Re: Re[2]: Colour Luminosity/Contrast for form inputs/controls/components

Let's capture that. The double focus could be a sufficient technique to
meet the requirement of sufficient contrast of focus indicator when there
are many colours of intereactive elements.

Seems a bit of a hack to require both border, and Outline ... but maybe ok
while we lobby CSS WG to provide two colour borders for accessibility.

Cheers,
David MacDonald
