Flashing and Blinking and Animation
To reduce the risk of optically-induced seizures, elements on the page should not flicker at a rate between 2 and 55 times per second. To identify possible sources of screen flickering, look at this list of possible causes:
Animated .gifs: Are they essential to the design or can they be replaced with non-animated .gifs? If the animation is necessary, consider that the speed of the animation can be different than intended, because different computers of different processor speeds and different connection speeds can render the animations differently.
Applets: Is the applet necessary?
Any third-party plug-ins: Are they necessary?
Blinking or Scrolling text: These are almost never necessary and should be removed or replaced with static text.
