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
