the adapting Text SC currently states [1]:

"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."

Gregg V has suggested adding 2 bullet points and a note [2] to solve this:


5. text color to any color that the user agent allows background color to any color that the user agent allows 6. font-family to any font family that the user agent allows and has immediately available

NOTE: If the user is changes the text and background colors - then the author is not responsible for meeting any contrast SC other than for the colors specified as default by the author.


In addition Scott Hollier seems to be in support of the color bullet and has commented [3], "The Adapting Text SC would be a fantastic addition. As a high contrast color user its often the case that websites don't account for user-defined colors and you end up in situations where text gets garbled or you can end up with for example, black text on a black background. The specifics of this need some work but I'm a big fan of the principle."

Should we add Gregg's bullets?

Previous discussion and related info:

The LVTF previously discuss dropping the font bullet from the SC. With the exception of Icon Fonts, which we hope to address via Issue 297 [4] the LVTF hasn't found a page yet where the font family cannot be overridden via bookmarklet or user stylesheet or VIP-PDF Reader. The TF resolved to remove the font bullet last April. [5]

The "Adapting Text user to content requirements table" [6] tries to sort out what actually breaks for users and how to address it.



Kindest Regards,






Laura L. Carlson
