Unnecessary limitation when defining blinking #2957

Open JAWS-test opened 1 year ago

JAWS-test commented 1 year ago

https://www.w3.org/TR/WCAG21/#dfn-blinking

switch back and forth between two visual states in a way that is meant to draw attention

The definition, if I understand it correctly, suggests that it is about the intention of the web developer and not about the effect of blinking.

I think better would be either

switch back and forth between two visual states

or

switch back and forth between two visual states in a way that draw attention

I also wonder if the limitation to 2 states is not misleading, because there can also be more than 2

I think that draws the author into things that might be user agent issues. Or even speed of computers.

RE more than 2 states — that is possible -but we need to keep it to the definition of blinking. If that is already covered by the SC I would not change the definition. If not - then I would.

SC should be testable. How can I test the intent of an author? In my opinion, the speed of the computer does not play a role in the definition, since no speed is defined in the SC (this is only the case for flashing, but not for blinking)

Yes, I understand that. I wonder if a color change from green to red to blue is not called blinking (3 states), but from green to red is called blinking (2 states) and if this distinction makes sense in terms of SC
