There is a webdesign trend like the following:
http://progressive.nikadevs.com/?theme=progressive
I wonder if it possible at all to comply with contrast ratio at all?
The background is changing as you scroll, or background is a video.
What do you think?
What if the white letters have a black border?
Maybe you vote that this webdesing cannot be comply with WCAG 2.0 "AA"?
Regards,
Zsolt

You would need to make sure there is adequate contrast for each background/text combination, just like normally.

That's a Parallax type of site ...
Are you talking about the images that are scrolling at a different rate then the rest of the page? I would thing you would handle it as a normal page.

Thank you. How do you mean: handle it a normal page? I think it impossible
that every part of the background has enough contrast.
What do you think if this theme can be accessible with white letters on
changing background?

I think I understand what you mean ... I'd put the lettering in a container with a transparent background color, that would have the contrast needed. Another, but harder option, would be to have a script to vary the font color dynamically ... open source project anyone?

I kind of hope that the template demo is loaded up with every possibility, but in practice would be implemented with a bit more restraint. It would be a nightmare trying to avoid contrast issues on that demo. Maybe you could provide a button that will allow users to turn off the backgrounds?

I meant someone creating a project to change font color on the fly, depending on the background of the font.
A known background, like in a modal popup, would be best IMO.
