Guideline 3 : Allow configuration not to render some content that may reduce accessibility
Checkpoint 3.3 : Toggle animated or blinking text
Allow configuration to render animated or blinking text content as motionless, unblinking text. Blinking text is text whose visual rendering alternates between visible and invisible, at any rate of change.
Sufficient techniques
In this configuration, the user must still have access to the same text content, but the user agent may render it in a separate viewport (e.g., for large amounts of streaming text).
The user agent may satisfy this checkpoint by always rendering animated or blinking text as motionless, unblinking text.
Normative inclusions and exclusions
This checkpoint must be satisfied for all implemented specifications that support blinking; see the section on conformance profiles.
This checkpoint does not apply for blinking and animation effects caused by mechanisms that the user agent cannot recognize.
Checkpoint 4.3 addresses user control of blinking effects caused by rapid color changes.
