Re: jquery effects accessible?

Okay, thanks for that. I forgot that it is actually an anchor, not a div, so it is keyboard navigable. What I was really hoping for was to ask if jquery has accessibility built into it so that, if a user action triggers the pulsate effect, it would notify the user via ARIA techniques. I have heard that jquery does well with incorporating them into their widgets and the like, so I was wondering if anyone knew if they also incorporate the ARIA techniques into their effects, such as the pulsate effect.

Additionally, I do not believe that the pulsate effect is the same as using color only to convey meaning. Even if one were to turn off all color and make everything black and white, the pulsate effect would still convey meaning. Any other thoughts on this?

Hi.

Yes this has accessibility issues and 508 violations. Visual effect is equivalent to color.

508 violations:
1194.22(c) color - since you are pulsating the background, this is like using color alone to convey meaning.
1194.22(j) flicker.

You also may have some in 1194.21, and .31. On the jQuery page, the div is not keyboard navigable. To fix this, you should be able to add tabindex='-1'.
