Blinking Text Test, 2
Suppressing Blinking Controlled by CSS

What Is Being Tested?

This document is part of a suite of pages designed to test the implementation of the W3C's User Agent Accessibility Guidelines (UAAG). In particular, this page is designed to test implementation of UAAG checkpoint 3.3:

3.3 Allow configuration to render animated or blinking text as motionless, unblinking text. [Priority 1] Content only.

Content type labels: VisualText.

Note: A "stock quote ticker" is an example of animated text. This checkpoint does not apply for blinking and animation effects that are caused by mechanisms that the user agent cannot recognize. This checkpoint requires configuration because blinking effects may be disorienting to some users but useful to others, for example users who are deaf or hard of hearing.

Techniques for checkpoint 3.3

Note that user agents do not need to support the blink effect in order to conform to either CSS1 or CSS2.

What Should Happen?

This page is a test of your user agent's ability to control or supress blinking text achieved using the value blink for the CSS2 text-decoration property. Note that user agents are not required to support the blink value in order to claim conformance to the CSS2 specification. Blinking text alternates between a visible and invisible state.

This is some text which should appear and disappear.

How to Provide Feedback

Please send comments and observations about this test page to <w3c-wai-ua@w3.org>. Your comments will be archived in the User Agent mailing list's public hypertext archive. Please make your observations as specific and detailed as possible. Be sure to include the following information when you report your observations to the User Agent Accessibility Guidelines Working Group:

1. operating system (including version/revision number)
2. assistive technology, if any (please include version number)
3. user agent name and version (e.g. MSIE, version 5.00.2920.0000 update versions ;q254902)
4. any special settings (i.e. any changes you or your adaptive equipment made to your user agent's default configuration)
5. whether your user agent supports the blink value for the text-decoration property--that is, did the text appear to blink?
6. whether you were able to stop the blinking text from blinking. Please provide the following specific information:
   1. how did you suppress the blinking text? Please list all the keystrokes, mouse click(s), etc. you used to stop the text from blinking, in the order they were executed
   2. did the text remain visible after you suppressed blinking?
   3. does your user agent provide an option for slowing the blinking rate? did it provide you with the option to slow or suppress blinking?
   4. if you are using assistive technology, what effect did the blinking text have on your ability to review this page's content?
