Jamous,
For number 3, if you are using NVDA, use SHIFT+NVDA+O. If it says off screen, it's invisible to the sighted user. If it really is invisible or hidden through CSS, you won't see it. You need to be very careful, though, because as you read with NVDA, you have to keep spot checking to see if text is off screen. Sometimes, you get a clue that text is off screen if you tab to a control and only hear part of what you read with arrow keys, or if a sighted person says that a link is shorter than you think it is. With colors, there is no easy way to do minimum contrast checking because no screen reader color values are reliable. The only thing you may be able to do is inspect elements in your browser, get it to show you the CSS for the elements, and do the math.

NVDA is coming out with a revised color scheme, but that doesn't guarantee how it renders in the document object model, so it's unreliable to count on.

If I come up with something better, I will definitely talk about it.

Thanks.

Jim
