Technologies that support blinking content within an object, applet, or a plug-in.
This technique relates to Success Criterion 2.2.2: Pause, Stop, Hide (Failure).
When content that is rendered by a plug-in or contained in an applet blinks, there may be no way for the user agent to pause the blinking. If neither the plug-in, applet, nor the content itself provides a mechanism to pause the content, the user may not have sufficient time to read the content between blinks or it may be so distracting that the user will not be able to read other content on the page.
- An applet displays an advertisement on a news site. The applet blinks key words in the advertisement in order to call the user's attention to it. The blinking cannot be paused through any user agent settings and the applet does not provide a mechanism to stop it.
For each page that has blinking content in a plugin or applet:
- Determine if the content continues to blink for longer than 5 seconds.
- Determine if there is a means to pause the blinking content.
- If step #1 is true and step #2 is false, the content fails the success criterion.
