RE: LVTF question

Ø  LVTF has https://github.com/w3c/wcag21/pull/124 Adapting Text (address text color, font, and spacing)

That seems to focus on setting the background to white or black – some people may need a background with less contrast.

Creating content in a way the author does not prevent the user from adjusting the colors through the user agent seems like an item that is compatible with the LVTF needs.

Brightness is not a function of the software.  that is a function of the hardware.

If they are sensitive to any bright light — they can turn the brightness down on their phone/computer — there can be no bright light.

Otherwise we would have to have an SC that says you cannot have a white background on your web page.


As for flashing  we do have SC on both strong flashing that is very large at all — and one for blinking of any size.

If you do want to have something more about blinking content you will have to have numbers.   I don’t think a blinking period is a problem, or a very small icon.   — so “any size”  is not really viable.

Do you have any data on how many people and what size a blinking area is a real problem?

Hi Folks

I was wondering if we have a SC for severe photophobia -people who get pain from intense light (any size) and flashing (any size)

There should be a semantics to mark any section of elements with flashing moving or blinking and these of these so that they can be blocked and make sure that low contrast can not be overridden

Do we have a SC that support this



All the best
