<sod>*The [[World Wide Web Consortium]] - [[Web Content Accessibility Guidelines]] (WCAG) Version 2.0, produced in 2008, specifies that content should not flash more than 3 times in any 1 second period.

(Basically, it is OK to flash more than 3 times in a 1-second period if the flashing is small enough or low contrast enough.)  <ref>{{cite web|url=http://www.w3.org/TR/WCAG20/#seizure|title=Web Content Accessibility Guidelines (WCAG) 2.0|publisher=[[W3C]]|accessdate=2010-11-03|date=8 Dec 2008}}</ref>{{not in citation given}}{{dubious}}<eod>
