# G191: Providing a link, button, or other mechanism that reloads the page without any blinking content

## Applicability

This technique relates to all technologies.

This technique relates to:

- Success Criterion 2.2.2 (Pause, Stop, Hide)
  - How to Meet 2.2.2 (Pause, Stop, Hide)
  - Understanding Success Criterion 2.2.2 (Pause, Stop, Hide)

## Description

This is a general technique for allowing people who cannot use a page with blinking content to turn the blinking content off. Conformance Requirement 1 allows for conforming alternate pages to be used to meet conformance. This technique is an example of that approach applied to success criteria 2.2.2.

It is important that the page without blinking content contain all of the information that was on the page with blinking content.

Note 1: Removing the content that was blinking from the page would only be satisfactory if the blinking content was redundant with non blinking content in the original page.

Note 2: This technique can be used in combination with a style switching technique to present a page that is a conforming alternate version for non-conforming content. Refer to C29: Using a style switcher to provide a conforming alternate version (CSS) and Understanding Conforming Alternate Versions for more information.

## Examples

- A page has blinking text at the top warning users that they should not submit the page without first registering. A link at the very top of the page reloads the page with the blinking text replaced with text that is styled to be highly visible but does not blink.

## Related Techniques

- G4: Allowing the content to be paused and restarted from where it was paused
- G11: Creating content that blinks for less than 5 seconds
- G152: Setting animated gif images to stop blinking after n cycles (within 5 seconds)
- G186: Using a control in the Web page that stops moving, blinking, or auto-updating content
- G187: Using a technology to include blinking content that can be turned off via the user agent
- SCR22: Using scripts to control blinking and stop it in five seconds or less
- SCR33: Using script to scroll content, and providing a mechanism to pause it

## Tests

### Procedure

1. Check that there is a mechanism to reload page to turn off blinking.

2. Check that reloaded page has no blinking.

3. Check that the reloaded page has all the information and functionality of the original page.

### Expected Results
