3. Flashing

Identify Content

Visually identify any content that flashes. Flashing is content that rapidly alternates between two or more states that vary significantly in contrast.

When flashing content IS found, the result for Test ID 3.A, 2.1.3-flashing is NOT TESTED.

Test Name Test ID Test Condition
2.3.1-flashing 3.A If NO flashing content is found, then this Test Condition DOES NOT APPLY (DNA) If flashing content IS found, then this test should be recorded as NOT TESTED.

Note:

Multiple requirements are specified for conforming flashing content. To determine if requirements are met, a testing tool would be very helpful but is not available at this time. The test process will be updated when a testing tool is identified. Until then, the result “Not Tested” will indicate that flashing content was found.

If there is no such content, the result for the following test ID(s) is OES NOT APPLY: 3.A.

Section 508/WCAG Success Criteria Baseline Requirements

WCAG SC 2.3.1 Three Flashes or Below Threshold: Web pages do not contain anything that flashes more than three times in any one second period, or the flash is below the general flash and red flash thresholds.

  • Note: Since any content that does not meet this success criterion can interfere with a user's ability to use the whole page, all content on the Web page (whether it is used to meet other success criteria or not) must meet this success criterion. See Conformance Requirement 5: Non-Interference. Until such time that this test process includes a test for flashing content, no definitive statement can be made regarding Conformance Requirement 5 if any flashing content is present.
